Anomalies of the aortic arch associated with Kommerell diverticulum (KD) are rare congenital malformations. Symptomatic thoracic vascular rings presenting in adults are rare. We report a case of a 39-year-old woman who was diagnosed with uncontrolled asthma. She was complaining of worsening respiratory symptoms with dysphagia. Imaging studies and preoperative findings concluded to type II congenital anomaly of the aortic arch or Neuhauser's anomaly: a right-sided aortic arch with aberrant left subclavian artery, tracheoesophageal compression by KD and ligamentum arteriosum (LA). This compression was relieved by the resection of the LA and KD.
