CTICasesRight Ventricular Metastasis of Epithelioid Sarcoma
Imaging findings
CT chest shows a large, lobulated filling defect in the right atrium and right ventricle. Comparison with abdominal imaging shows contiguous extension from a primary pelvic epithelioid sarcoma invading the iliac veins and inferior vena cava (IVC) to reach the right heart.
Key takeaways
Epithelioid sarcoma and other aggressive pelvic malignancies can demonstrate hematogenous dissemination via contiguous venous invasion. The tumor thrombus propagates through the IVC directly into the right atrium and ventricle, mimicking a primary cardiac tumor or a massive saddle embolus.
