title: FDG PET/CT of a benign ovarian Brenner tumor.
abstract: We present a case of an ovarian benign Brenner tumor identified in an 85-year-old woman. During an observation period of over 1 year, the tumor increased in size and showed newly appeared solid component. Magnetic resonance imaging was typical of a Brenner tumor; fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings revealed mild FDG uptake and calcification in the solid component. These findings of PET/CT are often found in ovarian mucinous carcinomas. Our case suggests that magnetic resonance imaging is superior to FDG PET/CT for the differential diagnosis of ovarian Brenner tumors from other malignant tumors.
