Kommerell Diverticulum with Aberrant Right Subclavian Artery Causing Esophageal Compression: A Rare Case

Abstract

Kommerell diverticulum refers to the bulbous configuration of the origin of an aberrant left subclavian artery. It was originally described as a diverticular out - pouching at the origin of an aberrant right subclavian artery with a left-sided aortic arch. This is alsoassociated with a right - sided aortic arch. We report a case of a 66 year old female who presented with chronic cough. Clinico-radiological evaluation demonstrated anaberrant right subclavian artery with Kommerelldiverticulum. There was focal compressionof the esophagus and proximal dilatation. This probably caused regurgitation of fluid leading to persistent cough. Symptoms improved with medical management and she is under regular follow-up.
