A 46-year-old man was admitted to our hospital because of an abnormal shadow on the chest roentgenogram. The operation was performed through left posterolateral thoracotomy. A tumor mass, 4.5 x 2.5 x 2.5 cm in size, was found and its origin was the left main vagal nerve 0.5 cm distal the branching root of the recurrence nerve. The tumor and a part of the left vagal nerve was resected en bloc. Pathological study revealed tha the tumor was neurinoma of Antoni A+B. Postoperative course was uneventful. This is the 34th reported case in Japanese literature of neurinoma with its origin from the intrathoracic vagal nerve.
