title: Segmental dilatation of the ileum.
abstract: Three new cases of congenital segmental dilatation of the ileum are presented and added to 12 cases of segmental dilatation found in the literature. The aspect of the condition which is of particular interest is the presence in 3 of the dilated segments of heteroplastic foregut derivatives of unusual varieties. The etiology of the condition is discussed; it does not appear to be a single distinct pathological entity.
