摘要
目的:探讨卵巢卵泡膜纤维瘤的MRI诊断。方法:收集手术病理证实的21例卵巢卵泡膜纤维瘤MRI检查资料,分析其临床资料和MRI表现。结果:MRI表现为平扫MRI示附件区T_1WI等信号或略低信号,T_2WI为高低混合信号,边界清晰,7例有水肿或坏死,在T_2WI上信号强度升高,增强后肿块周边及内部软组织密度稍强化,水肿及坏死组织未见强化。结论:MRI对卵巢卵泡膜纤维瘤具有特殊的诊断价值。
Purpose： The purpose of the study was to explore the value of MRI in diagnosis of ovarian fibrothecoma. Methods： Twenty-one patients with ovarian fibrothecomas confirmed by operation and pathological results underwent MRI scan preoperatively, whose clinical data and MRI features were analyzed. Results： Non-enhanced MRI scan revealed mass of iso-intensity or slight hypo-intensity on TI- weighted images and mixed hyper- and hypo-intensity on T2-weighted images in adnexal region, the borders of which were clear, edema or necrosis could be seen in 7 patients. The solid portion of the tumor was slightly enhanced on post-contrasted MR images. Conclusion： MR imaging is highly accurate in diagnosing the ovarian fibrothecomas.
