Journal of the American Veterinary Medical Association
|June 30, 2020
Summary
A dog with neurological signs was diagnosed with an intradiploic epidermoid cyst. Surgical removal led to complete recovery, suggesting a good long-term prognosis for this condition in dogs.
Area of Science:
- Veterinary Neurology
- Neurosurgery
- Diagnostic Imaging
Background:
- Intradiploic epidermoid cysts are rare intracranial masses.
- Clinical presentation can include seizures, dullness, and vomiting.
Observation:
- A 10-year-old Shih Tzu presented with acute neurological signs including seizures.
- Physical examination revealed a soft, dome-shaped mass in the occipital region.
- Radiography, CT, and MRI confirmed an intra- and extracranial mass compressing the cerebellum.
Findings:
- Surgical excision of the mass was performed.
- Histopathology confirmed an intradiploic epidermoid cyst.
- Post-operative neurological deficits resolved within 3 weeks.
Implications:
- Complete surgical removal of intradiploic epidermoid cysts in dogs can lead to excellent long-term outcomes.
- This case highlights the importance of advanced imaging for diagnosis and surgical planning.
- Early diagnosis and intervention are crucial for managing canine intracranial masses.
