A contrasted abdominal CT showed ileocecal intussusception (Fig. 1, Fig. 2).
Sectioning of the right hemicolectomy specimen revealed telescoping of the distal ileum into the cecum through the ileocecal valve. The terminal ileum wall was thickened and fibrotic with whitish solid nodules. Multiple small polyps were seen in the cecum and part of the ascending colon mucosa.
