CT Diagnosis of Intraductal Papillary Mucinous Neoplasm of Pancreas

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.
