School ager with abdominal pain after a motor vehicle accident

CT of jejunal perforation
Axial CT with intravenous and oral contrast of the abdomen from the day of admission (above) shows a small amount of free fluid in the pelvis. There was no evidence of solid organ injury or free air. Repeat CT with intravenous and oral contrast from one day later due to increasing abdominal pain (below) shows a marked increase in the amount of free fluid present.

The diagnosis was jejunal perforation due to bowel trauma.
