【摘要】 目的 探讨卵巢Sertoli-Leydig细胞瘤（SLCTs）的MRI表现特点。方法 回顾性分析7例手术病理证实为卵巢SLCTs的临床、MRI表现及病理资料。结果 7例卵巢SLCTs患者中，5例出现睾酮水平升高。MRI表现为实性肿块伴小囊变区或囊实性肿块伴厚薄不均囊壁、分隔及壁结节；实性部分在T₁WI呈低信号，T₂WI呈稍高信号；囊性部分在T₁WI呈低信号，T₂WI呈高信号；增强扫描显示病灶内实性部分、分隔及壁结节明显强化。结论 卵巢SLCTs MRI表现为实性或多房囊实性肿块，可具有不规则增厚囊壁和分隔，实性成分及分隔明显增强。更多还原

【Abstract】 Objective To investigate the MRI characteristics of ovarian Sertoli-Leydig cell tumors（SLCTs）.Methods The clinical, MRI features and pathological data of 7 cases with ovarian SLCTs confirmed by operation and pathology were analyzed retrospectively.Results 5 out of 7 cases of ovarian SLCTs, showed elevated levels of testosterone.MRI characteristics of ovarian SLCTs were presented mainly as solid mass with small cystic area, cystic solid mass with uneven thickness of cystic wall, septa or mural nodules.The solid components appeared as low signal intensity on T₁WI and slightly high intensity on T₂WI,while the cystic components showed low signal intensity on T₁WI and high intensity on T₂WI.All the solid components and septa or mural nodules showed enhancement after administration of contrast medium.Conclusion MRI of ovarian SLCTs presents as solid or solid and multi-cystic mass with the irregularly thickened wall and septa, obvious enhancement in the solid and septa components.更多还原
