title: Intestinal polypoid arteriovenous malformation: unusual presentation in a child and review of the literature.
abstract: OBJECTIVE
  We report a jejuno-jejunal intussusception with a polypoid arteriovenous malformation as a lead point in a 12-year-old boy, presenting with lower abdominal pain and non-bloody non-projectile vomiting.
  
  
  METHODS
  A computed tomography scan of the abdomen and pelvis showed proximal jejuno-jejunal intussusception in the right upper quadrant. Exploratory laparotomy revealed a 5.5 × 2.5 × 2 cm polypoid mass within the wall of the jejunum. Consequently, jejunal segment resection was performed with end to end jejunostomy. Our case is distinctive because it involves a rare vascular lesion at an atypical site, the jejunum, in a child with an unusual presentation of intussusception treated surgically.
  
  
  CONCLUSIONS
  Many paediatric benign and surgical conditions present with similar clinical symptoms; the physician in the emergency department should try to narrow the differential diagnosis and recognize surgical emergencies to avoid any delay in intervention that could be life-threatening.
