Frequent question: What are lesions on the brain and spine?

Lesions on the spine and in the brain indicate damage to the myelin that protects nerve cells. This is a sign of MS. One function of myelin is to help the nerves send impulses. Without myelin, the nerves’ impulses travel more slowly.

Are spinal lesions common?

Intracranial (brain) tumors account for 85-90% of all primary central nervous system (CNS) tumors. Primary tumors arising from the spinal cord, spinal nerve roots and dura are rare compared to CNS tumors that arise in the brain. Overall prevalence is estimated at one spinal tumor for every four intracranial lesions.

Is a lesion a tumor?

A bone lesion is considered a bone tumor if the abnormal area has cells that divide and multiply at higher-than-normal rates to create a mass in the bone. The term “tumor” does not indicate whether an abnormal growth is malignant (cancerous) or benign, as both benign and malignant lesions can form tumors in the bone.

What does MS do to your spine?

Multiple sclerosis (MS) is a condition of the central nervous system. People with MS experience damage to the outer coating of the nerve fibres that carry messages (nerve impulses) from the brain along the spinal cord and to the rest of the body. This coating is called the myelin sheath.
