Abstract
We reviewed our experience with proximal pulmonary artery aneurysm (PPAA) to determine whether accurate preoperative evaluation (crucial to differential diagnosis and surgical planning) had been obtained on the basis of CT study alone. Three patients with PPAA were studied with contrast-enhanced CT. We evaluated the size and shape of PPAAs, their proximal and distal extent, eventual presence of intraluminal thrombi, dissection, perianeurysmal fibrosis, and rupture. The results were compared with surgical findings. In two patients the aneurysm involved the pulmonary trunk and both the right and left arteries origin. In one patient the aneurysm extended from the left artery origin to the hilum of the left lung. Contrast-enhanced CT alone allows detection of aneurysm in the pulmonary trunk, in right or left pulmonary arteries with precise preoperative evaluation of the extent, size, shape, and complications. The CT imaging was unable to establish the etiologic origin and presence of small intimal tears in PPAA.
