Computed tomography of the abdomen and pelvis with intravenous contrast revealed ileoileal intussusception with local inflammatory changes and proximal early small bowel obstruction (Figures 1 and 2).

Computed tomography of the abdomen and pelvis with intravenous contrast revealed ileoileal intussusception with local inflammatory changes and proximal early small bowel obstruction (Figures 1 and 2).

Adjacent to this adhesion, the intussuscepted segment of the ileum was identified (Figure 3).
Postoperative specimen. After segmental small bowel resection was performed, the intussuscepted segment was reduced on the back table. The polyp measured 7.5 x 4.5 x 3.2 cm grossly.

The intussusception was reduced, at which time a large polypoid lesion was identified (Figure 4).
Photomicrograph of small bowel polyp. H&E staining demonstrates myxedematous stroma with prominent vessels and a striking inflammatory infiltrate composed of abundant eosinophils. Inset shows magnification.
