Delayed intestinal stenosis after blunt abdominal trauma: report of a case.

Major intestinal injury may be present with very subtle clinical and/or imaging findings. Sometimes, delayed intestinal stenosis may occur even several months after the blunt abdominal trauma. We present a 12-year-old boy with delayed jejunal stenosis following blunt abdominal injury in a car collision. Computed tomography (CT) scan showed streaky infiltrates in the mesentery and fluid densities in the bilateral anterior pararenal spaces as well as enhancement of bowel wall on the 2nd day after trauma. A "bird-beak" sign at the proximal jejunum with diffuse mucosal swelling of jejunal loops were seen on barium follow-up study on the 7th day. Complete obstruction at the duodenojejunal junction was identified by the follow-up barium examination on the 29th day.
