Posttraumatic intestinal stenosis: radiographic and sonographic appearance.

We report a case of posttraumatic intestinal stenosis (PIS), an uncommon sequela of blunt abdominal trauma, in which injury to the mesentery and bowel wall results in later focal ischemic stricture of that segment. We include CT images at the time of trauma, and barium meal and abdominal sonography obtained during the subsequent admission. Examination of the resected bowel loop showed transmural infarct and posttraumatic changes in the adjacent peritoneal fat. This is the first report which includes both imaging at the time of trauma and sonographic appearance of the narrowed bowel loop. Posttraumatic intestinal stenosis should be considered in the differential diagnosis of a narrowed bowel loop in a patient with a history of blunt abdominal trauma.
