摘　　要：目的分析卵巢颗粒细胞瘤(OGCT)临床及CT特征,以提高本病CT诊断水平。方法回顾性分析15例经手术与病理证实的OGCT临床资料和CT表现。14例行CT平扫加增强检查,1例行CT平扫。结果 15例肿瘤中13例为原发,2例为复发,临床表现不规则阴道流血2例,月经不规则1例,腹痛5例,腹胀3例,CA125升高2例,合并子宫内膜增生症2例,合并腹水6例。CT表现为盆腔内附件区囊实性肿块或边界清楚的软组织肿块,内见散在分布条状或小囊状低密度区,囊性区大小不一,CT增强扫描时肿瘤实质轻中度强化,低密度区无强化。结论 OGCT具有一定特征性的临床和CT表现。Objective To analyze the clinical and computed tomographic （CT） characteristics of ovarian granulosa cell tumor （OGCT） in order to improve the CT-based diagnosis of the disease. Methods The clinical data and CT findings of 15 patients with surgically and pathologically confirmed OGCTs were retrospectively analyzed. Fourteen patients underwent plain and contrast- enhanced CT, and t underwent a routine plain CT. Results Of the 15 patients, 13 had primary tumors and 2 had recurrent tumors. Two patients showed clinical manifestations of irregular vaginal bleeding, 1 had irregular menstruation, 5 had abdominal pain, 2 had abdominal distension, 2 had elevated CA125 levels, 2 had combined endometrial hyperplasia, and 6 had combined ascites. The CT scans revealed the presenc~ of pelvic adnexal solid/cystic or soft tissue masses with clear boundaries, in which scattered strips or low-density cystic areas of different sizes were observed. The contrast-enhanced CT scans showed mild to moderate enhancement in the tumor parenchyma, but no enhancement in the low-density area. Conclusion OGCT has certain clinical characteristic and CT manifestations.
