摘要
目的:探讨卵巢纤维卵泡膜细胞瘤的MRI表现特点。方法:回顾性分析经手术病理证实的13例卵巢纤维卵泡膜细胞瘤的MRI资料。结果:所有卵巢纤维卵泡膜细胞瘤MRI表现为边界清晰肿块,均可见包膜,其内可有坏死、囊变或出血。与子宫肌层信号比较,肿块T1WI呈等、低信号,T2WI呈混杂信号,增强扫描呈不均匀强化,尤其当肿瘤较大时更常见。卵巢纤维卵泡膜细胞瘤的平均强化程度显著低于子宫肌层(P<0.05)。结论:MRI有助于卵巢纤维卵泡膜细胞瘤的术前诊断。
Objective：To investigate MRI imaging characteristics of ovarian fibrothecoma. Methods：A retrospective a nalysis of MRI images was performed in 13 patients with pathologically proven ovarian fibrothecoma. Results： All ovarian fi brothecomas were well defined with capsule. Degeneration, cystic changes or hemorrhage could be seen in the tumors. Tt^e tumors exhibited isointensity and hypointensity on T, WI, heterogeneous signal on T2 Wl and heterogeneous enhancement which were more likely noted in the bigger one. The mean enhancement of fibrothecomas was significantly less intense than that of myometrium （P〈0.05）. Conclusion： MRI plays an important role in the diagnosis of ovarian fibrothecoma.
