【摘要】：目的:探讨卵巢支持-间质细胞瘤(SLCT)的MRI表现,以提高对其诊断水平。资料和方法:回顾性分析5例经手术病理证实的SLCT MRI表现,并和临床、病理资料作对照分析。结果:本组5例,年龄26~64岁,3例有月经紊乱或闭经或不孕等去女性化表现,1例有多毛、痤疮、阴蒂肥大等男性化表现,1例表现为绝经后阴道流血症状,4例腹部可触及肿块。5例血睾酮升高。MR图像上,5例均为单侧,右侧2例,左侧3例,4例为实性,为圆形、卵圆形,T_1WI呈低信号,T_2WI呈稍高信号,DWI呈明显高信号,ADC图呈低信号,动态增强曲线呈速升-平台型,其中2例病灶内伴小囊状影,1例为多房囊实性,呈分叶状,囊性部分T_1WI呈低信号,T_2WI呈高信号,实性部分呈结节状,T_1WI呈低信号,T_2WI呈稍高信号,DWI呈高信号。病理上3例为高分化SLCT,1例为中等分化,1例为低分化,免疫组化表型,5例Inhibin-a、Vimentin均为阳性,5例EMA均为阴性。结论 :SLCT MR表现有一定特征,结合临床表现可提高术前诊断准确率,确诊依赖病理证实。
[Abstract]:Objective: to investigate the MRI findings of ovarian Sertoli stromal cell tumor (SLCT) in order to improve its diagnostic level. Materials and methods: SLCT MRI findings of 5 cases confirmed by operation and pathology were retrospectively analyzed and compared with clinical and pathological data. Results: in this group of 5 cases, 3 cases with menstrual disorder or amenorrhea or infertility, 1 case had hirsutism and acne, and 3 cases had menstrual disorder or amenorrhea or infertility. The masculine manifestation of clitoris hypertrophy in 1 case was postmenopausal vaginal bleeding. 5 cases with abdominal palpable mass. 5 cases with elevated serum testosterone. On MRI, 5 cases were unilateral, 2 cases were right side, 4 cases were solid on left side, 4 cases were round. The T _ 1WI of T _ 1WI was hypointense and the signal intensity was slightly high on T _ 2WI and DWI, and the dynamic enhancement curve was of the type of rapid ascending and plateau. In 2 cases, one case had multilocular cystic consolidation with small cystic shadow, and one case had lobular shape. The T_1WI in the cystic part showed hypointensity on T _ 2WI, and in the solid part in T _ 1WI, it was hypointensity on T _ 1WI, and on T _ 2WI, the signal intensity on T _ 2WI was a little higher than that on T _ 2WI. Histopathologically, 3 cases were well differentiated, 1 case was moderately differentiated, 1 case was poorly differentiated, and 5 cases were positive for Inhibin-a vimentin and 5 cases were negative for EMA. Conclusion the Mr findings of the 7% SLCT have some characteristics. Combining with the clinical manifestations, the accuracy of preoperative diagnosis can be improved, and the diagnosis depends on pathological confirmation.
