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。
Objective: To investigate the CT features of intraductal papillary mucinous neoplasm (IPMN) in order to improve the diagnostic ability of this disease. Methods: The CT images of 16 cases of IPMN confirmed by clinical pathology were retrospectively analyzed and reviewed. Results: In 16 cases of IPMN, the main pancreatic duct was found in 3 cases, which showed the dilatation of the main pancreatic duct with nodular nodules. In 7 IPMN cases, there were 7 cases of branch pancreatic duct, which showed lobulated single cystic lesion or grape cluster Multiple cystic lesions with intracavitary separation or nodular-like processes; mixed type in 6 cases, the performance of the main pancreatic duct dilatation and cystic lesions merged. Conclusion: The CT findings of IPMN have certain characteristics, which are helpful for the correct diagnosis of the disease.
