CTICasesCardiac metastasis of sarcoma
Imaging findings
Contrast-enhanced chest CT shows a large, aggressive metastatic tumor mass within the right ventricle of the heart, filling approximately 90% of the right ventricular lumen, in a patient who previously underwent a pneumonectomy for a lower extremity sarcoma.
Key takeaways
Intracardiac metastases from sarcomas can grow to occupy almost the entire right ventricular lumen. Despite near-total obstruction of the right ventricle, blood flow can be maintained, allowing survival until hospice care.
