摘　　要：目的 分析新生儿卵巢囊性病变的CT及MRI表现.方法 回顾性分析经手术病理证实的7例新生儿卵巢囊性病变的资料,其中3例行CT检查,4例行MRI检查.由2名经验丰富的放射科医师共同分析病灶的影像学表现,并与病理学改变相对照.结果 7例患儿,可见8个卵巢囊性病灶,包括单纯性囊肿5例,其中合并扭转1例,滤泡囊肿合并出血1例,卵巢坏死1例,额外卵巢合并出血1例.未合并扭转的单纯性囊肿在CT或MRI表现为单纯型囊肿,其他病变表现为复杂型囊肿,出现碎屑-液平面、液-液平面、强化结节等.结论 新生儿卵巢囊性病变多为肿瘤样病变,CT和MRI特征可有助于区分单纯性囊肿与其他亟须处理的囊性病变,较好反映病变的病理学状态.Objective To analyze CT and MRI findings of ovarian cystic masses in neonates.Methods The date of 7 patients with ovarian cystic masses in neonates proved by operative pathology were analyzed retrospectively.Of 7 neonates,3 neonates were performed CT examinations,while 4 neonates were performed MRI examinations.Two experienced radiologists analyzed the radiologie features of the ovarian masses based on CT or MRI together.Additionally,the radiologic-pathologic correlation of masses was conducted too.Results Eight ovarian cystic masses were found in 7 neonates,including 5 cases of simple cysts,among which 1 case was found to complicated by torsion,1 case of hemorrhagic follicular cyst,1 case of ovarian necrosis and 1 case of supernumerary ovary complicated with hemorrhage.On CT or MRI,ovarian simple cysts(withour torsion)exhibited simple cystic appearances,while other lesions exhibited complex cystic appearances,including debris-fluid level,fluid-fluid level and enhanced nodules. Conclusion Tumor-like lesions contribute mainly to ovarian cystic masses of neonates.CT and MRI examinations are helpful to distinguish ovarian complex cysts of emergency from simple cysts, reffecting pathologic changes of ovarian muasses.
