Enteric Duplication Cyst of the Pancreas Associated with Chronic Pancreatitis and Pancreatic Cancer

Pancreas-associated enteric duplication cysts are rare developmental anomalies that communicate with the main pancreatic duct and may be associated with recurrent acute and chronic abdominal pain in children. In adults, these lesions may masquerade as pancreatic pseudocysts or pancreatic cystic neoplasms. An adult patient with a pancreas-associated enteric duplication is described which represents the first reported instance of association with both chronic calcific pancreatitis and pancreatic cancer. The clinical spectrum of pancreas-associated enteric duplication cyst, including diagnostic and therapeutic options, is reviewed.
