胰腺导管内乳头状黏液性肿瘤的CT诊断

CT Diagnosis of Intraductal Papillary Mucinous Neoplasm of Pancreas

摘要: 目的:探讨胰腺导管内乳头状黏液性肿瘤(IPMN)的CT表现特征,以提高对该病的诊断能力。方法:回顾性分析经临床手术病理证实的16例IPMN病例CT图像,并作文献复习。结果:16例IPMN病例中,主胰管型3例,表现为主胰管扩张伴管壁结节样突起;分支胰管型7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或结节样突起;混合型6例,表现为主胰管扩张和囊性病变合并存在。结论:IPMN的CT表现有一定特征性,有助于对该病的正确诊断。

Abstract: Objective:To evaluate the CT findings and diagnostic value of intraductal papillary mucinous neoplasms(IPMN) of pancreas.Methods:16 cases of IPMN proved by pathohistological evidence and examined with plain and enhanced CT scans were retrospectively analyzed with literature reviewed.Results:Of 16 cases of IPMN,three cases of main-duct type pancreatic IPMN demonstrated dilation of pancreatic main duct with nodule on the wall of the duct.Five cases of branch-duct type pancreatic IPMN showed solitary or multiplecystic lesion with septa or nodule in the duct.6 cases of mixed type pancreatic IPMN displayed dilation of pancreatic main duct combined with cystic lesion.Conclusion:The CT findings of pancreatic IPMN are of certain characteristics,which is helpful to diagnose the disease correctly.
