A diagnosis of fibrocartilaginous embolism was made in a mature mixed-breed sow with a history of an acute onset of pelvic limb paralysis. Within a single section of lumbar spinal cord, there was severe focally-extensive infarction of the right ventral gray horn. Within affected white matter, there was dilatation of multiple myelin sheaths with concurrent axonal swelling. A smaller focus of infarction was present on the contralateral side. Arteries at the periphery of both lesions contained a blue-gray material with staining characteristics similar to that evidenced by the nucleus pulposus present within intervertebral discs. Grossly, no abnormalities were present within the vertebral column.
对一头有后肢急性麻痹病史的成年杂交母猪进行了纤维软骨栓塞的诊断。在腰脊髓的单个切片中，右侧腹侧灰质角有严重的局灶性广泛梗死。在受影响的白质内，多个髓鞘扩张并伴有轴突肿胀。对侧有一个较小的梗死灶。两个病变周边的动脉含有一种蓝灰色物质，其染色特征与椎间盘内的髓核相似。大体上，脊柱内未发现异常。
