Spinal Tumors

Spinal tumors are neoplasms located in the spinal cord. Extradural tumors are more common than intradural neoplasms.
Depending on their location, the spinal cord tumors can be:
Extradural - outside the dura mater lining (most common)
Intradural - part of the dura 
  o Intramedullary - inside the spinal cord
  o Extramedullary- inside the dura, but outside the spinal cord
