Imaging findings
CT shows a large, necrotic mass arising from the right atrium and extending to the atrioventricular groove, with heterogeneous enhancement. Patient also had multiple small lung nodules, some with surrounding hemorrhage, consistent with metastases. MRI also showed the findings.
Key takeaways
Primary cardiac angiosarcoma is a rare but aggressive malignancy typically arising from the right atrium, often presenting as a large, necrotic, heterogeneously enhancing mass. It commonly metastasizes to the lungs, sometimes with associated hemorrhage.
