Summary
This study reports the first case of cerebral fibrocartilaginous embolism in a pig, a rare condition causing neurological signs. The embolism, originating from cartilage, obstructed brain vessels leading to necrotizing encephalopathy.
Area of Science:
- Veterinary Neurology
- Pathology
Background:
- Cerebral fibrocartilaginous embolism is a rare condition characterized by the obstruction of cerebral vessels by fibrocartilaginous material.
- While reported in humans and occasionally in other animal species, it has not been previously documented in pigs.
Observation:
- A 1-year-old boar presented with acute collapse and obtundation.
- Post-mortem examination revealed no significant gross lesions.
- Histopathology showed severe necrotizing encephalopathy with amorphous material obstructing brain vessels.
Findings:
- Alcian blue staining identified the obstructing material as cartilaginous in origin.
- A diagnosis of cerebral fibrocartilaginous embolism was made.
- The precise origin of the embolic material, such as vertebral disc disease, could not be determined.
Implications:
- This case represents the first documented instance of cerebral fibrocartilaginous embolism in a pig.
- Highlights the importance of histopathological examination for diagnosing rare neurological conditions in swine.
- Contributes to the understanding of fibrocartilaginous embolism in veterinary neurology.
