Neoplasms of the spinal canal encompass a range of tumors which arise from or involve the spinal cord, theca, and spinal nerves.
Pathology
These can be divided according to the tissue/structure of origin within the spinal canal. Tumors of vertebral bodies are discussed separately: see vertebral body tumors.
Spinal cord (intramedullary)
- spinal ependymoma
- spinal astrocytoma (diffuse)
- spinal pilocytic astrocytoma
- spinal hemangioblastoma
- spinal cord metastasis (intramedullary)
- spinal leptomeningeal metastases (these can mimic exophytic tumors)
- spinal primitive neuroectodermal tumors
- spinal lymphoma/leukemia
- spinal ganglioglioma

Intradural extramedullary

Cauda equina and filum terminale
- myxopapillary ependymoma
- spinal nerve sheath tumors
- spinal paraganglioma
- spinal lymphoma/leukemia
- metastases
