Abstract:
Background:
Secondary cardiac tumors are a rare disease that is hard to detect when the tumor is small and asymptomatic. This case report focuses on a massive
pulmonary metastasis filling almost the entire left atrium. Multimodal enhancement imaging, cardiac contrast-enhanced ultrasound (CEUS),
enhanced electron computed tomography, and positron emission tomography imaging were applied to detect the malignant origin of this case. The
aim of this project was to provide an important basis for clinical treatment and decision-making with multimodal imaging.
Case Presentation:
The patient was hospitalized with suspected to be a lumbar spine fracture. According to the multimodal imaging, pathologically confirmed to suffer
a cardiac metastasis from small cell lung cancer. EP-regimen (Etoposide 0.1gd 1-5+Nedaplatin 30mgd 1-4) was selected for the systemic
chemotherapy of the patient. During three years of follow-up, the left intra-atrial occupancy was significantly reduced.
Conclusion:
Multimodality imaging can cover up the deficiencies of single imaging examinations and further clarify and enrich the understanding of the
relationship between the location and the surrounding structure of the mass, thus providing a good reference for clinical treatment and decisionmaking.
