Intraductal papillary mucinous neoplasm complicated by a gastropancreatic fistula

Abstract

One of the rare complications of low-grade pancreatic neoplasms is fistulization into nearby structures. This often does not present clinically, but is incidentally identified in patients who have been imaged serially to monitor the progression of the disease. In this report, we present an uncommon complication of an intraductal papillary mucinous neoplasm, which developed a spontaneous gastropancreatic fistula in a patient who was conservatively managed. The clinical course, imaging features, and management of this case are discussed. Keywords: Intraductal papillary mucinous neoplasm, Gastropancreatic fistula
