Spinal tumors are neoplasms located in the spinal cord. Extradural tumors are more common than intradural neoplasms.

Depending on their location, the spinal cord tumors can be:

Extradural tumors are mostly metastases from primary cancers elsewhere (commonly breast, prostate and lung cancer). Intradural tumours can be classified as intramedullary (within the spinal parenchyma) or extramedullary (within the dura, but outside the spinal parenchyma). Extramedullary tumours are more common than intramedullary tumours. Common extramedullary tumours include meningiomas, schwannomas, extramedullary ependymomas, haemangioblastomas, while intramedullary tumours include astrocytomas and intramedullary ependymomas.

Pain is the most common symptom at presentation. The symptoms seen are due to spinal nerve compression and weakening of the vertebral structure. Incontinence and decreased sensitivity in the saddle area () are generally considered warning signs of spinal cord compression by the tumor. Other symptoms of spinal cord compression include lower extremity weakness, sensory loss, numbness in hands and legs and rapid onset paralysis. The diagnosis of primary spinal cord tumors is very difficult, mainly due to its symptoms, which tend to be wrongly attributed to more common and benign degenerative spinal diseases.

Spinal cord compression is commonly found in patients with metastatic malignancy.Back pain is a primary symptom of spinal cord compression in patients with known malignancy. It may prompt a bone scan to confirm or exclude spinal metastasis. Rapid identification and intervention of malignant spinal tumors, often causing spinal cord compression, is key to maintaining quality of life in patients.
