A cardiac CT angiography (CTA) revealed that the size of the pulmonary artery was 31 x 26 x 25 mm, and the end of the pulmonary artery of the patent ductus arteriosus was 5.8 x 4.8 mm (Figure 2).
Surgical findings: (A) PAA bulge on the left side of the main pulmonary trunk (arrow); (B) appearance of aneurysm wall tissue.

After freeing the structures surrounding the pulmonary artery aneurysm, the aneurysm was seen to be approximately 30 mm in diameter and spherical in shape (Figure 3).
