title: Involvement of Meckel diverticulum in Crohn disease associated with pancreatic heterotopia.
abstract: Although the association of Crohn disease and Meckel diverticulum has been widely reported, the direct involvement of a Meckel diverticulum by Crohn disease is less common and is usually the result of contiguous spread. The presence of heterotopic tissues in an affected diverticulum is rare and most often consists of gastric mucosa. We report herein the presence of Crohn disease within a Meckel diverticulum, with a normal small bowel immediately adjacent to the diverticulum, associated with pancreatic heterotopia.
