Summary
A cat with acute spinal cord injury due to nucleus pulposus extrusion recovered with conservative treatment. Later, the same cat developed spinal arachnoid diverticulum, successfully treated with surgery.
Area of Science:
- Veterinary Neurology
- Comparative Medicine
- Spinal Cord Diseases
Background:
- Recurrent spinal cord issues can affect feline patients.
- Accurate diagnosis through advanced imaging is crucial for effective treatment.
Observation:
- A one-year-old cat experienced acute tetraparesis from a C3-C4 nucleus pulposus extrusion, treated conservatively with full recovery.
- Five years later, the same cat presented with chronic ataxia and tetraparesis.
Findings:
- Initial magnetic resonance imaging (MRI) revealed acute non-compressive nucleus pulposus extrusion at C3-C4.
- Follow-up MRI showed a spinal arachnoid diverticulum at C3, causing significant spinal cord compression.
- Surgical intervention (hemilaminectomy and durectomy) resolved the arachnoid diverticulum.
Implications:
- This case highlights the possibility of recurrent or new spinal pathologies in cats.
- Conservative management can be effective for acute nucleus pulposus extrusion.
- Surgical treatment of spinal arachnoid diverticulum offers a positive prognosis in feline patients.
