In the roll call of neurological diseases from which horses can suffer, there is one many horse owners don't yet know about–cauda equina syndrome. Caused by myriad infectious, inflammatory, and/or traumatic factors, the syndrome includes many hind-end neurological clinical signs stemming from damage to the cauda equina, the tapered end of the spinal cord along with the extensions of spinal nerve roots extending alongside and past it. Scott Pirie, BVM&S, PhD, CertEP, CertEM, MRCVS, described cauda equina syndrome in depth at the 2004 British Equine Veterinary Association Congress, held Sept. 15-18 in Birmingham, U.K.

As a result of the inflammation associated with this condition, the sacrococcygeal spinal nerve roots (one of which is highlighted), seen emerging from the dura covering the terminal spinal cord, are markedly swollen.
