Classification of Spinal Tumors
Classification of Spinal Tumors
- Extradural
Classification of Spinal Tumors
- Extra-Medullary
Classification of Spinal Tumors
- Intra-Medullary
Most Common Intramedullary Spinal Tumor
Astrocytoma
Radiculopathy VS Myelopathy
Examples of Extradural Spinal Tumors
Source of Spinal Meningioma
Arachinoid Cells
Behaviour of Spinal Meningioma
Slow growing benign masses
Incidence of Spinal Meningioma
- Peak age: From 40-70 years.
- Sex: Female to Male ratio (4:1)
Location of Spinal Meningioma
- Mostly intradural - 5% extradural - 5% mixed
- Level: Thoracic (82%) Commenest = Cervical (15%) “ Lumbar (2%)
Origin of Spinal Schwanomma
Schwann cells of the sensory rootlets “The tumor only contains Schwann cells”
CP of Spinal Schwanomma
TTT of Spinal Schwanomma
Origin of Spinal Neurofibroma & neurofibromatosis
Fusiform expansion of the nerve (Schwann - perineural and neural cells)
Location of Spinal Neurofibroma & neurofibromatosis
- May be intradural, extradural or dumbbell
- Level: Occur more frequently in the cervicalspine in NF-1
TTT of Spinal Neurofibroma & neurofibromatosis
Difficult to get complete resection, why?
- Because of the extraforamenal extension and risk of functional loss
Origin of Spinal Ependymoma
- Ependymal lining of the central canal.
- Filum terminale “usually myxopapillary type”.
TTT of Spinal Ependymoma
Origin of Spinal Astrocytoma
Astrocyte (Supportive cells)
CP of Spinal Astrocytoma
- Presenting sign depend upon location.
- Most are grade lor Il
- Accompanying syrinx in 40%
