A fluid-filled lesion forms, known as a syrinx. [1] This can vary in size significantly between patients. [1] Nerve fibres may be compressed where they cross the midline, or in other parts of the spinal cord. [1] Cranial nerves may be affected. [3] Syringobulbia may be associated with syringomyelia, a syrinx limited to the spinal cord. [4]
The combination of symptoms varies from one patient to another depending on the location of the syrinx within the spinal cord, as well as its extent. Syringomyelia has a prevalence estimated at 8.4 cases per 100,000 people, [ 5 ] with symptoms usually beginning in young adulthood.
A syrinx is suggested by an unexplained central cord syndrome or other characteristic neurologic deficits, particularly pain and temperature sensory deficits in a capelike distribution. MRI of the entire spinal cord and brain is done. Administration of intravenous Gadolinium during the MRI examination is useful for detecting any associated tumor.

Syringomyelia is often associated with type I Chiari malformation and is commonly seen between the C-4 and C-6 levels. The exact development of syringomyelia is unknown but many theories suggest that the herniated tonsils in type I Chiari malformations cause a "plug" to form, which does not allow an outlet of CSF from the brain to the spinal canal.

In the mid-1970s, he opened the first U.S. based private diagnostic imaging center that featured a whole body CT scanner for clinical use. In 1981, he performed the world's first MRI clinical studies on patients. [5] Ross's medical research includes brain damage in boxers and the MRI evaluation of diseases of the breast. [6]
