title: Primary right atrial angiosarcoma misdiagnosed as aortic intramural hematoma.
abstract: The overall incidence of cardiac tumor is very low, and malignant cardiac tumors account for only 25% of all cardiac tumors. Angiosarcomas are the most common type of malignant cardiac tumors, characterized by rapidly proliferating, extensively infiltrating anaplastic cells derived from blood vessels and lining irregular blood-filled spaces. We present a 26-year-old man with angiosarcoma involving the right atrium, which was misdiagnosed as aortic intramural hematoma by computed tomography, finally confirmed by transesophageal echocardiography during the operation.
