From: The prevalence of circumportal pancreas as shown by multidetector-row computed tomography
An 80-year-old male patient with intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head and circumportal pancreas. a Preoperative magnetic resonance cholangiopancreatography (MRCP) shows multilocular cystic mass with dilatation of the downstream main pancreatic duct (MPD) in the pancreatic head, consistent with IPMN (large arrow). b The portal venous phase of preoperative MDCT shows circumportal pancreas. IPMN component extends to an aberrant pancreatic tissue (large arrow). c Sagittal reformatted image obtained from the portal venous phase shows an aberrant pancreatic tissue (arrow) above the splenoportal confluence as well as IPMN. d Follow-up MDCT 6 months after the segmental duodenectomy for IPMN demonstrates a 2-cm multilocular cystic mass at the dorsal aspect of the portal vein (arrow). e Source image of coronal MRCP shows the communication between the main pancreatic duct and the cystic lesion (arrow). The cystic lesion turned out to be a retention cyst with granulation tissues
