Crohn's disease of the gallbladder.

In a 57-year-old woman, Crohn's disease involving the gallbladder and duodenum caused biliary tract obstruction and necessitated surgery. The patient's symptoms did not improve postoperatively until corticosteroids provided rapid resolution. Inflammatory bowel disease often involves the hepatobiliary tree, yet the gallbladder is rarely involved directly. This patient highlights a rare complication of Crohn's disease.
