|Syringomyelia cyst (syrinx) in the spinal cord|
Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst may enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms.
Syringomyelia has several possible causes, though the majority of syringomyelia cases are associated with Chiari malformation, a condition in which brain tissue protrudes into your spinal canal. Other causes of syringomyelia include spinal cord tumors, spinal cord injuries and damage caused by inflammation around your spinal cord.
If syringomyelia isn't causing any problems, monitoring the condition may be all that's necessary. But if you're bothered by symptoms, you may need surgery.
