- Signalment: 2-year-old male intact Pug named Bosley
- Presenting Complaint: Bosley presented to the MissionVet Specialty & Emergency Neurology Department for evaluation of chronic progressive non-ambulatory paraparesis
- Bosley started having difficulty walking in February or March 2018 when he was around 8 months old
- Signs started with ataxia and dragging pelvic limbs
- He was not apparently painful
- Treatment with steroids helped, but signs were progressive
- He lost the ability to walk in the Fall of 2019
- Mentation was alert and appropriate
- Non-ambulatory paraparetic with spastic movement in the pelvic limbs when supported
- Postural testing in the pelvic limbs was abnormal including absent knuckling (both 0) and absent hopping in the pelvic limbs (both 0)
- Postural reactions in the thoracic limbs were normal
- Thoracic limb reflexes were normal
- Cranial nerve exam was normal
- No apparent spinal pain with deep palpation at any level
Neuroanatomical Localization: T3-L3 myelopathy
- Intervertebral Disk Disease (IVDD)
- Meningitis (autoimmune vs infectious)
- Congenital Malformation
Spinal Radiographs (taken May 2018):
MRI (performed October 2019):
- Treatment Options:
- Decompressive surgery with spinal stabilization. (Owners elected to move forward with this option.)
- Continued medical management with steroids, wheelchair, etc.
- Guarded due to length of time affected and severity of clinical signs, however, it is unlikely he would have any improvement without surgical decompression.
- Treatment (performed October 2019):
- Surgical decompression via dorsal laminectomy over T5-7 with stabilization using threaded pins and PMMA.
- 2-Weeks Post-Op: Patient was weakly ambulatory with marked proprioceptive ataxia – still on steroids.
- 8-Weeks Post-Op: Patient was strongly ambulatory with moderate proprioceptive ataxia – still on steroids.
- 12-Weeks Post-Op: Patient remained strongly ambulatory with mild proprioceptive ataxia. Steroids were discontinued 2 weeks prior to this exam.
