Syringomyelia refers to a cystic collection that occurs within the spinal cord around the central canal

The term can apply to any cavity within the substance of the spinal cord that may or may not communicate with the central canal (ependyma does not line the cavity wall).

It is distinct from hydromyelia in which there is simply dilatation of the central canal.

In syringomyelia, there is a dissection of the ependymal lining of the central canal and CSF collection within the cord itself. Therefore, the collection does not have an ependymal lining.

It is very difficult to distinguish hydromyelia from syringomyelia and hence, the collective terms hydrosyringomyelia or simply "syrinx" are sometimes used to refer to a fluid collection within the cord.
