Syrinx terminology

There are specific terms used when describing a syrinx or other cystic lesions within the spinal cord:

  • hydromyelia: fluid accumulation/dilatation within the central canal, therefore, lined by ependyma
  • syringomyelia: cavitary lesion within cord parenchyma, of any cause (there are many); located adjacent to the central canal, therefore not lined by ependyma
  • syringohydromyelia: term used for either of the above, since the two may overlap and cannot be discriminated on imaging
  • hydrosyringomyelia: same as syringohydromyelia
  • syrinx: common name for the cavity in all of the above
