Simultaneous Bilateral Video-Assisted Thoracoscopic Surgery in the Prone Position for Resection of a Large Middle Mediastinal Tumor: A Case Report.

Schwannoma is the most common type of neurogenic tumor in the thorax and is typically benign. This article describes the case of a 64-year-old asymptomatic woman with abnormal findings on a chest X-ray examination. Preoperative enhanced computed tomography showed the presence of a middle mediastinal tumor measuring 7.4 cm protruding into both thoracic cavities. The mass was adjacent to the posterior aspect of the trachea. The esophagus was compressed to the right, indicating the potential appearance of symptoms in the future. Consequently, we performed simultaneous bilateral video-assisted thoracoscopic surgery in the prone position, achieving complete resection. Postoperative pathological examination revealed a benign schwannoma. Here, we report a case of a middle mediastinal tumor resected by a rarely utilized video-assisted thoracoscopic surgery (VATS) method.
