[Spinal Cord Tumors:Classification, Treatment, and Prognosis].

Spinal cord tumors are classified into three types according to the site of origin: epidural tumors, intradural extramedullary tumors, and intramedullary tumors. It is important to understand the common tumors at each site. Most intradural extramedullary tumors are benign schwannomas or meningiomas and need surgical removal. For intramedullary tumors, it is important to determine the type of tumor and the site of origin before selecting the surgical approach.
