Intradural Extramedullary Tumor: Thoracic
Spinal cord tumors are relatively rare lesions, of which approximately 50% are intradural and extramedullary. The optimal treatment of these lesions is a gross total surgical resection with the traditional approach being through a posterior laminectomy. However, in cases where the tumors are located either lateral or anterior, or both, the laminectomy itself may not provide sufficient access to achieve total resection with a high degree of safety. Numerous other approaches to these tumors have been described and previously published which are outside the scope of this chapter. Enhancements available for intradural tumor surgery include newer neurophysiological tools, intraoperative ultrasound, and various devices including tumor aspirators and lasers. Combined with advances in preoperative imaging, these modalities of treatment offer a greater margin of safety and a larger opportunity for total resection and long-term cure from these lesions.
