A case is described of a 19-month-old boy who presented with melaena. Intestinal duplication was diagnosed by 99Tcm-pertechnetate scanning and was confirmed at operation 2 years later, when the child was admitted with intestinal perforation. The technique is a reliable, non-invasive method for diagnosing ectopic gastric mucosa and is recommended in all cases of unexplained rectal bleeding in children.
