Cervical spinal arachnoid cyst in a dog
1Western College of Veterinary Medicine, University of Saskatchewan, Saskatoon.
Summary
An Akita dog experienced progressive neurological deficits due to an arachnoid cyst. Surgical cyst fenestration resulted in a near-complete recovery, resolving ataxia and proprioception loss.
Area of Science:
- Veterinary Neurology
- Neurosurgery
- Canine Medicine
Background:
- Arachnoid cysts are rare cerebrospinal fluid-filled sacs that can cause neurological dysfunction in dogs.
- Progressive ataxia and proprioceptive deficits in young dogs warrant thorough neurological investigation.
Purpose of the Study:
- To report a case of cervical arachnoid cyst in an Akita dog.
- To describe the diagnostic approach and surgical management of this condition.
- To evaluate the outcome following surgical intervention.
Main Methods:
- A detailed neurological examination was performed.
- Myelography was utilized to localize the spinal cord lesion.
- Surgical hemilaminectomy and cyst fenestration were performed at the C1-C2 vertebral level.
Main Results:
- Neurological deficits including ataxia, hypermetria, and loss of conscious proprioception were identified.
- Myelography confirmed a lesion consistent with an arachnoid cyst at the cervical vertebrae 1 and 2.
- The dog experienced a virtually full neurological recovery following surgery.
Conclusions:
- Cervical arachnoid cysts are a treatable cause of progressive neurological deficits in dogs.
- Surgical fenestration is an effective treatment option, leading to significant functional recovery.
- Early diagnosis and surgical intervention are crucial for optimal outcomes in canine spinal cyst cases.
