Right aortic arch with Kommerell’s diverticulum. a Illustration of a right aortic arch (black arrow) with a prominent Kommerell diverticulum (white arrow) in the proximal descending thoracic aorta (*), compressing the oesophagus (E). b Axial CT scan shows a right aortic arch (arrow) with a large Kommerell diverticulum (arrowhead) compressing the posterior oesophagus. c Coronal MIP image demonstrates a right aortic arch (arrow) and prominent Kommerell diverticulum (arrowhead) in the proximal descending thoracic aorta (*). d Reconstructed 3D volume-rendered image exquisitely demonstrates the right aortic arch (arrow) with a large Kommerell diverticulum (*) giving off the retroesophageal aberrant left subclavian artery (arrowhead). e Coronal CT image shows airway narrowing (arrow) caused by the vascular ring
