A case of cavernous hemangioma in which malignancy was preoperatively excluded by FDG-PET.
A contrast-enhanced mass was revealed by computed tomography and magnetic resonance imaging in the left pelvic cavity of a 71-year-old man. Although the mass appeared to be a cavernous hemangioma, malignancy could not be ruled out. Abdominal angiography was performed but failed to rule out malignancy because it revealed vascular dislocation and encasement. (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) was then performed, and suggested a benign tumor, with a standardized uptake value (SUV) of 1.7. Following this finding, because the tumor was large and rupture could not be ruled out, we decided to perform surgery. The resected tumor was a benign cavernous hemangioma, consistent with the result obtained by FDG-PET.
