Degenerative myelopathy in a cat
Journal of the American Veterinary Medical Association
|January 1, 1980
Summary
Degenerative myelopathy caused progressive hind limb weakness and loss of coordination in a cat. Microscopic analysis revealed spinal cord myelin degeneration, but the exact cause remained undetermined.
Area of Science:
- Veterinary Neurology
- Comparative Pathology
Background:
- Degenerative myelopathy (DM) is a progressive neurological disease affecting the spinal cord.
- Early diagnosis and understanding of DM pathogenesis are crucial for affected animals.
Observation:
- A 6-year-old cat presented with progressive ataxia and posterior paresis over 8 months.
- Loss of conscious proprioception was noted in the affected cat.
- Corticosteroid treatment failed to improve clinical signs.
Findings:
- Microscopic examination of the spinal cord showed diffuse myelin degeneration.
- Marked astrocytosis was present, indicating a reactive glial response.
- The degenerative lesions were most severe in the thoracolumbar spinal cord segment.
Implications:
- This case highlights the clinical presentation of degenerative myelopathy in a feline patient.
- The unidentified etiology in this case warrants further investigation into potential causes of feline DM.
- Understanding feline DM can aid in developing diagnostic and therapeutic strategies for similar neurological conditions.
