T1-weighted Spin Echo MR image (\"black blood\" technique) of the thoracic aorta at the level of the aortic arch demonstrates a 1.5-2.0 cm saccular aneurysm approximately 1.5 cm distal to the origin of the left subclavian artery. No dissection or rupture is identified. No additional vascular abnormalities are identified. Incidentally noted are bilateral nodular sub-pleural densities with a spiculated mass seen in the right posterior lung field.
