摘　　要：目的 探讨磁共振(MRI)在诊断先天性宫颈闭锁及其分型中的价值。方法 回顾性分析10例经手术证实为先天性宫颈闭锁患者的MRI特征,并对其进行分型。结果 10例患者中,Ⅰ型3例,Ⅱ型4例,Ⅲ型1例,Ⅳ型2例。10例患者均合并Ⅱ型阴道闭锁,2例为单角子宫。Ⅰ型子宫呈“平底锅”样改变,子宫体部大小正常,子宫体腔无明显积血,子宫峡部末端呈盲端,子宫峡部明显积血扩张。Ⅱ型子宫体部末端呈盲端,子宫体腔积血,子宫峡部、子宫颈管缺如。Ⅲ型子宫峡部及子宫颈管闭锁呈长条形实性软组织,子宫体部发育不良。Ⅳ型子宫体部下段与呈盲端的宫颈管相连,子宫体腔及宫颈管积血扩张,子宫体腔扩张程度大于宫颈管。8例患者均合并不同程度的输卵管积血、卵巢巧克力囊肿及盆腔粘连。结论 MRI不仅能明确诊断先天性宫颈闭锁并对其分型,还能同时了解盆腔内异症情况,为临床诊疗提供有价值的信息。Objective To investigate the value of magnetic resonance imaging(MRI)in the diagnosis and classification of congenital cervical atresia.Methods The MRI features of 10 cases with congenital cervical atresia confirmed by surgery were retrospectively analyzed and classified.Results Among the 10 patients,there were 3 cases ofⅠtype,4 cases ofⅡtype,1 case ofⅢtype and 2 cases ofⅣtype.All the 10 patients were complicated withⅡtype vaginal atresia,and 2 patients with unicornous uterus.TheⅠtype uterus showed a"pan"shape,the size of the uterus body was normal,and there was no obvious hemocele in the uterine body cavity.The end of the isthmus of the uterus was blind,and the isthmus of the uterus was obviously hematoceles and dilatation.Ⅱtype uterus showed the end of uterine body was blind,there was hemocele in the uterine body cavity,and uterine isthmus and cervical canal are absent.Ⅲtype of uterine isthmus and cervical canal atresia presented long solid soft tissue,uterine body dysplasia.The lower part of theⅣtype uterine body is connected with the blind cervical canal.The uterine body cavity and the cervical canal dilate with accumulated blood.The dilation degree of uterine body cavity is greater than that of the cervical canal.Eight patients were complicated with different degrees of tubal hemorrhage,ovarian chocolate cyst and pelvic adhesion.Conclusion MRI can not only diagnose and classify congenital cervical atresia,but also explore the characteristics of pelvic endometriosis.It can provide valuable information for clinical diagnosis and treatment.
