A 75-year-old woman was referred with a long history of dysphagia and wheezing. A chest radiograph revealed the presence of bilateral paratracheal stripes of abnormal appearance (fig 1).

Computed tomography angiography with 64 detectors (64-DCTA) of the chest revealed the presence of a right-sided aortic arch with an aberrant retro-oesophageal left subclavian artery arising from a Kommerell’s diverticulum (fig 2).

The left (small white arrow) and right (black arrow) common carotid arteries arise from the ascending aorta as the first and second epiaortic branches, respectively. The right subclavian artery (curved arrow) arises as the third epiaortic | |||||||||
