摘　　要：目的 探讨成人型卵巢颗粒细胞瘤的MRI表现及其临床特点,提高成人型卵巢颗粒细胞瘤的诊断能力。方法 回顾性分析19例经手术及病理证实的成人型卵巢颗粒细胞瘤的M RI表现及临床资料。结果 19例患者平均年龄为44.4±11.5岁,其中未绝经患者12人,平均年龄为37.6±7.7岁,绝经患者7人,平均年龄为57.3±2.4岁。18位患者有临床症状,以月经不规律及绝经后阴道出血为主。其中11位患者有激素检查结果,72.7%雌激素水平升高,卵泡刺激素水平均下降。MRI上18例为单侧肿块,1例为双侧,多表现为实性肿块内多发囊性灶及出血。T_(1)WI上以低信号为主,80%可见出血灶;T_(2)WI以高信号为主,85%可见“蜂窝征”及“海绵征”。结论 结合成人型卵巢颗粒细胞瘤特征MRI表现和临床特点,对于提高该病的术前诊断具有重要意义。Objective To investigate the MRI findings and clinical features of adult granulosa cell tumor of the ovary,and to improve the diagnostic a bility of adult granulosa cell tumor of the ovary.Methods MRI findings and clinical data of 19 cases of adult granulosa cell tumor confirmed by surgery and pathology were retrospectively analyzed.Results The average age of the 19 patients was 44.4±11.5 years,including 12 non-menopausal patients with an average age of 37.6±7.7 years and 7 menopausal patients with an average age of 57.3±2.4 years.18 patients had clinical symptoms,mainly including irregula r menstruation and postmenopa usal vaginal bleeding.11patients had hormone laboratory tests,which 72.7% estrogen levels were increased and follicle stimulating hormone levels were all decreased.MRI showed unilateral mass in 18 cases and bilateral masses in 1 case,most of which showed multiple cystic foci and bleeding signal.On T_(1)WI,most masses were hypointensity and bleeding signal was visible in 80% cases.On T_(2)WI,masses mainy showed hyperintensity and 85% cases showed "honeycomb sign" and "sponge sign".Conclusion The combination of MRI features and clinical features of adult granulosa cell tumor is of great significance for improving the preoperative diagnosis.
