MRI diagnosis of young women's ovarian thecoma

目的提高对青年妇女卵巢卵泡膜细胞瘤MRI特征的认识。方法结合文献对3例经病理证实的青年妇女卵巢卵泡膜细胞瘤的MRI表现及临床特点进行回顾性分析,观察肿瘤形态、大小、边缘、信号及增强特征。结果 3例患者平均年龄32岁,肿瘤均单发,体积大,2例椭圆形、边界清楚,1例生姜状,边界欠清伴淋巴结肿大,3例均伴少量腹水,肿块实质性为主,T1WI瘤实质为等信号,T2WI呈稍低、等信号,增强轻-中度强化。结论青年妇女卵泡膜细胞瘤MRI表现有一定特征性,可提高对该病的认识,有助于减少误诊。

Objective To study MRI findings and diagnostic value for young women＇ s ovarian thecoma. Methods Three patients with ovarian thecoma confirmed by histopathology were reviewed retrospectively. MRI findings, including tumor shape, size, margin and sig- nals, were analyzed. Results The MRI showed that tumors were presented as the following features ： single in lesion, large size, ellipse and irregularity,isointensity on T,-weighted images, isointensity or slight hypointensity on T2-weighted images, mild enhancement after Gadolinium,and all cases with asites, 1 case with swollen lymph nodes. Conclusion Recognition of the MRI characteristics of young women＇s ovarian thecoma is helpful to reduce the misdiagnosis.
