Lumbar puncture was performed percutaneously through the L5-L6 interacuate foramen using a 22-gauge spinal needle into the subarachnoid space.
A neurological examination performed to determine the neuroanatomical localization and extent of the neurological lesions revealed multifocal involvement with the following signs: an alteration of consciousness and behaviour was observed; the patient was very anxious and disoriented with vocalisation and agitation.Rotational thromboelastometry (ROTEM) testing performed 3 days after the lumbar puncture showed the presence of a hypocoagulable state (Figure 2).MRI (Magnetic resonance imaging) was carried out on a T system with m T/m gradients and revealed an inflammatory process within the brain parenchyma (Figure 3).Proprioception was absent and spinal reflexes were exaggerated, bilaterally in both hind limbs. Neuroanatomical localization indicated a lesion in the T3-L3 spinal cord segment.
The degree of neurologic impairment was graded as 3/5 on the Sharp and Wheeler scale .Twelve hours after lumbar puncture, the dog displayed signs of multifocal central nervous system lesions (spastic tetraplegia, head tilt, nystagmus, amaurosis, myosis, altered consciousness, ataxic breathing pattern).
