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.
我们报告了一例 85 岁女性的卵巢良性 Brenner 肿瘤。在超过 1 年的观察期内，肿瘤增大并出现新的实性成分。磁共振成像（MRI）表现典型的 Brenner 肿瘤；氟-18 氟代脱氧葡萄糖（FDG）正电子发射断层扫描（PET）/计算机断层扫描（CT）显示实性成分有轻度 FDG 摄取和钙化。这些 PET/CT 的发现常存在于卵巢黏液性癌中。我们的病例提示 MRI 对于卵巢 Brenner 肿瘤与其他恶性肿瘤的鉴别诊断优于 FDG PET/CT。
