Crohn's disease in a Meckel's diverticulum: report of a case.

Meckel's diverticulum has previously been reported to be present in patients with Crohn's disease. However, the finding is typically an incidental one, and involvement of the diverticulum in the disease process is uncommon. We report a case of an adolescent with known Crohn's disease who presented with symptoms thought to be due to terminal ileitis. At the time of laparoscopy the inflammation was found to be due to involvement of the Meckel's diverticulum with Crohn's disease.
