A 25-year-old female was admitted in April, 1981 because of two abnormal shadows on a chest film. Under a preoperative diagnosis of benign tumors of the chest wall and upper mediastinum, right thoracotomy was carried out. An encapsulated tumor arising from the right vagal nerve and another tumor arising from the third intercostal nerve were found and the vagal nerve and the third intercostal nerve were transected to remove the tumors. Postoperative clinical course was uneventful. The pathological diagnosis of both tumors was neurofibroma.
Based on the literature previously reported, mediastinal neurofibroma arising from the vagal nerve is extremely rare and this case is only the second one reported in Japan.
