Background:
Pancreatic intraductal papillary mucinous neoplasms (IPMNs) are a subset of ductal cell tumors with potential for malignancy. Because it is difficult to predict whether and when they will become malignant, management and resection are widely debated.
Case 1:
A 70-year-old male with a 1-year history of epigastric pain was found to have pancreas divisum with a dominant 2.4 cm multicystic uncinate process lesion communicating with the main pancreatic duct and associated uncinate duct dilation.
Case 2:
An 83-year-old male with pancreas divisum had a 7.3 cm uncinate cystic lesion with mural nodularity that had increased in size from 2.1 cm in 2008.
Conclusion:
Management of patients with IPMNs can be challenging and may require resection to prevent malignant transformation.
