A 10-year-old German shepherd dog was presented with peracute onset of non-ambulatory paraparesis. Clinical signs and neurological examination revealed lack of proprioception and reduced to absent reflexes in both hind limbs, indicating a lesion to spinal cord segments (SCS) L4–S3. In contrast, MRI identified intramedullary signal changes within the SCS T13–L2 and a sharply demarcated zone of signal changes in the adjacent dorsal lumbar musculature on the left side. The findings were consistent with ischaemic myelopathy, most likely due to fibrocartilaginous embolism (FCE). The lesion also included large areas of presumably ischaemic myopathy which was confirmed by histopathology of biopsies from adjacent muscles. On re-examination, three months after presentation, ambulatory paraparesis remained, proprioceptive deficits improved and spinal reflexes were normal. However, the affected left longissimus lumborum muscle had become markedly atrophic. FCE as the most common cause for ischaemic myelopathy obviously may also induce ischaemic paraspinal myopathy.
