Figure 34. Intraductal papillary mucinous tumor in patient presenting with recurrent pancreatitis. (A) MRCP after secretin administration demonstrates a pancreas divisum with minute communication and an irregular fluid-filled lesion (arrow) communicating with the ventral portion of the duct. (B, C) Corresponding ERCP images obtained after selective retrograde iodine contrast material injection fails to demonstrate the cystic tumor. In C, selective catheterization of the ventral portion of the pancreatic duct is shown.
