This disorder is associated with syringomyelia, a syrinx limited to the spinal cord. Syringomyelia is present in 25% of patients with type I Chiari malformations. Syringomyelia is characterised by fluid filled cavities within the spinal cord. Fluid pressure may cause cysts to form in the spinal cord, a condition called syringomyelia. Syringomyelia is generally a chronic disorder that occurs over time, resulting in muscular atrophy. Physicians now use magnetic resonance imaging (MRI) to diagnose syringomyelia. Generally, there are two forms of syringomyelia&colon; congenital and acquired. Since the introduction of MRI, this test is rarely necessary to diagnose syringomyelia. MRI is safe, painless, and informative and has greatly improved the diagnosis of syringomyelia. Some cases of syringomyelia are familial, although this is rare. In the absence of symptoms, syringomyelia is usually not treated. The show highlighted issues involving syringomyelia in both the King Charles and Cavalier breeds. Surgery is not always recommended for syringomyelia patients. Facet joint injections are not indicated for the treatment of syringomyelia. An emerging concern is syringomyelia, although the incidence is currently unknown.
