目的 探讨卵巢Sertoli-Leydig细胞瘤的影像表现及临床特征,以提高对该肿瘤的认识及诊断水平.材料与方法 搜集经病理证实的3例卵巢Sertoli-Leydig细胞瘤的CT、MRI影像资料,观察病变的影像学特征,并分析病变的影像学特征与预后的关系.结果 3例患者(17岁,71岁,58岁)共发现3个肿瘤,其中2例位于左侧卵巢,1例位于右侧卵巢,病变于CT、MRI均表现为边界清楚的实性或囊实性肿块,实性部分于T2WI呈等或稍高信号,囊性部分多位于实性部分内部,呈T2WI高信号,DWI病变呈高信号.增强扫描,病变实性部分呈明显强化.3例患者中有2例雄激素水平升高,临床呈男性化表现.结论 卵巢Sertoli-Leydig细胞瘤有一定的影像学特征,若发现卵巢实性或以实性成分为主的囊实性肿瘤,且实性成分于T2WI呈等或稍高信号时,结合患者临床病史,应考虑到该肿瘤的诊断.%Objective: To evaluate the clinical and imaging features of ovarian Sertoli-Leydig cell tumors (SLCTs) to improve the understanding and diagnosis accuracy of this kind of tumor. Materials and Methods: Retrospectively studied the images and clinical data of three ovarian SLCTs which confirmed by pathology and evaluated the relationship between imaging features and clinical information. Results: We totally find three tumors in three patients (17 ys, 71 ys and 58 ys), two on the left ovary and the other on the right side. All the tumors have the appearance of solid mass or solid and cystic mass with clear margin. The solid part of the tumor shows isointensity or slightly high intensity on T2WI and hypointensity on T1WI while the cystic part inner the solid lesion shows hyper intensity on both T2WI and DWI. After contrast, the solid part shows obvious enhancement. Two of three patients show elevated testosterone and present with symptoms of masculinization. Conclusions: There are some specific imaging features of ovarian SLCTs. According to clinical history, ovarian tumors with solid or main solid components which show isointensity or slightly high intensity on T2WI should be considered to the diagnosis of SLCTs.
