CTICasesCardiac Angiosarcoma
Imaging findings
CT scans from two different cases show large, infiltrative, necrotic masses in the right atrium and atrioventricular groove. Unlike the cardiac lymphoma case, both demonstrate hypervascular feeding branches arising from a dilated right coronary artery, disorganized internal vessels, and associated pulmonary metastases.
Key takeaways
Cardiac angiosarcomas are primary malignant vascular tumors that typically involve the right atrium and right atrioventricular groove. They are classically hypervascular, frequently recruiting blood supply from a dilated right coronary artery, which helps distinguish them from lymphoma.
