Teenager with paraplegia who uses an appendicovesicostomy for self-catheterization who now has abdominal distension and no stool for one week

Enema of cecal volvulus — AXR AP taken immediately after an enema shows multiple dilated loops of air-filled small bowel with no reflux of contrast into the terminal ileum. The ascending colon ends in a beak which points to a dilated air-filled cecum in the right lower quadrant.

The diagnosis was distal small bowel obstruction caused by cecal volvulus.
