"Although syringomyelia is distinct from hydromyelia, in which there is simply dilatation of the central canal, it is very difficult to distinguish the two on imaging. Hence, the collective terms hydrosyringomyelia or syringohydromyelia can also be used to describe this fluid collection within the cord."

"Syringomyelia applies 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). 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."

"Characteristically, the syrinx is in the cervicothoracic cord, with C2 to T9 being the most common location, however, the lesion may descend all the way down to the conus medullaris. There are numerous causes and associations, and these are discussed in more depth in the general article on syrinx."
