A CASE OF AUTOIMMUNE PANCREATITIS WITH THE OBSTRUCTION OF MAIN PANCREATIC DUCT COMBINED WITH THE RETROPERITONEAL FIBROSIS

Abstract

A 57-year-old man complaining of left leg edema was admitted to our hospital. Computed tomography and magnetic resonance imaging revealed a pancreatic tumor and retroperitoneal fibrosis. Endoscopic retrograde cholangiopancreatography showed an obstruction of the main pancreatic duct in the pancreas tail. He underwent a distal pancreatectomy with splenectomy, cohich revealed a histological diagnosis of autoimmune pancreatitis combined with retroperitoneal fibrosis. Corticosteroid therapy was started following operation. Corticosteroid therapy was effective for the autoimmune pancreatitis as well as for the retroperitoneal fibrosis. At present, twenty eight months after operation, the patient is on 10mg/day of predonisolone without disease recurrence.
