【摘要】 目的探讨卵巢颗粒细胞瘤的CT表现特点,并与病理结果对照。资料与方法回顾性分析经手术病理证实的21例卵巢颗粒细胞瘤的CT资料。结果14例原发,其中2例为双侧病变;7例复发。所有肿瘤边界清楚,形态多规则。原发肿瘤呈多房蜂窝状囊实性肿物10个,实性肿物伴不同程度低密度区域5个,厚壁囊性肿物1个;肿瘤实性成分密度同肌肉相仿,增强后呈轻度强化;伴有子宫内膜增厚7例,腹腔积液7例,大网膜及腹膜增厚各2例。复发肿瘤表现与原发肿瘤相似。结论CT图像上能显示卵巢颗粒细胞瘤的特征,结合临床症状有助于正确诊断。更多还原

【Abstract】 Objective To study the CT features of ovarian granulosa cell tumor.Materials and Methods 21 cases of ovarian granulosa cell tumor proven pathologically were retrospectively analyzed.Results 14 cases were primary ovarian granulosa cell tumors,including two bilateral lesions.7 cases were recurrent lesions. The border of all mass was clear and regular. In primary cases,10 were multilocular solid mass with honeycomb change. 5 were solid mass with various area of low density inside. 1 was cystic mass with thick wall. The density of the solid part of the neoplasm was similar to the muscle and slightly enhanced. The primary neoplasms were associated with incrassated endometrium(n=7) and following ascites(n=6) and thickening omentum(n=2) or peritoneal(n=2).The features of recurrent neoplasm showed the same way as the primary one.Conclusion CT can demonstrate specific features of ovarian granulosa cell tumor,which may help the diagnosis combining with the clinical symptom.更多还原
