Syringomyelia (SM)

A chronic progressive disease of the spinal cord characterized by the development of fluid-filled cavities of surrounding tissues. Cavitation can occur in any area of the spinal cord. It can involve pathways of the cord that carry impulses of pain and temperature sensations resulting in sensory losses. Pain and paresthesia also occur. Destruction of lateral and anterior gray matter in the cord causes muscular atrophy, spastic paralysis, and weakness. Scoliosis is often found in association with SM.
