title: [Intraductal papillary mucinous neoplasm of the pancreas, IPMN].
abstract: With the development and increasing use of imaging techniques, intraductal papillary mucinous neoplasm (IPMN) is being detected with increasing frequency. Two forms of the disease are distinguished, the rare main duct form and the common accessory pancreatic duct form. The former often progresses to malignancy, the latter only seldom. The mixed form of IPMN exhibits features of both forms. In main duct IPMN, mucin production obstructs the pancreatic duct causing its dilatation and often symptoms typical of chronic pancreatitis. Main duct IPMN is always an indication for surgery, whereas monitoring is often sufficient for side duct IPMN.
