Syringomyelia (se-ringo-my-EEL-e-ah) is a cyst in the center of the that is filled with fluid.

The cyst, also called a syrinx (se-rinks), can form anywhere along the spinal cord. It can get larger and longer over time. This puts pressure on the spinal cord. The pressure can cause symptoms. If not treated, over time it may cause nerve damage.

What causes syringomyelia?

Often, a cyst forms because of a condition that changes the normal flow of . The CSF can build up in the spinal cord and form a cyst.

Children who have other problems involving the brain and spinal cord often have syringomyelia, too. Many times, these related problems are present when a baby is born (congenital), such as:

Not all children with these conditions develop syringomyelia. Sometimes there is no clear cause.

  • An  scan of your child’s spine to look for the cyst.
