title: Polypoid arteriovenous malformation presenting with jejunojejunal intussusceptions in an adult.
abstract: Jejunal polypoid arteriovenous malformations (AVMs) and jejunojejunal intussusceptions are both rare. Here, we present the case of a 61-year-old woman who suffered intermittent episodes of abdominal pain over the course of 13 years. A computed tomography scan of her abdomen and pelvis revealed a distal jejunojejunal intussusception. A suspected low density mass was observed at the tip of the intussusception. Treatment comprised laparoscopic small bowel resection with end-to-end jejunostomy. The final diagnosis was a polypoid AVM measuring 5×3.5×3 cm. We suggest that polypoid AVM should be considered as a differential diagnosis in patients presenting with small intestinal neoplasms.
