A 42-year-old female was noted to have a mediastinal mass on routine chest roentgenogram. She was asymptomatic and physical examination was unremarkable. Computed tomography of the chest confirmed the presence of a 3.5 cm well circumscribed mass in the middle mediastinum adjacent to the aortic arch. Operation was performed. A solitary middle mediastinal tumor was readily apparent at the aortic arch to the left subclavian artery, originating from the vagus nerve superior to the take-off of the recurrent laryngeal nerve. Excision was possible by enucleation of the mass. The postoperative period was uneventful, although there was paralysis of the left vocal cord as evidenced by hoarseness. Histologically the diagnosis of a schwannoma of the vagus nerve was made.
