| 摘 要： | 目的分析卵巢卵泡膜细胞瘤的MRI特征并与病理结果进行对照,旨在提高对卵巢卵泡膜细胞瘤的诊断水平。方法回顾性分析13例卵泡膜细胞瘤的临床、影像、病理资料。结果 13例共16个病灶(单发10例,双侧3例)。肿瘤为圆形或卵圆形或分叶状的实性肿块,T_2WI呈低信号为主,代表富含成纤维母细胞成分的区域,其内不同程度长T_2水肿、囊变区。增强扫描肿瘤呈轻~中度渐进性强化,肿瘤由卵巢动脉供血。结论卵巢卵泡膜细胞瘤MRI表现能反应肿瘤起源及其病理特征,对本病诊断及鉴别诊断有重要价值。

| Abstract: | Objective To correlate the MRI findings of ovarian thecoma with pathology.Methods The clinical features and MRI appearance of 13 patients with 16 ovarian thecomas were reviewed and correlated with pathology.Results Most of the tumors were round or oval,less often lobulated.T2 hypointense areas corresponded to abundant fibroblasts in the tumors with scattered T2 hyperintense areas representing edema or cystic degeneration.The tumors were supplied by ovarian arteries with slight or moderate progressive contrast enhancement.Conclusion The MRI appearance aids in the diagnosis of ovarian thecoma. |
