Successful treatment of primary cardiac angiosarcoma with docetaxel and radiotherapy.

A 49-year-old man was admitted for primary cardiac angiosarcoma with a cardiac tamponade. Transthoracic echocardiography and contrast-enhanced computed tomography scan demonstrated a large mass in the right atrium and thickening of the right ventricular wall. 18F-labeled deoxyglucose (FDG) positron emission tomography (PET) scan showed increased FDG uptake in the mediastinum and over the heart.
