Figure 1. A) 3D CT reconstruction demonstrating the aortic
pseudoaneurysm when initially diagnosed in communication with the former
aortic cannulation site. B) A further 3D CT reconstruction demonstrates
enlargement of the pseudoaneurysm observed twelve days later with
interval re-imaging
In addition to his remaining workup, an interval CT twelve days later
demonstrated an increase in the size of the pseudoaneurysm and
surrounding complex fluid collection in the anterior mediastinum.
Infectious etiology could not be out-ruled (Figure 1B, Figure 2).
