Contrast-enhanced CT scan showing branch duct IPMN. A cystic lesion can be seen with a markedly dilated side branch duct with wall thickening (arrow). (Adapted with permission from: Kim YH et al.)68 IPMN, intraductal papillary mucinous neoplasm.
MR cholangiopancreatogram showing a lesion suspicious for IPMN. Image shows a cystic, grape-like pancreatic lesion. It is not clear whether there is a communication of the mass and the pancreatic duct. Endoscopic retrograde cholangiopancreatography (ERCP) would be useful in this situation.

Cytology slide of IPMN aspirate from EUS-FNA. An intact cluster of moderately atypical epithelial cells with a single residual mucin vacuole. Even small numbers of such atypical cells warrant a suspicion of carcinoma. EUS, endoscopic ultrasound; FNA, fine needle aspiration; IPMN, intraductal papillary mucinous neoplasm.
