Figure 2: (a) Transverse view of chest CT with contrast, showing aneurysmal dilatation of the proximal descending aorta at the level of the origin of the left subclavian artery. Maximum dimensions of the multi-lobulated aneurysm are 4.4 cm in the transverse dimension and 4.2 cm in the craniocaudal dimension. No periaortic fluid collections. There is mass effect from the pseudoaneurysm with anterior displacement of the carina, (b) Coronal view of chest CT with contrast, showing aneurysmal dilation of the proximal descending aorta. Notice the different densities in the aneurysmal area, (c) 3-D reconstruction of chest CT with contrast, showing aneurysmal dilatation before surgery
