Mercedes-Benz sign (aorta)

The Mercedes-Benz sign can be seen in aortic dissection on CT 1

It is seen as three distinct intimal flaps that have a triradiate configuration similar to the Mercedes-Benz logo (Figure 1). Two of the three lumens outlined by these intimal flaps belong to the false lumen of aortic dissection. The appearances are postulated to represent secondary dissection in the wall of the dissected false lumen. It is also called a triple-barrelled aortic dissection 2.
