70-year-old male presented hoarseness and mediastinal mass. Scout CT shows a left sided mediastinal mass. The aortic knob left main stem bronchus and pulmonary branches can be seen – “hilum overlay” sign, indicating that the mass is not arising from the lung parenchyma. There is elevation of the left hemidiaphragm secondary to left phrenic nerve palsy.

?Traumatic in Origin
Axial CT with contrast shows a left sided aneurysm off the aortic arch with a large thrombus in the aneurysm. The neck of the aneurysm is relatively wide. The location of the aneurysm raises the possibility that the aneurysm may have been traumatic in origin. Additionally, there is a lack of significant atherosclerosis.

Post Endograft Repair
Axial CT with contrast shows a left sided aneurysm off the aortic arch s/p repair with an endograft with a large residual thrombus in the aneurysmal sac (a, white arrowhead). Within the left subclavian artery (LSA) there is an Amplatzer device (b, white ring) which occludes the LSA at its origin. The patient had a left carotid to LSA graft to enable flow to the left upper limb. There is elevation of the left hemidiaphragm secondary to left phrenic nerve palsy. .
