A case of IPMN in which the pancreatic resection line was evaluated using simultaneous construction images of the main pancreatic duct and arteries from MD-CT

Abstract

We report a case of IPMN in which the pancreatic resection line was evaluated using simultaneous construction images of the main pancreatic duct and arteries from MD-CT. A 61-year-old male was found to have a cyst in the pancreatic body two years before. EUS confirmed a mural nodule 5.5mm in diameter in the main pancreatic duct of the pancreatic body. 3D construction images of the pancreatic arteries and the main pancreatic duct by MD-CT revealed dilatation of the main pancreatic duct where the gastroduodenal artery branches from the great pancreatic artery. After cutting the pancreatic tail at the position of the great pancreatic artery, the pancreatic parenchyma was separated cranially and resected at the portion where the gastroduodenal artery is present. Middle pancreatectomy was done. Histopathological examination revealed intraductal papillary mucinous adenoma. The tumor existed in the main pancreatic duct and had spread into the epithelium of the branches.
