We report a case of a 40-year-old female patient presenting with dysphagia and retrosternal chest pain for three years caused by a retroesophageal aberrant left subclavian artery originating from an aneurysmatic dilatation (Kommerell's diverticulum). The aortic arch and descending thoracic aorta were right-sided. Diagnosis was established by esophagogram, computed tomography and magnetic resonance angiography. The patient was very responsive to clinical treatment and she is presently being followed-up in the outpatient clinic for over one year.
