'''A grey pony mare, born and bred in England, presented for a problem of the hindquarters. The pony was not particularly lame and had no history of lameness.'''

<br />

<FlashCard questions="3">
|q1=What abnormality is present?
|a1= There is marked atrophy of the gluteal muscles on the left hindlimb.
|l1=Equine Hindlimb - Anatomy & Physiology#Musculature
|q2=What is the likely cause, and might it have been different if the animal had spent time in the USA.
|a2=
*Muscle wastage as a result of disuse can be ruled out given the lack of a history of lameness. 
*Therefore, the problem must relate to denervation. 
*Trauma is unlikely, suggesting a systemic problem. 
*This is a slightly unusual case of polyneuritis equi (cauda equina neuritis). 
*In the USA, equine protozoal myeloencephalitis would have to be considered in such a case of focal neurogenic atrophy.
|l2=Polyneuritis Equi
|q3=What test is helpful in confirming this problem?
|a3=An ELISA has been developed to measure the increase in circulating antibodies to P2-myelin protein seen in cauda equina neuritis.
|l3=Polyneuritis Equi
