Abstract

A 55-year-old woman underwent CT for abdominal distension, which incidentally revealed coronary sinus dilatation. The echocardiography showed a mass in the coronary sinus. Coronary CTA showed a slightly low-density mass in the coronary sinus without enhancement. Subsequently, contrast-Enhanced 18 F-FDG PET/MR was performed to exclude underlying malignancy, which revealed low uptake (SUVmax 2.5) and mild segmental heterogeneous enhancement in the tumor. Then the patient underwent surgery, and histopathologic examination revealed epithelioid hemangioendothelioma.
