Figure 1 Computed tomographic angiography on admission showed an ulcer-like projection in the descending thoracic aorta (left). Follow-up computed tomographic angiography indicated ulcer-like projection dilatation in the descending thoracic aorta (right).

Figure 2 Results of computational fluid dynamic calculations from computed tomographic angiographic data allow the vortex flow into the lesion to be visualized.

Figure 3 Results of computational fluid dynamic calculations from computed tomographic angiographic data show that the inflow rate into the ulcer-like projection lesion was 110 mL/min.
