Cauda Equina Traction - in small animals
:Tail pull injury
:Esp. cats after RTA
:Lesion via longitudinal traction
:Sacrocaudal dislocation/fracture
:Limp tail
:Incontinence
:Hindlimb Paresis
:Diagnosis on Clinical signs and history
:+/- Radiographs to show dislocation/fracture
:Prognosis difficult to predict
:Poor prognosis if tail limp & no anal tone
:Supportive treatment
:Persist for >3 months if possible
Cauda Equina Neuritis - large animals
:Equine version of Idiopathic polyradiculoneuritis
:Extradural nerve roots of cauda equina thickened and discoloured
:Inflammatory infiltrate (lymphocytes, plasma cells, macrophages)
:Extensive axonal damage and demyelination
:Cranial nerve involvement often occurs
:Aetiology unknown:
:Antecedent infection?
:Antibodies to PNS myelin?
:Paralysis & anaesthesia of tail
:Urinary incontinence
