Objective To study the multi-slice CT (MSCT) and magnetic resonance cholangio-pancreatography (MRCP) features of intraductal papillary mucinous tumor (IPMT) of the pancreas. Methods The clinical information, laboratory values, imaging features and pathological findings of 8 cases were reviewed. Results There were 6 males and 2 females with average 71.3 years old in this series. These lesions involved pancreatic branch ducts or main duct. Among them, 2 cases were involved in the pancreatic uncinate process, 1 case in the pancreatic head, 1 in the pancreatic body, 2 in the pancreatic tail and 2 cases involved multiple pancreatic duct. The common complaint was chronic upper abdominal pain. The imaging features included cystic lesion and it’s association with the dilated pancreatic main duct, and bulging of the duodenal papilla. Mucin plug, septa or mural nodule were found in these cystic lesions. 5 cases were confirmed with endoscopic retrograde cholangio-pancreatography (ERCP). 3 cases had undergone surgery. Pathological findings of the 3 cases were adenoma, adenocarcinoma and borderline tumor, respectively. Conclusion The MSCT and MRCP features of IPMT are somewhat characteristic, and the correct diagnosis can be made with the combination of clinical features. Diameter of branch duct ?3 cm with multiple or large mural nodules, or severe dilated main duct indicates the probability of malignant IPMT.
