title: Intussusception and total body opacification.
abstract: Because of atypical clinical presentations, two children with intussusception had intravenous urography as their initial examination of following plan films. In both patients the intussusception was outlined by an opaque rim due to the total body opacification effect on the bowel wall. One patient had a target-like blush on following films which strongly suggested the correct diagnosis. The authors do not advocate intravenous urography to diagnosis intussusception, but if this study is performed because of atypical clinical findings, the radiographic sign should be recognized and lead to a barium enema.
