A Case of Right Sided Aortic Arch with Kommerell Diverticulum

Introduction: Kommerell diverticulum, a rare embryological variant, is an aneurysm of aortic arch at the origin of an aberrant subclavian artery. It is usually asymptomatic and detected incidentally on imaging studies or postmortem. Common symptoms include dysphagia and chest pain. The most common complications include rupture due to an enlarged diverticulum. Case Report: We present a male patient evaluated for chronic chest pain following traumatic blunt injury, who was incidentally found to have right sided aortic arch with kommerell diverticulum. Conclusion: Basic investigations like chest X-ray helps in clinching the diagnosis. Vascular anomalies like kommerell diverticulum should be considered as differential diagnosis in the evaluation of chronic cough, dysphagia, dyspnea.
