胰腺导管内乳头状黏液性肿瘤的MSCT和MRCP诊断

Multi-slice CT and MR cholangio-pancreatographic diagnosis of intraductal papillary mucinous neoplasm of the pancreas

目的探讨胰腺导管内乳头状黏液性肿瘤(IPMN)的MSCT和MRCP影像学表现。方法对26例经内镜或手术病理证实的IPMT患者的CT和MRCP表现进行回顾性分析。结果分支胰管型IPMN12例,表现为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;主胰管型IPMN 5例,表现为主胰管扩张伴管壁结节样突起;混合型IPMN9例,表现为主胰管扩张和囊性病变合并存在。9例手术病理结果为腺瘤1例,交界性肿瘤2例,腺癌6例。结论 MSCT和MRCP对发现和诊断胰腺IPMN具有较高价值。

Objective To evaluate the multi-slice CT （MSCT） and magnetie resonance cholangio-pancreatography （MRCP） features of intraductal papillary mucinous neoplasm （IPMN） of the pancreas. Methods The CT and MR CP of 26 cases of IPMN including adenocarcinoma （6 cases）, borderline malignancy （2）, and adenoma （1） were reviewed. Results CT and MRI of IPMN in the pancreatic ductal branches （12 cases） showed solitalT or multiple cystic lesions with sepia or nodules in the ducts. In the 5 patients with main pancreatic duct IPMN, there was dilation of the main pancreatic duct with mural nodule. In 9 patienls with mixed type pancreatic IPMN, dilation of the main pancreatic duct and cystic lesions were noted. Conclusion MSCT and MRCP are useful in the diagnosis of pancreatic IPMN.
