Right aortic arch, otherwise cardiomediastinal contour is normal. Lungs and pleural spaces are clear.

Right aortic arch with retro-oesophageal aberrant left subclavian artery. Dilatation of its origin, consistent with a Kommerell diverticulum. 

Right aortic arch with Kommerell diverticulum. TEVAR from proximal aortic arch to mid descending thoracic aorta. Previous ligation of the first part of an aberrant left subclavian artery with left common carotid to left subclavian bypass. Peripheral filling of the Kommerell diverticulum is noted with a central filling defect.
