Summary:A 45-year-old woman visited our hospital due to upper left quadrant pain and melena. Colonoscopy revealed longitudinal ulcers in the transverse colon. The endoscopic findings and pathological examination of a biopsy specimen led to diagnosis of Crohn disease, and mesalazine was administered. Although the colorectal lesions showed improvement with mesalazine, a blood test revealed elevation of biliary enzymes. Endoscopic retrograde cholangiopancreatography showed diffuse narrowing of the main pancreatic duct and smooth stricture of the distal bile duct. Steroid therapy improved the pancreatic lesion, which was diagnosed as type 2 autoimmune pancreatitis.
