Occlusive intraluminal hematoma.

We report an unusual case of a 10-month-old girl who developed partial small-bowel obstruction caused by an intraluminal hematoma within the terminal ileum. Passage of bright red blood through her rectum prompted radiologic evaluation with computed tomography, barium enema, and ultrasound. These revealed an avascular right lower-quadrant mass within the lumen of the terminal ileum. An exploratory laparotomy was performed, and a large obstructing hematoma was removed.
