Intestinal intussusception is the invagination of an intestinal segment into another. Childhood intussusception is usually idiopathic, whereas adult intussusception is usually due to a definable intraluminal lesion or to a systemic disease. Although the aetiology of idiopathic forms often remains unclear, there is appreciable evidence to support an indirect role played by certain infectious agents. In this report we present a case of childhood intussusception probably due to adenovirus infection.
