'''A myelogram of the lower cervical spine of a 16-year-old Thoroughbred mare which had shown progressive hindlimb ataxia over 18 months is illustrated.'''
<br />
<FlashCard questions="3">
|q1=What radiological abnormalities are present?
|a1=There is poor definition of the intervertebral facet joints between cervical vertebrae C6 and C7, and almost complete obliteration of dorsal and ventral contrast columns at the same level.
|l1=
|q2=What is your diagnosis?
|a2=Stenosis of the cervical vertebral canal at the C6/7 level (cervical static malformation). <br><br>
A focal compressive myelopathy is relatively uncommon in a horse of this age, but, with this history, when it occurs, it usually involves static compression in the caudal cervical spine.
|l2=
|q3=What other conditions might cause similar signs?
|a3=
*Spinal trauma or infection;
*Polyneuritis equi (usually other signs of cauda equina syndrome);
*EHV-1 myeloencephalitis (usually sudden onset rather than progressive);
*Equine protozoal encephalomyelitis (if the mare is or has been on the American continent);
*Equine degenerative myeloencephalopathy (usually younger horses – forelimbs usually affected as badly as hindlimbs);
*Spinal or vertebral neoplasia.
|l3=
