A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurri
ng as the result of a missed aortic lesion at the time of the initial injur
y. Therefore, clinical suspicion and careful abdominal exploration at first
laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its
risk of delayed rupture. We present a case of successful surgical treatmen
t of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-th
reatening gunshot wound in a 13-year-old child.
