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.

一头 1 岁公猪在出现急性发作性倒塌和迟钝后接受了调查。尸检时未观察到明显的肉眼损伤。组织病理学检查显示严重的双侧多灶性坏死性脑病，伴有无定形物质，阻塞了后脑和中脑的神经实质血管。阿尔辛蓝染色鉴定出该物质为软骨来源，并确立了脑纤维软骨栓塞的诊断。没有检测到椎间盘疾病的明显证据，也没有发现栓塞物质的来源。虽然脑纤维软骨栓塞在人类中已有报道，但在动物中很少见，但以前在猪中没有报道过。
