Differentiation of aortic pseudoaneurysm from ductus diverticulum is critical, particularly in the trauma setting. The differentiation points are listed belowfollowing may be helpful to differentiate the two.
Aortic pseudoaneurysm
- location: often seen along the inferior surface of the aortic isthmus 1
. - angle with the aortic wall: acute angle
. - calcification: not present
. - other supportive findings: signs of regional traumatic injuries such as intimal flap or haematoma nearby within the aortic wall and/or mediastinum
.
Ductus diverticulum
- location: usually found at the anteromedial aspect of the aortic isthmus
.2 - angle with the aortic wall: often gentle obtuse angle
. - calcification: an important differentiating point when present
