Understanding Most Common Spinal Cord Tumors Understanding Most Common Spinal Cord Tumors Spinal cord tumors are abnormal growths that develop within or surrounding the spinal cord and its protective membranes. Although they are relatively rare compared to other types of tumors, understanding these growths is essential for early diagnosis and effective treatment. These tumors can be classified based on their location, origin, and whether they are benign or malignant.
Typically, spinal cord tumors are categorized into primary and secondary types. Primary tumors originate directly from the tissues within the spinal cord or its immediate surroundings, such as the meninges, nerve roots, or supportive cells. In contrast, secondary tumors, also known as metastatic tumors, result from cancer cells that have spread from other parts of the body, like the lungs, breast, or prostate.
Among primary spinal cord tumors, some of the most common include intramedullary tumors, which occur within the spinal cord itself, and extramedullary tumors, which develop outside the spinal cord but within the dura mater, the tough outer membrane covering the spinal cord. Within these categories, specific tumor types such as ependymomas, astrocytomas, meningiomas, and schwannomas are frequently encountered.

Ependymomas are the most prevalent intramedullary tumors in adults and arise from ependymal cells lining the central canal of the spinal cord. They often grow slowly and may cause symptoms like pain, weakness, or sensory changes. Astrocytomas, another intramedullary tumor, originate from astrocytes, a type of supportive glial cell, and can vary in malignancy from low-grade to high-grade forms.
Meningiomas, constituting a significant portion of extramedullary tumors, develop from the meninges. These tumors are typically benign and grow slowly, often detected incidentally. Schwannomas, also called neurilemmomas, arise from Schwann cells that insulate nerve fibers, and they commonly affect the nerve roots, leading to pain, numbness, or weakness along the affected nerve’s path.

The symptoms of spinal cord tumors generally include localized pain, which may worsen at night, neurological deficits like weakness or numbness, difficulty walking, and in severe cases, loss of bladder or bowel control.
Diagnosis often involves imaging studies such as magnetic resonance imaging (MRI), which provides detailed views of the spinal cord and surrounding tissues. Biopsy may be necessary to determine the tumor’s nature and guide treatment decisions. Treatment options vary based on the tumor type, location, and malignancy degree. Surgical removal is often the primary approach, especially for accessible benign tumors. Radiation therapy and chemotherapy may be employed for malignant or unresectable tumors.
Early detection and intervention are crucial to prevent permanent neurological damage. Advances in neurosurgery and targeted therapies continue to improve outcomes for patients with spinal cord tumors. Multidisciplinary care involving neurologists, neurosurgeons, oncologists, and rehabilitation specialists plays a vital role in optimizing recovery and quality of life.
