Abstract

We report on a 10-year-old girl who presented with worsening pain and anorexia after blunt trauma to the abdomen. Contrast-enhanced CT of the abdomen was performed, and a counterclockwise rotation of the superior mesenteric vein around the superior mesenteric artery was seen. An upper gastrointestinal (UGI) series with small-bowel follow-through demonstrated a normally located duodenal–jejunal junction. This is the first case report of a counterclockwise barber-pole sign seen by CT with UGI that was negative for malrotation or volvulus.
