摘　　要：目的总结卵巢卵泡膜细胞瘤(ovarian thecoma,OT)的MRI影像特征。方法回顾性分析12例OT患者的MRI影像资料。结果 12例MRI均表现为边界清晰的单侧卵巢肿块,3例呈类圆形,9例呈分叶状;实性肿块10例,囊实性肿块2例;平扫T1WI呈等信号9例,呈稍低信号3例;T2WI呈明显低信号2例,等低混杂信号9例,高信号1例;增强扫描示病灶实体部分呈轻度强化11例,明显强化1例;12例均伴少量盆腔积液。结论 OT的MRI表现具有一定特征性,有助于其诊断及鉴别诊断。Objective To investigate MRI imaging characteristics of ovarian theeoma （OT）. Methods The MRI findings were retrospectively analyzed in 12 patients with OT. Results MRI revealed unilateral ovarian mass with clear boundaries in 12 patients, oval shape in 3 and lobular in 9. In 12 patients, there were 10 solid masses and 2 cystic solid masses. Nine patients revealed isointense signal intensity and 3 revealed low signal intensity on T1WI. Two patients revealed low signal intensity, 9 revealed mixed isointense low signal intensity and 1 revealed high signal intensity on T2WI. Contrast enhancement scanning displayed mild enhancement in 11 patients and obvious enhancement in 1. All patients were complicated with small amount of pelvic effusion. Conclusion OT has typical MRI findings, which has an important value to the diagnosis and differential diagnosis of OT.
