Summary
This study reports the first case of a dog experiencing cervical intradural/extramedullary intervertebral disc extrusion (IVDE). This condition caused progressive tetraparesis and was diagnosed using MRI and surgical findings.
Area of Science:
- Veterinary Neurology
- Canine Spinal Surgery
- Diagnostic Imaging in Veterinary Medicine
Background:
- Subacute progressive asymmetrical tetraparesis and cervical hyperesthesia are significant neurological deficits in dogs.
- Intervertebral disc extrusion (IVDE) is a common cause of spinal cord compression, typically presenting as an extradural or intramedullary lesion.
- Intradural/extramedullary IVDE is a rare form of disc extrusion, presenting unique diagnostic challenges.
