A case of annular pancreas in which the relationship between anuular pancreatic duct and pancreatic tissue was clarified by abdominal CT immediately performed after ERCP was reported. Sixty-six years old female was admitted to Akita Medical Center with a chief complaint of intermittent discomfort in the epigastrium for past two years. ERCP revealed annular pancreatic duct surrounding the second portion of the duodenum through cannulation from papilla of Vater. In addition, the relationship between annular pancreatic duct and pancreatic tissue with thickness of 1.2 cm was clarified by abdominal CT immediately performed after ERCP. No communication between annular pancreatic duct and dorsal pancreatic duct was confirmed through cannulations from both accesory papilla and papilla of Vater by the second ERCP. In addition to the case report, usefulness of abdominal CT immediately performed after ERCP for the diagnosis was discussed.
