title: Colonic arteriovenous malformation in a child misinterpreted as an idiopathic colonic varicosis on angiography: remarks on current classification of childhood intestinal vascular malformations.
abstract: A case of lower gastrointestinal hemorrhage in a child caused by an arteriovenous malformation (AVM) of the colon is presented. On diagnostic angiography, the lesion was misinterpretated as an idiopathic colonic varicosis because none of the characteristic features of an AVM were present. The role of angiography and shortcomings in nomenclature and classification of intestinal vascular anomalies in childhood are discussed.
