目的：分析卵巢卵泡膜瘤-纤维瘤的MRI表现，探讨MRI的诊断价值。方法：42例经手术病理证实的卵泡膜瘤-纤维瘤患者，回顾性分析其MRI表现。结果：本组病例中包括卵泡膜细胞瘤2例，纤维瘤21例，卵泡膜纤维瘤19例，肿瘤边界清楚，多呈实性。纤维瘤T2WI呈低信号15例，低信号为主混杂信号6例；卵泡膜细胞瘤T2WI均呈稍高信号为主混杂信号；卵泡膜纤维瘤T2WI呈低信号2例，等信号或稍高信号为主的混杂信号17例；所有肿瘤T1WI均呈等信号或低信号；增强扫描后38例为轻度延迟强化，3例无明显强化，1例显著持续强化。结论：卵巢卵泡膜瘤-纤维瘤的MRI表现具有一定特征性，对于临床定性、定位诊断均有较高参考价值。

ObjectiveTo analyze the MR appearance of ovarian thecoma -fibromas and investigate the diagnostic value of MRI.Methods: The MR images of 42 cases of ovarian thecoma -fibromas confirmed by histopathology were retrospectively analyzed.Re-sults:There were 2 cases thecoma , 21 cases fibroma and 19 cases fibrothecoma of 42 patients.Tumors were solid with well -defined margins.On T2WI, fibromas showed hypo -intensity in 15 cases and mixed intensity in 6 cases, thecoma showed slight hyper -inten-sity, fibrothecoma showed hypo -intensity in 2 cases and mixed intensity in 17 cases.All tumors showed iso -intensity or hypo -in-tensity on T1WI.Slight enhancement was shown in 38 cases, no enhancement in 3 cases, marked enhancement in 1 case after injection of contrast medium.Conclusion:MRI findings of ovarian thecoma -fibromas are characteristic and have a higher reference value in clinical qualitation and positioning diagnosis.
