Syringomyelia

(Also known as “neck scratcher’s disease”)

What is Syringomyelia (SM)?

SM is a condition in which fluid-filled cavities develop within the spinal cord near the brain. In essence, the dog’s skull tends to be too small to contain the cerebellum (part of the brain that is used to coordinate voluntary movements). As a result, the cerebellum is forced through the foramen magnum (the hole at the back of the skull) which causes partial blocking of the cerebrospinal fluid. This disorder can be quite serious in that it can damage different areas of the spinal cord.

Symptoms

SM will commonly cause the dog to scratch obsessively in the neck and shoulder area. The dog will also be subject to severe pain in this area as well. As this disease continues, the animal may experience difficulties walking. Symptoms of this disorder do not typically show any signs until six months of age or later.

Causes

This disorder is inherited and very common in Cavalier King Charles Spaniels.

Treatment and Prevention

Surgery is the only way to correct this disorder, however it can be quite expensive and only performed by specialists. Medication can only be used to relieve some of the pressure of the built up spinal fluid, but will not ultimately cure the problem. The best method of prevention is not breeding carriers of this disease. Be sure to consult with your vet regarding any further information concerning SM.
