title: Segmental mega-ileum presenting as anaemia.
abstract: Three cases are described of an unusual malformation of the ileum at the site of the vitelline duct, which presented with chronic anaemia. In each case localized mega-ileum was associated with a simple, non-specific ulcer leading to chronic blood loss. Two cases were at the site of and associated with a Meckel's diverticulum, while the third case was at the same level and associated with a vascular abnormality probably of vitelline artery origin. Ths syndrome of adult segmental ileal dilatation associated with non-specific ulcer and chronic anaemia does not appear to have been described previously.
