Summary
Spinal synovial cysts can cause myelopathy in dogs. Surgical removal led to improved mobility and neurological function in all nine dogs studied.
Area of Science:
- Veterinary Neurology
- Comparative Pathology
Background:
- Spinal synovial cysts are rare extradural compressive lesions.
- Degenerative changes in articular facets or intervertebral discs are often associated with these cysts.
Observation:
- Nine dogs with cervical or thoracolumbar myelopathies were diagnosed with extradural spinal synovial cysts.
- Two distinct canine populations were identified: young, giant breeds with cervical cysts and older, large breeds with thoracolumbar cysts.
- Synovial cysts were the primary cause of spinal cord compression in some cases.
Findings:
- All dogs underwent successful decompressive surgery with histopathological confirmation of synovial cysts.
- Cerebrospinal fluid analysis revealed albuminocytological dissociation in six dogs, indicating chronic compressive myelopathy.
- Post-operative follow-up showed full ambulation and improved neurological function in all patients.
Implications:
- Surgical decompression is an effective treatment for spinal synovial cysts in dogs.
- Early diagnosis and intervention can lead to favorable neurological outcomes.
- Understanding the distinct presentations in different canine breeds is crucial for diagnosis and treatment.
