First vessel from the arch is the left commmon carotid artery. Bilateral calcified pleural plaques.
Thrombosed ligamentum arteriosum. Kommerell's diverticulum/dilatation of the origin of the left subclavian artery causes compression of the left brachiocephalic vein resulting in contrast entering the heart via alternative routes.
