儿童胰腺分裂的临床和磁共振特征分析

目的:分析单中心儿童胰腺分裂的影像,了解胰腺分裂的类型及分布特点,及其与儿童腹部疾病的关系.方法:回顾分析北京儿童医院2011年1月-2016年1月由于腹痛行上腹部核磁共振(MRI)及磁共振胰胆管成像(MRCP)检查的600例儿童的影像图像,最终影像诊断为胰腺分裂28例,其中女18例,男10例,按照胰腺分裂诊断标准进行影像分型.结果:MRI和MRCP综合诊断Ⅰ型为4例,Ⅱ型为22例,Ⅲ型为2例.28例胰腺分裂中10例合并特发性胰腺炎,18例合并胆总管囊肿.特发性胰腺炎中Ⅰ型2例,Ⅱ型7例,Ⅲ型1例,胆总管囊肿合并Ⅰ型2例,Ⅱ型15例,Ⅲ型1例.结论:MRI和MRCP相互结合可以很好诊断胰腺分裂畸形,同时儿童胰腺分裂多并发胰腺炎和胆总管囊肿.

Analysis of MRI and clinical characteristic of pancreas divisum in pediatric patients

Objective:To study the types and distribution characteristics of pancreas divisum (PD) and the relation-ship with abdominal disease in children by analyzing the magnetic resonance cholangiopancreatography (MRCP) and MRI features of PD in the single institution.Methods:The images of 600 children undergone MRI and MRCP because of adominal pain were retrospectively analyzed from January 2011 to January 2016 at Beijing Children Hospital 28 patients were diagnosed as PD and classified according to diagnostic criteria,including 18 females and 10 males.Results:4 children were diagnosed as Type Ⅰ PD,22 children were type Ⅱ and 2 children were type Ⅲ.10 children were associated with idiopathetic pancreatitis and 18 children with choledochal cyst.Of 10 children with idiopathtetic pancreatitis,there was type Ⅰ in 2 children,type Ⅱ in 7 children and type Ⅲ in one child.Of 18 children with choledochal cyst,there was type Ⅰ in 2 children,type Ⅱ in 15 children and type Ⅲ in one child.Conclusion:The combination of MRI and MRCP can clearly diagnose PD;PD in children were mostly associated with pancreatitis and choledochal cyst.
