Chest radiograph showed a mediastinal mass abutting the left cardiac contour (Figure 1).
Three-Dimensional Computed Tomography Reconstruction of Giant Aneurysm. A three-dimensional volume rendered computed tomography image demonstrating the connection between the aorta and the giant left main coronary artery aneurysm is shown (unlabeled white arrow). The right coronary artery (RCA, arrow) was dilated and supplied most of the left coronary circulation territory.

Chest computed tomography identified the mass as a giant (9x8cm) aneurysm of the left main coronary artery (Figure 2).
Computed Tomography Images of Giant Aneurysm. The largely thrombosed aneurysm with a small patent lumen (*) is shown in the sagittal plane (panel A). The lumen (*) of the aneurysm communicates (white arrow) with the aorta (Ao, panel B). The giant aneurysm exerts mild compression on the main pulmonary artery (MPA, panel C). LV= left ventricle
