A 53-year-old asymptomatic woman was found to have a pelvic mass at medical examination. Magnetic resonance (MR) imaging revealed a 4-cm solid mass at the right adnexal region, which showed marked hyperintensity on T(2)-weighted imaging and marked enhancement on post-contrast T(1)-weighted imaging. Chemical-shift imaging showed slight but significant signal loss on out-of-phase images, which suggested the presence of intratumoral lipid. The resected specimen exhibited typical features of steroid cell tumor, and Oil Red O stain was positive for cytoplasmic lipid.
一位 53 岁无症状女性在体检时发现盆腔肿块。磁共振成像（MR）显示右侧附件区有一个 4cm 的实性肿块，T2 加权成像呈明显高信号，增强后 T1 加权成像明显强化。化学位移成像显示反相位图像上有轻微但显著的信号丢失，提示肿瘤内存在脂质。切除标本表现出类固醇细胞瘤的典型特征，油红 O 染色细胞质脂质阳性。
