摘　　要：目的:探讨十二指肠乳头旁憩室所致阻塞性黄疸的CT与MRI表现及其临床意义。方法:对15例经手术或ERCP证实的十二指肠乳头旁憩室所致阻塞性黄疸患者的CT与MRI进行回顾性分析。结果:十二指肠乳头旁憩室CT及MRI表现为乳头旁的含气和/或液囊性病灶,伴胆总管下端扩张,MRCP表现为十二指肠环内高信号病灶。15例中12例胆总管明显扩张,2例中度扩张,其中10例扩张胆总管伴壁增厚强化;8例伴胰管扩张;5例憩室壁较明显增厚强化。患者临床表现为黄疸伴不同程度的上腹部不适等症状。结论:CT及MRI能很好地显示十二指肠乳头旁憩室,后处理能比较直观地显示其全貌,同时能显示胰腺及胆管病变,有助于黄疸的诊断及鉴别诊断。Purpose：To evaluate the CT and MRI features and clinical significance of obstructive jaundice caused byjuxta-papillary duodenal diverticula Methods：The CT and MRI features of 15 cases surgery or ERCP proved juxta-papillary duodenal diverticula inducing obstructive jaundice were reviewed retrospectively.Results：Juxta-papillary duodenal diverticulum showed cystic lesions containing gas and/or liquid on CT and MRI images and high intensity lesion inside of duodenum C-loop on MRCP,accompanying the end of common bile duct dilation.In the 15 cases,severe common bile duct dilation were observed in 12 cases,moderate dilation in 2 cases; including common bile duct wall thickening and enhancement in 10 cases.Pancreatic duct dilation was shown in 8 cases.Diverticulum walls were thickening and enhanced obviously.All cases had jaundice and symptoms of epigastric discomfort.Conclusion：CT and MRI could clearly demonstrate juxtapapillary duodenal diverticulum,and pancreas and bile duct diseases simultaneously,which was helpful for diagnosis and differential diagnosis the cases of jaundice.
