AXR of small bowel obstruction due to ileocolic intussusception
AXR supine (above left) shows multiple dilated loops of small bowel and AXR upright (above right) shows multiple air-fluid levels. There is no air in the colon. AP image from an air enema (below) shows a soft tissue mass outlined by air in the hepatic flexure which was then easily reduced to the ileocecal valve on the first attempt but could not be reduced further on subsequent attempts. In the operating room the terminal ileum and cecum were found to be necrotic and were resected.

The diagnosis was small bowel obstruction caused by ileocolic intussusception.
