A case of vagal nerve neurinoma with nerve preservation by video-assisted thoracic surgery

Abstract

A 60-year-old man was referred to our hospital due to an abnormal shadow found on a chest radiograph. His chest CT scan showed a cystic tumor in the left upper mediastinal area. The preoperative diagnosis was neurinoma originating from the mediastinal vagal nerve. Video-assisted thoracic surgery was performed. The tumor arose from the mediastinal vagal nerve proximal to the recurrent laryngeal nerve, and tumor resection was performed. The histological diagnosis was neurinoma. His postoperative course was uneventful, and we could preserve the function of the recurrent laryngeal nerve.
