A Rare Case of an Intraductal Papillary Mucinous Neoplasm of Pancreas Fistulizing Into Duodenum With Adult Polycystic Kidney Disease

Abstract

Intraductal papillary mucinous neoplasm (IPMN) accounts for 20-50% of all cystic neoplasms of the pancreas. Rarely, IPMN, whether benign or malignant, can fistulize into adjacent organs like duodenum, stomach or common bile duct. IPMN can be associated with other diseases like Peutz-Jeghers syndrome and familial adenomatous polyposis. Association with adult polycystic kidney disease (ADPKD) is extremely rare. We report a case of a 60-year-old male with a large IPMN in the head of the pancreas diagnosed by magnetic resonance imaging, endoscopic ultrasound and cyst fluid analysis. It was complicated by fistula formation into the second part of the duodenum. Patient was simultaneously having adult polycystic kidney disease. There is only one case report of uncomplicated IPMN with ADPKD in the literature so far. And even rarer, there is no any case report of fistulizing IPMN with ADPKD reported so far, to the best of our knowledge.
