It is characterized by 3 lumens separated by 2 intimal flaps, resembling the appearance of the 'Mercedes Benz' sign. We present an unusual case of triple barreled aortic dissection in a 71-year-old patient with history of hypertension. Chest radiography showed a widened mediastinum. The CT images showed a thoraco-abdominal type B aortic dissection with three lumens giving the appearance of the 'Mercedes Benz' sign. As the CT-scan showed no complications of the aortic dissection, the patient received medical conservative treatment.
