    Abstract:
    A 56 year-old female was pointed out an abnormal shadow on chest X-ray film for the lung cancer screening study. Chest X-ray film showed a round mass shadow at the right superior mediastinum. Chest CT scan revealed the mass was in the paravertebral area abutting on the 2nd thoracic vertebral body and had extended into the intervertebral foramen. Preoperative diagnosis was a dumb-bell-like neurogenic tumor. Operation was carried out by posterior approach in the prone position. At first thoracotomy was done by removing the paravertebral portion of the 2nd and 3rd ribs, and then hemilaminectomy was added. Both the intrathoracic and intraforminal portions of the tumor were completely exposed, and excised. Pathological examination demonstrated the tumor was a typical neurilemmoma originating from the 2nd intercostal nerve. When a neurogenic tumor of the posterior mediastinum has an intraspinal extension, a posterior approach by a simultaneous thoracotomy and laminectomy will be useful to remove the tumor at one sitting.
