A 51-year-old male who had received hemodialysis twice a week was referred to our hospital for a further examination of bloody pleural effusion in the right chest. He has been suffering from a fever and cough for 2 months. Chest computed tomography and magnetic resonance imaging revealed a pleural effusion in the right pleural cavity and posterior mediastinal tumor in paravertebral lesion. Chest drainage was performed, and cytological diagnosis did not show malignant findings. To make a definite diagnosis and treatment, surgical resection was carried out. During surgery, posterior mediastinal tumor originated from vagal nerve, and a schwannoma was diagnosed by frozen section. After resection, postoperative course was uneventful, and bloody pleural effusion disappeared.
