ABSTRACT

A 78-year-old woman visiting our hospital with the chief complaint of abdominal pain was diagnosed with ischemic colitis. CT pointed out pancreatic enlargement, so detailed pancreatic examination was conducted in parallel with treatment. In enhanced CT and MRI, the main pancreatic duct significantly extended over the entire length, and mural nodules scattered in the main pancreatic duct were observed. It was diagnosed with main duct intraductal papillary mucinous neoplasm (IPMN), which is likely to be intraductal papillary mucinous carcinoma(IPMC), and total pancreatectomy was performed. Pathological findings showed diffuse dilation of the main pancreatic duct, non-invasive IPMC progressed over approximately the entire length of the main pancreatic duct, mucinous carcinoma-tubular adenocarcinoma was widely infiltrated in pancreatic tissues around mural nodules. The cancer remained in the pancreas and was eventually diagnosed with IPMC, invasive, pT2, pN0, and pStage ⅠB. This case was an IPMN with high-risk stigmata, and it was an adaptive case of total pancreatectomy because mural nodules extended to the entire pancreas. In recent years, total pancreatectomy has come to be expected good results by the progress of diabetes treatment and the development of pancreatic enzyme agents, it is necessary to carefully judge each case for adaptation.

ABSTRACT

A 67-year-old man visiting our hospital with the chief complaint of sudden upper abdominal pain was diagnosed with acute pancreatitis. Based on computed tomography findings, intraductal papillary mucinous neoplasm(IPMN)was suspected as the cause of the pancreatitis and detailed examination was conducted following its alleviation. Endoscopic retrograde and magnetic resonance cholangiopancreatography showed marked dilation of the main pancreatic duct, with a mural nodule inside the main pancreatic duct at the pancreatic head. Main duct IPMN was diagnosed and pancreaticoduodenectomy was performed 3 months after the onset of acute pancreatitis. The histopathological findings showed a tumor proliferating in a mold pattern in the lumen of the dilated main pancreatic duct, resulting in a diagnosis of intraductal papillary mucinous carcinoma(IPMC). The presence of IPMN should be considered as a cause of acute pancreatitis; if findings suggestive of IPMN are found on imaging, detailed examinations and treatment are needed in consideration of the potential for malignancy following alleviation of pancreatitis.
