title: A communicating intestinal duplication in a Sprague-Dawley rat.
abstract: Duplications of the gastrointestinal tract are exceedingly rare in laboratory animals. We report a case of a communicating intestinal duplication in a 17-wk-old Sprague-Dawley (SD) rat. The duplication was present in the mesenteric border of the ileum, and both proximal and distal ends were communicated with the lumen of ileum. Histologically, the duplicated portion had a thick muscle wall and a mucosa similar to that of the small intestine. This is the first reported case of intestinal duplication in an SD rat.
