Most spinal tumors are extradural. Any type of tumor may occur in the spine, including lymphoma , leukemic tumors, myelomas, and others. A small percentage of spinal tumors occur within the spinal cord, most often consisting of ependymomas and other gliomas. The cause of primary spinal tumors is unknown. Some primary spinal tumors are associated with congenital or hereditary tendencies.
Spinal tumor is much less common than primary brain tumor .
The tumor affects the spinal-cord cells, nerve roots, meninges, blood vessels, or the bones of the spine. The symptoms vary depending on the location and type of the tumor and the general health of the person. Metastatic tumors often progress rapidly, while primary tumors are often slowly progressive over weeks to years. Spastic weakness may be present, with increased muscle tone and abnormal reflexes. Pain and temperature sensation may be lost simultaneously with or independently of other sensation losses.
