case_images: 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).

case_images: 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).

case_images: Adjacent to this adhesion, the intussuscepted segment of the ileum was identified (Figure 3).
case_images: 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.

case_images: The intussusception was reduced, at which time a large polypoid lesion was identified (Figure 4).
case_images: 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.

case_images: There was a striking inflammatory infiltrate composed of abundant eosinophils as well as frequent plasma cells and occasional neutrophils (Figure 5).
