A 1-year-old boar was investigated after presenting with acute onset collapse and obtundance. No significant gross lesions were observed at post-mortem examination. Histopathological investigation revealed a severe bilateral and multifocal necrotizing encephalopathy with an amorphous material, which obstructed neuroparenchymal vessels in the metencephalon and mesencephalon. Alcian blue staining identified the material as of cartilaginous origin and a diagnosis of cerebral fibrocartilaginous embolism was established. No gross evidence of vertebral disc disease was detected and the origin of the embolic material was not found. Although cerebral fibrocartilaginous embolism has been reported in a human, and rarely in animals, it has not been reported previously in the pig.
