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).
