摘　　要：目的分析卵巢颗粒细胞瘤（OGCT）的CT表现,提高诊断及鉴别诊断能力。方法回顾性分析8例经手术病理证实为OGCT的患者的临床特点及CT资料。结果 8例肿瘤均为原发病灶且均单发,左侧卵巢3例,右侧卵巢5例,均呈椭圆形或类圆形。CT平扫：肿块边缘光滑,与周围组织分界清楚,6例肿块表现为多发囊实性,2例肿块为实性。增强扫描8例均为不均匀强化,5例中度强化（CT值升高21.3~39.0 HU）,2例明显强化（CT值平均升高56.1 HU）,1例轻度强化（CT值升高11.8 HU）。其中5例伴有子宫体积增大、子宫内膜增厚,3例伴有腹水,其中1例为大量腹水。结论OGCT的CT表现有一定特征性,结合临床症状和CT表现有助于对本病的诊断及鉴别诊断。Objective To evaluate the clinical characteristics and CT manifestations of ovarian granulosa cell tumor（ OGCT）and improve the diagnostic and differential diagnostic ability. Methods The clinical characteristics and CT manifestations of 8patients with OGCT confirmed by histopathology were retrospectively analyzed. Results A total of 8 cases were primary OGCT and all cases were solitary lesions,3 cases in left adnexa and 5 cases in right. All cases were round or ovoid mass. CT manifestations： The margin of all the tumors was clear. 6 cases were cystic- solid lesions,and 2 cases were solid lesions. All cases were enhanced heterogeneous,5 cases moderately,2 cases significantly and 1 case slightly. The tumors were accompanied by enlarged uterus and incrassated endometrium（ n = 5）,ascites（ n = 3）,1 with massive ascites. Conclusion OGCT has some specific CT manifestations. CT manifestations combined with clinical characteristics are helpful in the diagnosis and differential diagnosis of OGCT.
