Recurrent pancreatitis in the setting of gallbladder agenesis, ansa pancreatica, Santorinicoele and eventual intraductal papillary mucinous neoplasia (IPMN)

Gallbladder agenesis is a rare condition. Patients with gallbladder agenesis can present with biliary type symptoms and rarely pancreatitis. We present the case of a 35-year-old gentleman who was admitted and treated for recurrent pancreatitis on a background of gallbladder agenesis, ansa pancreatica and Santorinicoele. He has had several admissions with pancreatitis and has had multiple imaging modalities during these admissions which we delineate. We discuss this rare anatomical variant and describe the course and management of his illness leading up to his eventual diagnosis of intraductal papillary neoplasia (IPMN).
