Schematic illustration of the mediastinal structure of the present case. The trachea and esophagus were encircled completely by the right aortic arch. The ductus arteriosus connected Kommerell’s diverticulum to the pulmonary artery. The left recurrent laryngeal nerve passes behind the ductus arteriosus and ascends posteriorly. RAA: right aortic arch, KD: Kommerell’s diverticulum, DA: ductus arteriosus, LRLN: left recurrent laryngeal nerve, LVN: left vagus nerve, LSA: left subclavian artery, LCA: left common carotid artery, RSA: right subclavian artery, RCA: right common carotid artery, PA: pulmonary artery, E: esophagus, T: trachea
