[Double ileo-ileal and ileo-cecocolic intussusception due to submucous lipoma: case report].

Intestinal intussusception is a rare pathology in adults and counts for approximately 5-16% of all invaginations, according to literature. We report the case of a 54 years-old male affected by a double ileo-ileal and ileocecocolic invagination secondary to a submucosal intestinal lipoma. Because of a bowel obstruction symptomathology, the diagnosis was based on abdomen X-rays, abdominal ultrasound and multislice CT scan that showed a probable pre-operative diagnosis of intestinal intussusception. The diagnosis of double invagination was confirmed intraoperatively and was therefore performed a right colectomy extended to a long tract of ileum. Opening the specimen demonstrated the evidence of a submucosal lipoma on the head of the intussusceptum. After the description of this case, we proceed with review of the literature of adult intestinal invagination.
