Summary

A 49-year-old woman was admitted to the hospital because of cardiac tamponade. The hemorrhagic pericardial effusion was cytologically negative for malignant cells. Cardiac magnetic resonance imaging showed two masses in the anterior and lateral right atrium; however, positron emission tomography (PET) image using ¹⁸F-fluorodeoxyglucose revealed strong uptake in the anterior right atrium, without other tumors or metastasis. Intraoperatively, the lateral mass was confirmed as a thrombus, whereas the anterior mass was removed surgically and was diagnosed as an angiosarcoma with histopathological examination. However, she was re-admitted to the hospital 1 month after the operation because of cerebral hemorrhage, suspicious of distant metastasis. PET is useful for the detection of cardiac angiosarcoma.
