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:
Pathology
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.
Symptoms
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 (buttocks) 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.
Diagnosis
The diagnosis of primary spinal cord tumors is difficult, mainly due to their symptoms, which in early stages mimic more common and benign degenerative spinal diseases. MRI and bone scanning are used for diagnostic purposes. This assesses not only the location of the tumor(s) but also their relationship with the spinal cord and the risk of cord compression.
Treatment
numbness in the legs and arms, Some suggest that direct decompressive surgery combined with postoperative radiotheranumbness in the legs and arms,py provide better outcomes than treatment with radiotherapy alone for patients with spinal cord compression due to metastatic cancer. It is also important to take into consideration the prognosis of the patients and their ambulation status at diagnosis, and treat accordingly.
