Methods: We retrospectively reviewed the imaging data of the suspected patients who presented with the central nervous system (CNS) malformations and were enrolled either through the clinic or after ultrasound examinations between June 2019 and June 2023 in our institution. All imaging data were interpreted by two experienced radiologists through consensus reading.

Results: In this study, we recruited 36 patients, including two neonates, 17 infants and 17 children. Seven cases underwent an MRI examination, while the others had a CT scan. Polygyria and pachygyria malformation were the most common type of congenital neurological malformations (7 cases, 31.8%), followed by cystic changes of the cerebral parenchyma (3 cases, 13.6%). Cerebral atrophy was the most common type of secondary CNS abnormality (8 cases, 57.1%), followed by communicative hydrocephalus (3 cases, 21.4%). Five patients in the congenital group and 4 patients in the secondary group had complex malformations. In the current study group, there were 8 deaths, 12 cases with neurological sequelae, 1 case with normal development, and 15 cases lost to follow-up. There were no significant differences between the primary and secondary CNS groups in terms of the outcome for both the infants and children groups.

Conclusions: CNS malformations in the Tibetan Plateau are associated with high mortality and morbidity rates. Better utilization of imaging modalities could help design tailored treatments as early as possible.

Case Presentation A 49-year-old man presented with hemiparesis. Preoperative neuroimaging revealed a giant lesion and an AVM on the left hemisphere of the brain. Craniotomy and tumour resection were performed. The AVM was not treated and needed to be followed up. The histological diagnosis was meningioma (World Health Organization grade I). The patient was in good neurological condition postoperatively.

Conclusion This case adds to the growing literature suggesting that the association between the two lesions is complex. Besides, treatment depends on the risk of neurologic function damage and hemorrhagic stroke of meningiomas and AVMs.

Case Presentation: Hereby, we presented an 80-year-old lady with exertional dyspnea and angina. We diagnosed coronary cameral fistula from the left anterior descending artery into the left ventricle by echocardiography with “intramyocardial vascular channel and the diastolic flow”, and “multiple diastolic flow jets into heart chamber from heart wall”. We confirmed the diagnosis with coronary angiography later. In the discussion, we make a comprehensive summary to conclude all the echocardiographic findings of this disease into 3 categories.

Conclusion: We believe the identification of those findings will prompt the early diagnosis of this rare anomaly.

Case Presentation: Computer tomography angiography (CTA) revealed a left-sided 18 mm large pseudoaneurysm (PA) at the level of L5 lumbar vertebrae adjacent to the aorta. This lumbal artery originated from the false lumen of the known chronic infrarenal aortic dissection. Within a single session, the pseudoaneurysm was treated by percutaneous nonadhesive liquid embolic agent (NALEA - Onyx 34) embolization under CT-fluoroscopy guidance. Follow-up imaging showed complete occlusion of the PA.

Conclusion: This case shows the first usage of Onyx as a liquid embolic agent for this complication.

Objective: This study aimed to assess the diagnostic image quality of 3D synthetic MRI using compressed sensing (CS) in clinical practice.

Methods: We retrospectively reviewed the imaging data of 47 patients who underwent brain MRI, including 3D synthetic MRI using CS in a single session, between December 2020 and February 2021. Two neuroradiologists independently evaluated the overall image quality, anatomic demarcation, and artifacts for synthetic 3D T1-weighted, T2-weighted, fluid-attenuated inversion recovery (FLAIR), phase-sensitive inversion recovery (PSIR), and double inversion recovery images, using a 5-point Likert scale. The interobserver agreement between the two readers was assessed using percent agreement and weighted κ statistics.

Results: The overall image quality of 3D synthetic T1WI and PSIR was good to excellent, with easy or excellent anatomic demarcation and mild or no visible artifact. However, other 3D synthetic MRI-derived images showed insufficient image quality and anatomic demarcation with marked CSF pulsation artifacts. In particular, 3D synthetic FLAIR showed high-signal artifacts on the brain surface.

Conclusion: 3D synthetic MRI, at its current status, cannot completely replace conventional brain MRI in daily clinical practice. However, 3D synthetic MRI can achieve scan-time reduction using CS and parallel imaging and may be useful for motion-prone or pediatric patients requiring 3D images where time-efficiency is important.

Objective: The purpose of this study was to evaluate the clinical value of contrast-enhanced fast fluid-attenuated inversion recovery (CE FLAIR) imaging in combination with contrast-enhanced T1 weighted imaging (CE T1WI) in detecting BM of lung cancer and explore a quick and effective MRI protocol.

Material and Methods: In 201 patients with lung cancers and suspected BM, T1WI and FLAIR were performed before and after administration of gadopentetate dimeglumine. Two radiologists reviewed pre- and post-contrast images to determine the presence of abnormal contrast enhancement or signal intensity and decided whether it was metastatic or not on CE T1WI (Group 1) and CE FLAIR (Group 2). The number, locations and features of abnormal findings in two groups were recorded. Receiver Operating Characteristic (ROC) analyses were conducted in three groups: Group 1, 2 and 3(combination of CE FLAIR and CE T1WI).

Results: A total of 714 abnormal findings were revealed, of which 672 were considered as BM and 42 nonmetastatic. Superficial and small metastases(≤10mm) in parenchyma and ependyma, leptomeningeal and non-expansive skull metastases were typically better seen on CE FLAIR. The areas under ROC in the three groups were 0.720,0.887 and 0.973, respectively. Group 3 was significantly better in diagnostic efficiency of BMs than Group 1 (p<0.0001) or Group 2 (p=0.0006).

Conclusion: The combination of CE T1WI and CE FLAIR promotes diagnostic performance and results in better observation and characterization of BM in patients with lung cancers. It provides a quick and efficient way of detecting BM.

Methods: Seventy-one patients with rectal adenocarcinoma confirmed by pathology after surgical resection were collected retrospectively. According to pathology, they were divided into a poorly differentiated group (n=23) and a moderately differentiated group (n=48). The IVIM-DWI parameters and TA characteristics of the two groups were compared, and a prediction model was constructed by multivariate logistic regression analysis. ROC curves were plotted for each individual and combined parameter.

Results: There were statistically significant differences in D and D* values between the two groups (P < 0.05). The three texture parameters SmallAreaEmphasis, Median, and Maximum had statistically significant differences between groups (P = 0.01, 0.004, 0.009, respectively). The logistic regression prediction model showed that D*, the median, and the maximum value were significant independent predictors, and the AUC of the regression prediction model was 0.860, which was significantly higher than other single parameters.

Conclusion: 3.0T MRI IVIM-DWI parameters combined with TA can provide valuable information for predicting the histological grades of rectal adenocarcinoma one week before the operation.

Case Report: A 38-year-old male presented to the emergency department with paroxysmal dysphasia for 6h. Brain magnetic resonance (MR) imaging showed acute cerebral infarction of the right corona radiata and right parietal lobe. Three-dimensional time-of-flight MR angiography (3D TOF MRA) revealed severe stenosis of the petrous segment (C1 portion) of the right internal carotid artery and a PTA originating from the right ICA cavernous segment (C4 portion), with a length of approximately 1.8cm and a diameter of approximately 0.2cm. The ICA segments are all named according to the Bouthilier classification. The basilar artery (BA) under union was well developed. The bilateral posterior communicating arteries were also present. One day later, the high-resolution vessel-wall MR demonstrated a dissecting aneurysm in the C1 portion of the right ICA. The length of the dissecting aneurysm is approximately 4.4cm, the diameter of the true lumen at the most severe stenosis is approximately 0.2cm, and the diameter of the false lumen is approximately 0.8cm. Subsequent digital subtraction angiography (DSA) confirmed a dissecting aneurysm in the C1 portion of the right ICA. The patient was treated conservatively and did not undergo interventional surgery. Four months later, head and neck MRA showed that the right ICA blood flow was smooth and that the dissecting aneurysm had disappeared.

The Ethics Committee of Liaocheng People’s Hospital approved the research protocol in compliance with the Helsinki Declaration. Written informed consent was obtained from the individual for the publication of any potentially identifiable images or data included in this article.

Conclusion: Flow alteration with PTA may have influenced the formation of ICA dissection in this patient. Awareness of this is crucial in clinical practice because it can influence treatment options and intervention procedures.

Objective: Here, we present a fetus with DSM by multiple imaging methods to help better understand the imaging characteristics of this malformation.

Case Presentation: A 22-year-old primipara was referred to our hospital at 25 weeks of gestation following the detection of a fetal intracranial mass without any symptoms. A prenatal ultrasound performed in our hospital at 25 ^{+ 2} gestational weeks showed a large anechoic mass with liquid dark space, while no blood flow was detected. After the initial evaluation, this primipara received a prenatal MRI in our hospital. This examination at 25 ^{+ 5} gestational weeks delineated a fan-shaped mass in the torcular herophili, which was iso-to hyperintense on T1WI and hypointense on T2WI. At the lower part of this lesion, a quasi-circular hyperintense on T1WI and a signal slightly hyperintense on T2WI could be seen. Meanwhile, the adjacent brain parenchyma was compressed by the mass.

Conclusion: We reviewed the current literature to obtain a better understanding of the mechanisms, imaging characteristics, and survival status of DSM. Although the primipara of the present study regretfully opted for elective termination of pregnancy, the reevaluation of DSM survival deserves more attention because of the better survival data from recent studies.

Objective: To describe the imaging characteristics of GCCMs and study the reasons for preoperative misdiagnosis.

Methods: We retrospectively analyzed the data of 12 patients (5 men, 7 women; mean age, 35.23 ± 12.64 years) with histopathologically confirmed GCCMs. Two radiologists analyzed the CT (n = 12) and MRI (n = 10) features: location, number, size, shape, boundary, signal intensity, and enhancement.

Results: The sellar region, cerebral hemisphere, skull bone, and ventricle were involved in 5, 4, 2, and 1 patients, respectively. Three tumors were irregularly shaped, while nine were oval. Eleven lesions showed slightly high- and/or high-density on CT; 1 lesion appeared as a low-density cyst. Calcifications were found in 11 lesions. Four tumors showed uniform hypointensity on T1-weighted imaging (T1WI) and hyperintense signals on T2-weighted imaging (T2WI). Six tumors showed mixed low-, equal-, and high-intensity signals on T1WI and T2WI. Noticeable contrast enhancement and gradual strengthening were noted on T1WI. Ten lesions showed hemorrhage and hemosiderin deposition. The GCCMs were wrongly diagnosed as cartilage-derived tumors/ meningioma (3 patients); tumor and hematoma (2 patients each); and pituitary tumor/ meningioma, chondroma, chordoma, ependymoma, and macroadenoma (1 patient each).

Conclusions: GCCMs present as an oval mass with slightly high- and/or high-density calcifications on CT and show hemorrhage and hemosiderin accumulation on MRI. Therefore, slightly high- and/or high-density calcification and hemosiderin accumulation are critical clinical characteristics of GCCMs.

Background: Over recent years, diagnostic imaging has progressed from a state of commencement to an advanced level. Numerous modern imaging procedures have evolved. Although contemporary medical imaging comprises image exhibition together with image refining, computer-aided diagnosis (CAD), image inscribing and conserving, and image transference, the majority of which are embraced in picture documentation and communication processes.

Aim: This review targets to encapsulate toxicology information on skin cancer unpredictability essential to interpretation measures, report important factor that helps in defining skin cancer condition, and possible medical care alternatives or medical attention endorsed referring to diverse aspects involving the size and site of malignancy, the complications, patient’s priority and well being. We concisely review various therapy alternatives, methods of radiation autoimmunity, prime observational study designs of medical and distinct radiation resources and cancer risks, and current analysis methodologies and research precision.

Conclusion: The detail of this paper covers a brief review of research and evolution in medical imaging discipline and mechanism. This review considers the physiology of melanocytes and the pathogenesis of skin cancer using medical imaging. Also, a description of risk factors, prevention methods, screening, various diagnosis methods and different stages of skin cancer, sub-types and different types of treatment methods is provided in this paper for research and development.

Objective: The objective of this study is to interpret the radiological findings of GCL and address the differential diagnosis between GCL and other lymphatic malformations in light of the relevant literature data.

Methods: The sample of this retrospective study consisted of six pediatric patients, four males and two females, diagnosed with GCL based on clinical, radiological, and histopathological findings between 2015 and 2022. The age of the patients at the time of diagnosis and their symptoms at admission were obtained from the hospital database. Radiological imaging findings were evaluated in detail based on the involved systems (thorax, abdomen, and musculoskeletal).

Results: The median age of the sample, 4/6 were male, was 9 years at admission (min. 3, max. 12). The most common symptom at admission was dyspnea, often accompanied by pleural effusion. Bone involvement was the most common extrathoracic finding. Abdominal involvement was primarily asymptomatic, and the spleen was the most frequently involved organ in the abdomen.

Conclusion: The diagnosis of GCL is challenging because of its rarity and overlapping diseases. Whole-body magnetic resonance imaging is a valuable tool as it reveals the typical radiological features of GCL and how far it has spread throughout the body.

Case Presentation: We report a 28-year-old man who was diagnosed 20 years ago with Klippel-Trenaunay syndrome. Approximately 3 years ago, he found enlarged masses on both upper extremities and a new dark red mass that was pathologically diagnosed as cavernous haemangioma appeared on the right index finger.

Conclusion: KTS is a rare and potentially multisystem disease requiring multidisciplinary management for which imaging examination is an important auxiliary diagnostic method. Various complications may occur during its development, so regular follow-up is required to prevent serious accidents.

Case Report: A 21-year-old male patient with a solitary kidney who had been diagnosed since birth presented with abdominal pain. Transabdominal and transrectal ultrasonography (US), computed tomography (CT), and MRI were performed. The contrast-enhanced MRI of the pelvis showed a tubular fluid-filled, macrolobulated lesion measuring 6 x 6 x 4 cm, mildly high signal intensity in the T2-weighted images, and slightly high signal intensity in the T1-weighted images, without contrast enhancement. The left kidney was hypoplasic. Imaging findings led to the diagnosis of Zinner’s syndrome, and conservative treatment was planned.

Discussion: Zinner’s syndrome is characterized by a triad consisting of unilateral renal agenesis or hypoplasia, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. MRI is the modality of choice for an impeccable depiction of the anatomy of the male genital tract, for demonstrating the seminal vesicles and evaluating anomalies of the mesonephric duct. It is also useful in distinguishing seminal vesicle cysts from other cystic pelvic masses.

Conclusion: Zinner’s syndrome should be considered when diagnosing cystic pelvic masses in males with renal agenesis or hypoplasia. Because of its high soft tissue contrast resolution, MRI is the gold standard modality for confirming the diagnosis and assessing the cyst’s origin and contents.

Case Summary: We report a 44-year-old woman with aggravated right hip pain during the past decade. The patient presented with severe pain and a functional disorder of the right hip. X-ray examination revealed severely narrowed right hip joint space and abnormal trabecular bone loss in the femoral neck and trochanter area. Doppler ultrasound, magnetic resonance imaging and computed tomography angiography revealed AVMs surrounding the right hip, along with erosion. To ensure the safety of THR, we performed vascular embolization and temporary balloon occlusion of the iliac artery three times during the operation. However, serious hemorrhage occurred, which was rescued by the multimodality blood conservation strategy. THR was successfully performed, and the patient was discharged 8 d later for rehabilitation. Postoperative pathological examination showed osteonecrosis of the femoral head with malformed thick-walled vessels and focal granulomatous inflammation of the surrounding soft tissues. The Harris Hip Scale score increased from 31 to 82 at 3 mo of follow-up. The patient was followed up for 1 year, and all her clinical symptoms were significantly alleviated.

Conclusion: Arthritis of the hip caused by AVMs is rare in clinical practice. The activity and function of the involved hip joint can be effectively treated with THR after comprehensive imaging and multidisciplinary consultation.

Core Tip: Arthritis of the hip caused by arteriovenous malformations is rarely reported. Total hip replacement (THR) is a reliable and effective option for the treatment of advanced arthritis of the hip. We report a 44-year-old woman with aggravated pain in the right hip during the past decade. With the vascular intervention and multimodality blood conservation strategy. THR can be successfully performed in patients with AVM-induced arthritis of the hip.

Methods: Literature review through a search in six electronic databases, structured in PICO format, without date restrictions. Looking for studies that used submaximal field walking tests in children and adolescents with congenital heart disease aged 5 to 18 years. Methodological quality, effectiveness and safety and risk of bias were assessed.

Results: Five studies met the eligibility criteria with a sample of 160 individuals with congenital heart disease, and all used the six-minute walk test. Note that different methodologies and modifications are used. Only the clinical trial showed good methodological quality.Four studies had low risk of bias and one study had moderate risk.

Conclusion: Although the six-minute walk test is the only test used as a field test found in our research, there is no standardization in the application of the test, making it difficult to compare the results. In this sense, reducing the limitations and heterogeneity in the application of the test will enable more concrete outcomes and facilitate their reproduction in clinical practice.

Objective: Here, we have analyzed a multicenter CCM cohort looking for the differential clinical data regarding the patients harboring supra and/or infratentorial cavernous malformations in order to better understand risk factors involved in the anatomical location of the unique neurosurgical disease.

Methods: We have presented a multicenter, Propensity Score Matched (PSM), case-control study including 149 consecutive CCM cases clinically evaluated from May 2017 to December 2022 from three different neurosurgical centers. Epidemiological data were defined at each clinical assessment. Logistic regression was used to identify the independent contribution of each possible risk factor to the bleeding risk. To balance baseline covariates between patients with and without symptoms, and specifically between those with and without symptomatic bleeding, we used a PSM strategy. The Kaplan-Meier curve was drawn to evaluate if patients with infratentorial lesions had a greater chance of bleeding earlier in their life.

Results: The presence of infratentorial lesions was a risk factor in the multivariate analysis comparing the bleeding risk with pure asymptomatic individuals (OR: 3.23, 95% CI 1.43 – 7.26, P = 0.005). Also, having an infratentorial CCM was a risk factor after PSM (OR: 4.56, 95% CI 1.47 - 14.10, P = 0.008). The presence of an infratentorial lesion was related to precocity of symptoms when the time to first bleed was compared to all other clinical presentations in the overall cohort (P = 0.0328) and in the PSM group (P = 0.03).

Conclusion: Here, we have provided some evidence that infratentorial cerebral cavernous malformation may have a more aggressive clinical course, being a risk factor for symptomatic haemorrhage and precocity of bleeding.

Methods: The prepared library of compounds underwent comprehensive assessment for their biological activities, encompassing antioxidative, antiproliferative, and antibacterial properties, in addition to in vivo toxicity evaluation using a Zebrafish model. Compound 4i, which consists of a retinoic acid moiety, exhibited the strongest scavenging activity against ABTS radicals (IC₅₀ = 36 ± 2 μM). In addition, 4b and some of the analogues (4a, 4c and 4i), mostly containing an unsaturated chain and conjugated double bonds, showed moderate but non-selective activity with certain IC₅₀ values in the range of 20-40 μM.

Results: In contrast, the analogue 4l, a derivative of alpha-linolenic acid, was the least toxic towards normal cell lines. Moreover, 4b was also highly active against Gram-positive Bacillus subtilis with an MIC of 125 μM. Nevertheless, both 4b and 4i, known for the best-observed effects, caused remarkable developmental abnormalities in the zebrafish model Danio rerio.

Conclusion: Since modification of the side chain did not significantly alter the change in biological activities compared to the parent compound, granulatamide B (4b), the substitution of the indole ring needs to be considered. Our group is currently carrying out new syntheses focusing on the functionalization of the indole core.

The present review aims at summarizing the different clinical conditions presenting with rectal bleeding in infancy and provides an evidence-based diagnostic work-up for the clinical management of patients with this occurrence.

Objectives: An attempt has been made to summarise the prenatal interventions, if available, the optimal route, mode and time of delivery and discuss the minimum delivery room preparations that should be made if expecting to deliver a fetus with a congenital anomaly.

Methods: The recent literature related to the perinatal management of the fetus with prenatally detected common congenital anomalies was searched in English peer-reviewed journals from the PubMed database to work out an evidence-based approach for their management.

Results: Fetuses with prenatally detected congenital anomalies should be delivered at a tertiary care centre with facilities for neonatal surgery and paediatric intensive care if needed. There is no indication for preterm delivery in the majority of cases. Only a few congenital malformations, like highrisk sacrococcygeal teratoma, congenital lung masses with significant fetal compromise, fetal cerebral lesions or neural tube defects with Head circumference >40 cm or the biparietal diameter is ≥12 cm, gastroschisis with extracorporeal liver, or giant omphaloceles in the fetus warrant caesarean section as the primary mode of delivery.

Conclusion: The prognosis of a fetus with congenital anomalies can be significantly improved if planning for delivery, including the place and time of delivery, is done optimally. A multidisciplinary team should be available for the fetus to optimize conditions right from when it is born.

Case Report: In this case study, a patient in her 90s with a suspected peripheral arterial disease, which required an angiotomography of the lower limb, showing a superficial femoral artery running to the middle and distal third of the thigh and a vascular structure running in the sciatic neurovascular bundle corresponding to a persistent sciatic artery presenting atherosclerotic changes and extensive occlusion, was presented. The patient's treatment was clinical with dual antiplatelet therapy and prophylactic anticoagulation. This was due to comorbidities and age. Moreover, the PSA occlusion was not critical and did not significantly impact the patient's quality of life.

Conclusion: Most patients with this anatomical variant are asymptomatic all their lives, but some of them may present symptoms with serious consequences. It is important to suspect it by clinical presentation and perform diagnostic confirmation by angiotomography. Treatment has yielded excellent results with endovascular techniques. Certain patients only require conservative treatment with anticoagulants and antiplatelet agents.

Introduction: Zn²⁺-containing endo-type peptidases directly degrade and remodel the ECM region in the progression of various diseases. MMPs are frequently found in abnormal disease status of inflammatory responses, periodontal lesion, inflammatory pulmonary lesion, arteriosclerotic smooth muscles, arthritis, and tumor metastasis and invasion. They are also known to participate in aging processes-such as wrinkle formation-by destroying collagen in the dermis. In particular, the onset of diseases via the MMP-dependent inflammatory response is caused by the breakdown of proteins in the ECM and the basement membranous region, which are the supporting structures of cells.

Methods: This review describes the developments in the research examining the general and selective inhibitors for MMP associated with various human diseases over the past 20 years in terms of structure remodeling, substrate-recognizing specificities, and pharmacological applicability.

Results: Among two similar types of MMPs, MMP-2 is known as gelatinase-A with a 72 kDa, while MMP-9 is termed gelatinase-B with a 92 kDa. Both of these play a key role in this action. Therefore, both enzymatic expression levels coincide during the onset and progression of diseases. Endogenous tissue inhibitors of matrix metalloproteinases (TIMPs) are highly specific for each MMP inhibitor type. The intrinsic factors regulate various MMP types by inhibiting the onset of various diseases mediated by MMP-dependent or independent inflammatory responses. The MMP- 9 and MMP-2 enzyme activity related to the prognosis of diseases associated with the inflammatory response are selectively inhibited by TIMP1 and TIMP2, respectively. The major pathogenesis of MMP-mediated diseases is related to the proliferation of inflammatory cells in various human tissues, which indicates their potential to diagnose or treat these diseases. The discovery of a substance that inhibits MMPs would be very important for preventing and treating various MMP-dependent diseases.

Conclusion: Considerable research has examined MMP inhibitors, but most of these have been synthetic compounds. Research using natural products as MMP inhibitors has only recently become a subject of interest. This review intends to discuss recent research trends regarding the physiological properties, functions, and therapeutic agents related to MMPs.

Objective: Various approaches have been developed over the years aiming to attain either a safer or faster brain delivery; a nasal delivery system proposes significant outcomes. The noninvasiveness and high vascularity contribute to the high permeability of the nasal mucosa, allowing rapid drug absorption. This review highlights some promising novel approaches to efficiently deliver anti-epileptic drugs by employing the nasal route.

Methods: The method includes a collection of data from different search engines like PubMed, ScienceDirect and SciFinder for obtaining appropriate and relevant literature regarding epilepsy, intranasal delivery of anti-epileptic agents, and novel therapeutics.

Results: The present review underlines the majority of work related to intranasal delivery in the treatment of epilepsy, aiming to draw the attention of the researchers towards the easiest and most efficient ways of formulation for the delivery of anti-epileptics during seizures.

Conclusion: This review intends to provide an understanding of the delivery aspects of antiepileptic drugs, the benefits of intranasal delivery and the novel approaches employed for the treatment of epilepsy.

Method: A total of 17 patients with reported hepatic hemangiomatosis between 2015 and 2017 were identified retrospectively. All our patients underwent pre-contrast MRI, triphasic (atrial, portal, venous) Gd-EOB-DTPA dynamic enhancement and hepatobiliary phase (20 minutes delayed). The location, size, morphology and signal characteristics on T1-weighted (T1WI) and T2-weighted images (T2WI), and Gd-EOB-DTPA-enhanced MRI of liver hemangiomatosis were evaluated.

Results: Hemangiomatosis involved the liver adjacent to the edge of the GCH with no normal liver tissue found in 13 cases; in the other 4 patients, a small area of normal liver tissue separated GCH from hemangiomatosis was seen. On non-contrast MRI images, hemangionmatosis presented as numerous microcystic lesions, with low signal intensity on T1WI and high signal intensity on T2WI, compared with unaffected liver. After administration of Gd-EOB-DTPA, heterogeneous enhancement was presented in the arterial phase, during portal and venous phase imaging, becoming more homogeneous. 11 cases showed hypointensity in the hepatobiliary phase (6 cases with intratumor necrosis), and 6 cases showed hyper-intensity in the hepatobiliary phase with a remaining unfilled portion.

Conclusion: Hemangiomatosis is extremely rare in the liver adjacent to a GCH. MRI is of great diagnostic and clinical value for this kind of tumor according to the configuration, size, signal, and style of enhancement, but the final diagnosis depends on pathology. Gd-EOB-DTPA-enhanced MRI may help in diagnosing hemangiomatosis coexistent with GCH.

Objective: To demonstrate the mechanism of As₂O₃ restraining lung cancer growth and metastasis by blocking the calcineurin-NFAT pathway by upregulating DSCR1.

Methods: We constructed xenografts and metastasis models based on wild-type (WT) and DSCR1 knockout (DSCR1-/-) mice, and carried out qPCR, Western blot, immunohistochemistry, in vivo imaging and calculated microvessel density to evaluate the effects of As₂O₃ on angiogenesis, tumor growth, metastasis, and the protein expression levels of DSCR1 and calcineurin-NFAT pathway-related molecules.

Results: As₂O₃ inhibited tumor growth and metastasis, reduced microvessel formation, and induced vascular lumen malformation in WT mice. At the protein level, As₂O₃ upregulated DSCR1, downregulated NFAT2 and its downstream molecules, but had no effect on calcineurin A. However, in DSCR1-/- mice, the above-mentioned effects of As₂O₃ were abolished.

Conclusion: As₂O₃ can suppress lung cancer growth and metastasis through anti-angiogenesis effects by blocking the calcineurin-NFAT pathway by upregulating DSCR1. The results shed light on the antitumor mechanism of As₂O₃ and are a step forward in the identification of As₂O₃ as a new drug in the treatment of lung cancer.

Methods: We retrospectively evaluated 20 patients; 10 GBM as the malignant group, 5 CM and 5 DVA as the benign group. Ktrans, Kep, Ve, and IAUC parameters were measured by DCE-MRP, within the lesion, at perilesional nonenhancing white matter (PLWM) and contralateral normal appearing white matter (CLWM).

Results: All benign and malignant lesions exhibited significantly increased Ktrans, Ve, and IAUC values compared to PLWM and CLWM (p < 0.001, p=0.006 and p<0.001). Subtracted Kep values between lesion and PLWM were significantly different between the benign and malignant groups, as the malignant group exhibited higher subtracted Kep values (p 0.035). For the malignant group; Ktrans and IAUC values at the lesion were positively correlated (r 0.911), while Kep and Ve at CLWM were negatively and strongly correlated (r 0.798). For the benign group; Ktrans with Ve and Ktrans with IAUC at lesion (r 0.708 and r 0.816 respectively), Ktrans and IAUC at PLWM (r 0.809), Ktrans and IAUC at CLWM(r 0.798) were strongly and positively correlated. Ktrans, Ve, and IAUC values can be used to restrict the lesion in both groups.

Conclusion: Ktrans strongly correlates with IAUC and they can be used instead of each other in both benign and malignant lesions. Classical DCE-MRP parameters cannot be used in the differentiation of malignant lesions from benign vascular lesions. However, subtracted Kep values can be used to differentiate GBM from benign vascular lesions.

Methods: We conducted a meta-analysis to assess the effects of LISA when compared to the socalled intubation-surfactant-extubation (INSURE) and the standard endotracheal intubation and mechanical ventilation (MV). The primary outcome was the composite incidence of death or bronchopulmonary dysplasia at a postmenstrual age of 36 weeks. The secondary outcome was the composite incidence of seven other severe adverse events. On 06 October 2021, we searched randomized clinical trials (RCTs) in PubMed, the Cochrane Library, ClinicalTrials.gov, and the ICTRP Registry.

Results: We included 18 RCTs. The pooled data on the primary outcome favored LISA when compared to either INSURE (risk ratio 0.67; 95% CI, 0.51 to 0.88) or MV (risk ratio 0.78; 95% CI, 0.61 to 0.99). The pooled data on the second outcome also favored LISA when compared to INSURE (risk ratio 0.75; 95% CI, 0.60 to 0.94) and MV (risk ratio 0.73; 95% CI, 0.55 to 0.96).

Conclusion: The findings showed that surfactant application by non-intubation respiratory support and the use of a thin catheter may decrease the composite risk of death or bronchopulmonary dysplasia. The included data support the view that LISA should be considered the preferred treatment option in eligible infants.

Methods: Authors searched PubMed/MEDLINE, ISI-web of knowledge, and Google scholar databases for medical subject headings terms and free-text words related to the classes mentioned above of chemicals and bone metabolism and remodeling for better clarifying and understanding the main mechanisms of bone disruption.

Results: Several EDCs act as xeno-estrogens. Considering that estrogens play a significant role in regulating bone remodeling, most of these chemicals generate hormonal imbalance with possible detrimental consequences on bone tissue structure and its mechanical and non-mechanical properties.

Discussion: Much evidence about bone disruptors was obtained from in vitro studies or animal models with equivocal results. Besides, a few data have been acquired from humans, and most of these data focused on the impact of EDCs on bone mineral density without considering their influence on long-term fracture risk. Moreover, humans may be exposed to a mixture of EDCs, and the final effect on bone metabolism might be attributable to either synergistic or antagonist effects. Age of first exposure, cumulative exposure over time, and the usually observed non-monotonic dose-response curve for EDCs should be considered as other essential variables influencing bone metabolism's final effect.

Conclusion: Given these variables, observational studies are needed to analyze this issue for ecological purposes better and preserve bone health.

Objective: This paper presents a review of the principal features of the tumors involving the genitourinary tract in children and an update in genetic background, diagnosis, and treatment.

Methods: A narrative review was performed on published literature about genitourinary tract tumors in pediatric patients. Papers presented in English and Spanish literature were reviewed. PubMed, Science Direct, and SciELO databases were used to collect information and present this article.

Results: Kidney tumors are the most common type of genitourinary tumors in children. Among those, Wilms tumor represents the majority of cases and shows the successful work of clinical trial groups studying this tumor type. Other tumors involving the genitourinary tract in children include Rhabdomyosarcoma, Transitional cell carcinoma, Testicular, and Adrenal tumors.

Conclusion: Genitourinary tract tumors in children represent significant morbidity and economic burden, so awareness in early diagnosis represents improvement in treatment, clinical, and oncological outcomes.

Objective: To report the clinical presentation, the first- and second-line treatment and outcomes of UNSEPs.

Methods: We retrospectively collected patients treated for UNSEP (namely cervical, interstitial, ovarian, angular, abdominal, cornual and intramural), their baseline characteristics, risk factors, symptoms, diagnostic pathway and the type of first-line treatment (medical, surgical or combined). We further collected treatment failures and the type of second- line treatment. We assessed treatment outcomes, time to serum beta human chorionic gonadotropin (β-hCG) level negativity, length of recovery, follow up and return to a normal menstrual cycle.

Results: From 2009 to 2019, we collected 79 cases. Of them, 27 (34%), 23 (29%), 12 (15%), 8 (10%), 6 (8%) and 3 (4%) were cervical, interstitial, ovarian, angular, abdominal and cornual, respectively. Forty women (50.6%) were submitted to medical treatment, mostly methotrexate based; conversely, 36 patients (45.6%) underwent surgery and only 3 women (3.8%) received a combined treatment. The success of first-line treatment rate, regardless of UNSEP location, was 53% and 89% for medical and surgical treatment, respectively. Treatment failures (21 patients) were submitted to second-line treatment, respectively 47.6% and 52.4% to medical and surgical approach. Of interest, cervical pregnancies achieved the lowest rate of first-line medical treatment success (22%) and received more frequently (69%) a subsequent surgical approach with no hysterectomy. Interstitial pregnancies were submitted to surgery mostly for a matter of urgency (71%), otherwise, they were treated with a medical approach both at first- and second-line treatment. Ovarian pregnancies were treated with ovariectomy in 44% of the cases submitted to surgery. Angular pregnancies underwent surgery more often, while all the abdominal pregnancies underwent endoscopic or open surgery. Cornual pregnancies received cornuostomy in 75% of the cases. Overall, the need for blood transfusion was 23.1% among the patients submitted to surgery. The median length of hospitalisation was shorter for women submitted to surgical first-line treatment (5 vs. 10 days; p = 0.002). In case of first-line medical treatment and in case of failure, we found an increase of 3 days (CI95% 0.6-5.5; p = 0.01) and of 3.6 days (CI95% 0.89-6.30; p = 0.01) in the length of hospitalisation, respectively. Negative β-HCG levels were obtained earlier in the surgical group (median 25 vs. 51 days; p = 0.001), as well as the return to normal menstrual cycle (median 31 vs. 67 days; p < 0.000). Post-treatment follow-up, regardless of the failure of first-line treatment was shorter in the surgical group (median 32 versus 68 days; p= 0.003).

Conclusion: Cervical pregnancies were successfully managed with a surgical approach without hysterectomy, and hence, we suggest avoiding medical treatment. No consensus emerged for other UNSEPs. Ovarian, angular and interstitial pregnancies are burdened by a non-conservative approach on the utero-ovarian structures. The surgical approach led to shorter recovery, earlier β-hCG negativity and shorter follow-up, even though there is an increased risk for blood transfusion.

Objectives: The aims were (1) to identify the health issues encountered by women aged 16-45 years living with T2DM; (2) to determine the modifiable risk factors associated with living with diabetes; (3) to specify ideas for interventions to meet age and gender-specific diabetes-related healthcare needs.

Methods: A systematic search was performed in the following databases; MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science, and Maternity and Infant Care. Databases were searched without time and study design limits. The Mixed Methods Appraisal Tool was used to assess the methodological quality of included studies. Data were narratively synthesised due to mixed methods evidence included.

Results: A total of 32 papers were included in the review from which six domains were identified from the synthesis: (1) diabetes related modifiable risk factors: blood glucose, cardiovascular risk, neuropathy/nephropathy/retinopathy, diabetes self-management barriers (2) reproductive health: diabetes care before pregnancy, pre-pregnancy care barriers and expectations of women, contraceptive use (3) psychosocial wellbeing: depression symptoms and diabetes distress, perception of T2DM, emotional concerns about pregnancy (4) sexual function; (5) menopause; (6) sociocultural factors: social support, cultural norms.

Conclusion: This review highlighted specific health issues affecting women of reproductive age with T2DM and which represent an important focus for health services research and health care delivery. Future research needs to address identified health domains to improve women’s health and well-being living with T2DM.

Objective: The study aims to describe, through an integrative review, the physiopathology and aetiologies of HOCF and to discuss phenotypes associated with this condition.

Methods: Revisions, guidelines, case-controls, cohort studies and clinical studies were searched in MEDLINE and LILACS, using the connectives in the “cardiac output, high” database (MeSH Terms) OR “high cardiac output” (All Fields).

Discussion: Two distinct phenotypes are currently described in the HOCF, regardless of the aetiology: 1) one with enlarged cardiac chambers; and 2) with normal heart chambers. The mechanisms related to HOCF are vasodilation, arteriovenous shunts that cause increased microvascular density, Reduced Systemic Vascular Resistance (RSVR), and high metabolism. These mechanisms lead to activation of the renin-angiotensin-aldosterone system, sodium and water retention, activation of neprilysin, of the sodium-glucose-2 transporter, which promote interstitial fibrosis, ventricular remodeling and a consequent increase in cardiac output >8L/min.

Conclusion: Many aetiologies of HOCF have been described, and some of them are potentially curable. Prompt recognition of this condition and proper treatment may lead to better outcomes.

Significant variability of clinical manifestations as well as prolonged progress of the disease often cause errors in diagnosis. What follows is a case report of a young patient with Cobb Syndrome, who was admitted to a regional vascular centre with a misdiagnosis of stroke.

20 patients of young age (from 20 to 35 years old), with a diagnosis of stroke, who were admitted to a University Clinic (of the Russian National Research Medical University Named After Pirogov N.I., Moscow). Among this group of patients, a patient with Cobb syndrome was identified. Patient P., of 22 years, presented with acute, intensive cervical spinal pain, predominantly on the right, numbness and weakness in the arms and legs. About 3 weeks before admission to the hospital, the patient had ARVI with a fever of up to 37.5°C: two weeks before the onset of symptoms, he had undergone extirpation of 2 teeth, for which reason he spent over 2 hours in a forced position with his head thrown back (prolonged overextension in the cervical spine). Multiple skin angiomas on the chest spreading to the shoulder and scapula region. Tetraparesis up to 4 points: tetraparesis in hands with low muscle tone, low reflexes, tetraparesis in legs with high muscle tone, high reflexes, foot clonus when causing Achilles reflexes, tremor in the extremities and no plantar reflex pathology were detected, sensitivity disorders in the hands “the high gloves” and no pelvic disorders were detected. Given the presence and exacerbation of neurological symptoms and cutaneous angiomas, MRI with a contrast agent of the cervical spine was recommended. MR-image of an advanced arteriovenous malformation (AVM) of the cervical spinal cord with signs of gliosis and spinal cord oedema at the C2-C7 level. Endovascular embolization of the AVM in the cervical spinal cord was performed. The treatment led to the complete reversal of neurological symptoms. In the presence of skin lesions, the diagnosis of CS does not present particular difficulties, so in children and young patients with skin angiomatosis, it is advisable to conduct a comprehensive examination using selective spinal angiography or MR angiography to exclude arteriovenous malformations in the spinal cord.

Case Report: In this case report, the patient experienced severe headache with nausea, vomiting, and blurred vision for 12 days, and had a history of hypertension. Physical examination revealed a clear state of mind, normal speech, normal limb muscle strength, 2 transverse fingers of neck stiffness, and negative bilateral Babinski signs. Brain CT, MRI, MRA, and MRV showed no obvious abnormalities. SWI suggested the possibility of capillary dilation. The cerebrospinal fluid was pale yellow in appearance after lumbar puncture.

Diagnosis: The patient was diagnosed with subarachnoid hemorrhage (SAH) and capillary dilatation.

Interventions: Therapeutic management of blood pressure and brain edema was started.

Conclusion: Lumbar puncture should be performed when subarachnoid hemorrhage is clinically suspected and CT is negative. While searching for the cause of subarachnoid hemorrhage, the presence of telangiectasia should be ascertained.

Objective: The purpose of this study is to investigate the relationship of the KEAP-1/NRF-2/HO-1 pathway, one of the main regulators of the antioxidant system in the hydrocephalus pathology, on oxidative stress and tau protein level.

Methods: The study included 32 patients with hydrocephalus and 32 healthy controls. KEAP-1, NRF-2, HO-1, TAU, and MPO levels are measured using ELISA method TAS, TOS, and Total THIOL colorimetric method.

Results: KEAP-1, TAS, and Total THIOL levels were found significantly lowerer in the hydrocephalus group than in the control group. Nevertheless, it was identified that in the hydrocephalus group that the NRF-2, HO-1, TAU, MPO, TOS, and OSI levels were significantly elevated.

Conclusion: In conclusion, although the KEAP-1/NRF-2/HO-1 pathway is activated in patients with hydrocephalus, it is identified that the antioxidant defense system is insufficient and ultimately leads to elevated oxidative stress. The elevation in the tau level may be an indicator of oxidative stress induced neurodegenerative damage.

Methods: In this study, the role of ALMS1-IT in regulating neuro-inflammation and functional recovery was investigated after ischemic cerebral damage. To this end, the rat model of transient middle cerebral artery occlusion (tMCAO) was constructed, the cell model of oxygen-glucose deprivation (OGD) was established using BV2 microglial cells, and the aberrant expression of ALMS1-IT1 was assessed in brain tissues. After ALMS1- IT1 knockdown through intrathecal injection of Lv-shALMS1-IT1, neuro-inflammatory response and functional tests including a modified neurological severity score (mNSS) and a foot-fault test were assessed.

Results: The level of ALMS1-IT1 was promptly enhanced at 12 hours (h) following MCAO, peaking at 48 h, and remaining high at day 14 compared to the sham group. Pro-inflammatory cytokines (IL-1β, IL-6, and TNF- α) were increased after MCAO, whereas ALMS1-IT1 inhibition suppressed the expression of IL-1β, IL-6 and TNF-α in MCAO rats. The results from mNSS and foot-fault test showed that ALMS1-IT1 knockdown significantly improved spatial learning and sensorimotor function of MCAO rats. Mechanistically, ALMS1-IT1 knockdown suppressed the activation of NF-κB signaling in vitro and in vivo, as evidenced by decreased p65 expression and p65 nuclear translocation. ALMS1-IT1 overexpression facilitated pro-inflammatory cytokines expression in microglia, whereas the effect was blocked by treatment with JSH-23 (a specific NF-κB inhibitor).

Conclusion: These data demonstrated that ALMS1-IT1 inhibition improved neurological function of MCAO rats, at least in part by repressing NF-κB-dependent neuro-inflammation.

Methods: We searched Pub Med (132 articles) and Google scholar (9 articles) databases and gathered the clinical (4 articles), and preclinical (28 articles) studies, reports on cell culture models (30 articles), and other original and review articles (78 articles) related to inflammation, cancer, and cannabinoids.

Results: Cannabinoids are described in three different forms, comprising endo- phyto- and synthetic compounds that exert biological effects. The molecular and cellular pathways of endogenous cannabinoids in the maintenance of homeostasis are well documented. In addition to classical cannabinoid receptors type 1 and 2, Vanilloid receptors and G protein-coupled receptor 55 were identified as common receptors. Subsequently, the effectiveness of phyto- and synthetic cannabinoids mediated by cannabinoid receptors has been demonstrated in the treatment of inflammatory diseases, including neurodegenerative diseases as well as gastrointestinal and respiratory inflammations. Another accepted property of cannabinoids is their anti-cancer effects. Cannabinoids were found to be effective in the treatment of lung, colorectal, prostate, breast, pancreas, and hepatic cancers. The anti-cancer effects of cannabinoids were characterized by their anti-proliferative property, inhibition of cancer cell migration, suppression of vascularization, and induction of apoptosis.

Conclusion: The current review provides an overview of the role of the endocannabinoid system in the mediation of physiological functions and the type and expression of cannabinoids receptors under physiological and pathological conditions. In addition, the molecular pathways involved in the effects of cannabinoids and the effectiveness of cannabinoids in the treatment of inflammations and cancers are highlighted.

Objective: In this narrative review, we provide a comprehensive approach to experimental and clinical data regarding RAS molecule expression and their possible roles in the physiology and physiopathology of CNS diseases.

Methods: This non-systematic review summarizes evidence on RAS implications in CNS diseases and their possible relationships with COVID-19.

Results: We divided the possible RAS mechanisms in distinct conditions during the lifespan, approaching from congenital infections to neurodegenerative alterations, passing through mood disorders and cerebrovascular diseases. We also gathered current evidence about the possible effects of RAS in Covid-19, particularly in cases with neurological manifestations.

Conclusion: Although there are limitations and controversies, the analysis of RAS mechanisms in the CNS certainly represents an interesting field of research. However, further investigation is necessary to support the noteworthy interactions and provide a better comprehension of the cross-talk between RAS and the CNS. Investigations in this research field may shed light on the novel therapeutic targets.

This review aims at providing an overview of preclinical and clinical pieces of evidence supporting the possible role of gut-brain axis modulation in physiological aging, in a neurodevelopmental disorder, the autism spectrum disorders and in a substance abuse disorder, the alcohol addiction.

Since the normalization of gut flora can prevent changes in the behavior, we postulate that the gutbrain axis might represent a possible target for pharmacological and dietary strategies aimed at improving not only intestinal but also mental health. The present review also reports some regulatory considerations regarding the use of probiotics, illustrating the most debated issues about the possibility of considering probiotics not only as a food supplement but also as a “full” medicinal product.

We think that as long as there are no stable and serious results ofclinical and radiological findings of the patient, the patient should be approached with medical follow-up without treatment.

Methods: A sample of 71 amnestic MCI patients (age 74 ± 7.3 years, Mini Mental State Examination 24.2 ± 5.3) underwent cerebral [¹⁸F]Florbetaben PET/CT. Images were visually scored as positive or negative independently by three certified readers blinded to clinical and neuropsychological assessment. Amyloid positivity was also assessed by semiquantitative approach by means of a previously published threshold (SUVr ≥ 1.3). Fleiss kappa coefficient was used to compare visual analysis (after consensus among readers) and semi-quantitative analysis. Statistical significance was taken at P<0.05.

Results: After the consensus reading, 43/71 (60.6%) patients were considered positive. Cases that were interpreted as visually positive had higher SUVr than visually negative patients (1.48 ± 0.19 vs 1.11 ± 0.09) (P<0.05). Agreement between visual analysis and semi-quantitative analysis was excellent (k=0.86, P<0.05). Disagreement occurred in 7/71 patients (9.9%) (6 false positives and 1 false negative). Agreement between the two analyses was 90.0% (18/20) for SUVr < 1.1, 83% (24/29) for SUVr between 1.1 and 1.5, and 100% (22/22) for SUVr > 1.5 indicating lowest agreement for the group with intermediate amyloid burden.

Conclusion: Inter-rater agreement of visual analysis of amyloid PET images is high. Agreement between visual analysis and SUVr semi-quantitative analysis decreases in the range of 1.1< SUVr <=1.5, where the clinical scenario is more challenging.

Case: A full-term newborn girl delivered with a huge scalp defect. The dura mater was exposed but intact and there was no Cerebrospinal Fluid (CSF) leakage. She also had bilateral talipes equinovarus and terminal reduction of multiple toes in the left foot. Genetic testing was positive for Adam Oliver Syndrome. Conservative medical management was initiated at birth and continued until discharge at 4 weeks of age. The patient had a regular follow-up with plastic surgery and neurosurgery teams. At 11 months old, the defect became smaller, hairless with good granulation tissue, but still soft and compressible.

Conclusion: Large scalp midline ACC is a rare, but potentially devastating disease when involved adjacent tissue. The choice of treatment is not straightforward and it is mainly based upon the size, depth, and the risk of pre and post-treatment complications. Conservative management still is an option with very complex ACC.

Case report: Here, the case of a 4-year-old boy showing elevated blood pressure with left ventricular hypertrophy leading to idiopathic MAS, who was successfully treated with percutaneous transcatheter renal angioplasty (PTRA) using an unusual, anterograde access, is reported.

Discussion and Conclusion: In children and adolescents, vascular malformations like MAS must be considered as a possible cause of hypertension. PTRA is a successful therapeutic strategy in children with severe renovascular hypertension. Anterograde access, using an axillary artery, can be a valid approach for PTRA when femoral access is difficult to achieve.

Methods and Results: In recent years, there are several studies to elucidate the molecular aspects based on mouse genetics by using a stress-induced mechanical load model. Chondrocyte hypertrophy, which is usually seen in growth plate chondrocyte, is also induced in articular cartilage and involved in the onset of osteoarthritis. Additionally, signal molecules involved in inflammatory cytokine and matrix proteinase are expected to be target molecules for the fundamental treatment of early osteoarthritis. Some additional signal molecules, transcription factors and compounds have been reported to be involved in cartilage homeostasis.

Conclusion: This review sheds light on the current status of various signal molecules for the management of osteoarthritis.

Conclusion: Herein, we review recent advances in single cellular studies of cardiovascular system and summarize new insights provided by single-cell RNA sequencing in heart developmental sciences, stem-cell researches as well as normal or disease-related working mechanisms.

Materials and Methods: Particularly, sonic hedgehog gene plays a versatile role in cellular homeostasis and can be a novel therapeutic target in the prevention of cardiovascular disorders. Further various sonic hedgehog modulators have been reported working as futuristic drug molecules in the modulation of cardiovascular dysfunctions.

Results: However, there was limited literature availability that has summarized the possible mechanism of targeting Sonic hedgehog signaling pathway.

Conclusion: Thus, the present review is aimed at exploring the role of targeting sonic hedgehog protein signaling and modulators as well as to enlighten that how targeting sonic hedgehog protein involves in the amelioration of atherosclerosis, ischemic heart diseases, vascular endothelial dysfunction, heart failure and congenital heart diseases.

Purpose: The objective was to evaluate the MRI findings of DVAs in the brain, to compare the prevalence of them between MS patients and control subjects, and to investigate the correlation of DVA-associated fluid-attenuated inversion recovery (FLAIR) hyperintensities and MRI-derived parameters between MS patients and control subjects having DVA.

Methods: Total 160 patients with a mean age of 45 ± 16 years who underwent multiparametric MRI including susceptibility-weighted imaging (SWI), diffusion-weighted imaging, 3D FLAIR, and contrast-enhanced imaging were included in this retrospective study. First, the presence of DVA was compared between the MS and control groups using the Chi-square test. Then, among the subjects having DVA, age, gender, and MRI-derived parameters such as the signal increase of DVA on FLAIR, location, and drainage of DVA were compared between the MS and control groups using Chi-square test.

Results: The presence of DVA did not differ between the MS and control groups (P = 0.828). Signal increase around DVA on FLAIR (P = 0.03) and the age of less than 45 years demonstrated a significant correlation with MS group (P = 0.022).

Conclusion: In our study, DVAs were effectively detected using SWI and 3D contrast-enhanced T1-weighted imaging on MRI. The signal increase of DVA was better revealed on 3D FLAIR on MRI, and it was the only significant MRI-derived parameter in patients with MS.
