Seatbelt sign (abdomen)

Dr Henry Knipe et al.

The seatbelt sign is both a clinical and radiological sign. It is simply the presence of bruising/abrasions in the distribution of a seatbelt (i.e. horizontal and/or diagonal) across the abdomen, chest and sometimes neck. 

A positive seatbelt sign, in combination with abdominal pain or tenderness, results in a higher likelihood of intra-abdominal injuries, in particular bowel/mesenteric injury 1,3.
