We must keep the possibility of occult intestinal injury in mind for all patients presenting with blunt abdominal trauma, despite minimal physical signs.

Physical examination was normal apart from an area of mild tenderness to the right paraumbilical region, which corresponded to a 3×2-cm superficial abrasion caused by the handlebar.
