Intussusception of the bowel in adults: A review

Figure 1 Abdominal computed tomography in adult intussusception. A: The characteristic “target”-shaped soft-tissue mass with a layering effect of a 29-year old male patient with a diffuse, small B-cell (Burkitt-like) non Hodgkin lymphoma of the ileum who developed an ileo-colic intussusception; B: A “sausage”-shaped soft tissue mass in the ascending colon of the same patient.

Figure 2 Colonoscopy. Revealing the presence of the inverted terminal ileum (intussusceptum) in the ascending colon (intussuscipiens) in a patient with an ileo-cecal intussusception due to an ileal lipoma.

Figure 3 Intraoperative findings. A: Thickened, congested and inflamed terminal ileum with proximal small bowel obstruction in a 75-year old woman with ileo-colonic intussusception; B: The surgical specimen after the en bloc resection of the terminal ileum and the ascending colon in the same patient; C: The cause of the intussusception was a lipoma of the ileo-cecal valve (arrow).
