چکیده
A 35-year-old woman was admitted to our hospital with an abnormal shadow on her chest roentgenogram. Computed tomography showed that a tumor was located in the right upper mediastinum. Resection of the tumor by video-assisted thoracoscopic surgery was performed. Operative findings determined that the tumor originated from the right vagus nerve and was diagnosed as schwannoma by pathological examination.
