Neoplasms of the spinal canal encompass a range of tumours 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. Tumours of vertebral bodies are discussed separately: see vertebral body tumours.
Spinal cord (intramedullary)
- spinal ependymoma
- spinal astrocytoma (diffuse)
- spinal pilocytic astrocytoma
- spinal haemangioblastoma
- spinal cord metastasis (intramedullary)
- spinal leptomeningeal metastases (these can mimic exophytic tumours)
- spinal primitive neuroectodermal tumours
- spinal lymphoma/leukaemia
- spinal ganglioglioma

Intradural extramedullary

Cauda equina and filum terminale
- myxopapillary ependymoma
- spinal nerve sheath tumours
- spinal paraganglioma
- spinal lymphoma/leukaemia
- metastases
