Saphenous vein graft aneurysms (SVGA) incidental finding. A: initial chest X-ray with the incidental finding of a mass (arrow indicated) silhouetting the heart; B: initial computed tomography coronary angiography showing a pseudo-aneurysm (arrow indicated) of the saphenous vein grafts from the aorta to obtuse marginal artery (SVG-OMA) bypass with a maximum diameter of 66 mm and extensive thrombosis, as there is minimal contrast within its lumen.

Figure 2.

Saphenous vein graft aneurysms (SVGA) ten-year post-diagnosis imaging evaluation. A: chest X-ray 10 years after Figure 1A depicting pleural effusion in the lower two-thirds of the left hemithorax (star indicated), obscuring the mass; B: computed tomography coronary angiography (CTCA) performed 10 years after Figure 1B showing an increase in the pseudo-aneurysm size to 94 mm (arrow indicated), and suspected left hemothorax; C and D: CTCA 3D multiplanar reconstruction demonstrating a giant SVGA (arrow indicated) in close relation with lateral and posterior left ventricular walls.
