[Multiple schwannoma of the intrathoracic vagal nerve; report of a case].

A 67-year-old male referred to our hospital for the close examination of abnormal chest X-ray findings. Chest X-ray films showed abnormal shadows in the right lung field. Chest computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed the 3 tumors which located in superior, middle and posterior mediastinum. The operation underwent under the diagnosis of neurogenic tumors originating from the right intrathoracic vagal nerve. At the operation, the tumors existed the vagal nerve distal to the recurrent laryngeal nerve and they were resected with the transection of vagal nerve. The masses were histologically diagnosed as schwannoma. We reported a rare case of multiple schwannoma arising from the intrathoracic vagal nerve. He had no postoperative complications, and he has been free from recurrence for 4 years postoperatively.
