Abstract
Introduction: Kommerell diverticulum (KD), a rare embryological variant, is an aneurysm of aortic arch at the origin of an aberrant subclavian artery (ASA). It is usually asymptomatic and detected incidentally on imaging studies or postmortem. Common symptoms include dysphagia (dysphagia lusoria) and chest pain. The most common complications include rupture due to an enlarged diverticulum. Surgical correction of the diverticulum and repair of aorta and aberrant subclavian artery is the treatment of choice.
Case Report: A case of Kommerell diverticulum in a 68-year-old female with right aortic arch with large left sided KD was found incidentally on imaging studies.
Conclusion: Subtle findings on a chest X-ray may help in diagnosis of KD. Vascular anomalies such as KD should be considered as differential diagnosis in patients with chronic cough or dysphagia when other causes have been ruled out.

Keywords: Aberrant subclavian artery, Carotid body tumor, Dysphagia lusoria, Kommerell diverticulum, Right sided aortic arch
