目的：探讨卵巢卵泡膜细胞瘤的磁共振成像（MRI）的图像特征及其诊断与鉴别诊断的价值。方法回顾性分析30例经手术病理证实的卵巢卵泡膜细胞瘤的MRI特征，结合病理分析其表现特点。结果30例患者的病灶均为单发，其中圆形、卵圆形24例，分叶状6例，瘤体直径约3.6~21.4 cm，平均10.4 cm。实性肿瘤19例，囊实性9例，囊性2例；信号均匀者16例，信号不均者14例，增强扫描病灶轻度强化或不强化者22例，明显强化者8例。3例子宫内膜轻度增厚，1例子宫轻度增大。11例见瘤周积液，18例见子宫直肠窝少许积液。结论 MRI可有效显示卵泡膜细胞瘤病灶大小、形态、信号特征、强化情况以及有无腹水，并能较好地反映其病理生理特征，因此在卵巢卵泡膜细胞瘤的诊断及鉴别诊断中有着重要的价值。

Objective:To investigate the magnetic resonance imaging (MRI) appearance and dif erential diagnosis of ovarian thecoma. Methods:MRI pictures of 30 patients with histopathological y proved ovarian thecoma were observed retrospectively, and the MRI morphological characteristics were analyzed combining to pathological construction of them. Results:Al of the 30 tumors were single, in which 24 were orbicular or orbicular-ovate, 6 were lobulated in shape. The range of the diameters of the tumors were 3.6cm-21.4cm, mean diameter was 10.4cm. 19 cases were solid tumors, 9 were solid and cystic tumors and other 2 were cystic tumors. The MR signals of 16 cases were homogeneous, while other 14 cases were heterogeneous. Low or no enhancement could be observed in 22 cases, obvious enhancement could be observed in other 8 cases. There were 3 cases with incrassate endometria and 1 case with mild auxetic uterus. Fluid in the peripheric area of the lesions was noted in 11patients and intraperitoneal fluid in 18 patients. Conclusions:MRI scan can provide reliable information of the size, shape, signal characteristics, enhancement of ovarian thecoma and ascites in pelvic cavity. Meanwhile, it can present the pathological and pathophysiological changes of ovarian thecoma. Therefore MRI is valuable in diagnosis and dif erential diagnosis of ovarian thecoma.
