Summary
This case report details the first canine intraspinal synovial cyst, a rare condition causing hind limb weakness. Surgical removal led to a full recovery in a Siberian husky cross.
Area of Science:
- Veterinary Neurology
- Neurosurgery
- Pathology
Background:
- Intraspinal synovial cysts are rare, with limited reports in veterinary literature.
- Canine spinal cord compression can result from various extradural lesions.
Observation:
- An eight-year-old male Siberian husky cross presented with acute pelvic limb ataxia and paraparesis.
- Spinal imaging revealed extradural compression at the T13-L1 vertebrae.
- Histopathology confirmed an extradural cystic lesion as a synovial cyst with chondromatosis.
Findings:
- Surgical decompression via hemilaminectomy successfully removed the intraspinal synovial cyst.
- The dog experienced a marked improvement in neurological function post-surgery.
- No postoperative complications were noted, with a complete recovery at two years.
Implications:
- This case represents the first documented instance of an intraspinal synovial cyst in a dog.
- Highlights the importance of considering synovial cysts in the differential diagnosis for canine spinal cord compression.
- Demonstrates the efficacy of surgical intervention for this condition, leading to excellent long-term outcomes.
