Intraspinal tumors, also known as spinal cord tumors, include a general term for primary or metastatic tumors that occur in the spinal cord itself and in various tissues within the spinal canal adjacent to the spinal cord (such as nerve roots, dura mater, blood vessels, adipose tissue, congenital embryonic remnants, etc.). Intraspinal tumors can compress the spinal cord and nerve roots, causing motor and sensory impairment of the limbs, which can lead to paralysis in severe cases.
