Primary cardiac angiosarcoma: presenting with cardiac tamponade followed by cerebral hemorrhage with brain metastases.

ABSTRACT

A 49-year-old man presented with palpitation and shortness of breath. He was seen to have a massive pleural and pericardial effusion on radiography and echocardiography. Computed tomography (CT) scanning showed that cardiac tumors arose from the right atrium with epicardial and endocardial extension. Pathology examination of samples at pericardiotomy revealed them to be angiosarcoma. Two days after the surgery, he developed left hemiparesis. CT scans showed a large cerebral hemorrhage on the right temporal lobe with midline shift by brain metastases. He died 37 days after the surgery. At autopsy, he had metastases in the brain, multiple bones, and soft tissues but no lung or left-side heart involvement. Primary cardiac angiosarcoma is rare, and mostly arises from the right side of the heart. Common metastatic sites are the lungs and liver. There are only a few reports of brain metastases. In conclusion, this is a rare report of cardiac angiosarcoma presenting with pericardial tamponade. There were rapid brain and multiple bone metastases but no lung or left-side heart lesions.
