Pediatric Ileal Stenosis

  • Etiology: In utero vascular accident so it has no other associated congenital abnormalities
  • Imaging UpperGI: Focal dilation of the ileum
  • DDX:
  • Complications:
  • Treatment: Surgical
  • Clinical:
    — Less severe form of ileal atresia which often results in a delayed diagnosis
    — Much less common than ileal atresia

Radiology Cases of Ileal Stenosis

Upper GI and small bowel follow through of ileal stenosis
AXR AP (above) shows a distended abdomen with multiple dilated loops of bowel including an asymmetrically dilated loop of bowel in the right upper quadrant. Delayed images from an UGI small bowel follow through exam (below left) shows contrast entering this dilated loop which is in the distal ileum and eventually passing through this dilated loop and filling the appendix (below right).
