摘　　要：目的:探讨胰腺导管内乳头状黏液性肿瘤(intraductal papillary mucinous neoplasm,IPMN)的CT和磁共振成像(mag-netic resonance imaging,MRI)影像学表现。方法:回顾性分析经手术病理证实的18例胰腺导管内乳头状黏液性肿瘤的影像资料与病理诊断。结果:主胰管型IPMN 3例,表现为主胰管扩张;分支胰管型IPMN 5例,表现为分叶状单发囊性病变或葡萄串样多发囊性病变伴腔内分隔;混合型IPMN 10例,表现为囊性病变伴主胰管扩张。结论:CT和MRI对胰腺IPMN的诊断具有重要价值。Objective：To investigate the manifestations of CT and magnetic resonance imaging （MRI） in intraductal papillary mucinous neoplasm （IPMN） of the pancreas. Methods：The CT and MRI findings of 18 patients with pathologically confirmed IPMN of the pancreas were retrospectively analyzed. Results： Three cases of main-duct type pancreatic IPMN showed dilation of pancreatic main ducts. Five cases of branch-duct type pancreatic IPMN demonstrated solitary or multiple cystic lesions with septa. Ten cases of mixed-type pancreatic IPMN displayed dilation of pancreatic main ducts with cystic lesions. Conclusions： CT and MRI are help- ful to the diagnosis of IPMN of the pancreas.
