Background And Purpose: Fibrocartilaginous embolism is a rare cause of ischemic myelopathy. Authors report a case of a 39-year-old woman with progressive tetraparesis and severe autonomic dysfunction. Despite of the detailed examinations, the definite diagnosis was verified by autopsy.
Methods: The patient was admitted because of progressive pain and numbness of the upper extremities and tetraparesis. Hypotonic muscles of the lower extremities with mild tetraparesis were observed. Magnetic resonance imaging showed an intramedullary lesion at the level of the cervical V-VII vertebral. Patient's tetraparesis worsened gradually to plegia with urinary retention. Expansive, rapidly progressing multiple decubiti developed, which were resistant to therapy. In spite of the complex therapy, the patient died.
Results: No internal disease was found to explain the death by autopsy. Multiple subacute infarctions of the cervical myelon (involving the lateral columns as well) in the territory of the anterior spinal artery were verified by neuropathological examination. The occluded vessels were filled by a material containing cartilaginous cells, while signs of atherosclerosis or thrombosis were not present.
Conclusion: Cartilaginous embolism of spinal arteries was diagnosed.

Background: Clinical characteristics of cervical hydrated nucleus pulposus extrusion (HNPE) in dogs compared to other causes of cervical myelopathy are not well described.
Hypothesis/objectives: To evaluate for clinical characteristics and mechanical ventilation likelihood associated with HNPE compared to other causes of cervical myelopathy.
Animals: Three hundred seventy-seven client-owned dogs from 2010 to 2022.
Anterior spinal artery syndrome (ASAS) is a rare form of spinal cord infarction, making its incidence and prevalence difficult to determine. We present the case of a 60-year-old woman with multiple vascular risk factors who experienced a sudden onset of severe lower limb weakness, raising immediate concerns about spinal cord ischemia. Diagnostic evaluations confirmed ASAS, although the exact cause and mechanism of her spinal cord infarction remained undetermined.

We describe the case of a male heavy machinery operator who presented from work with a rapidly evolving spinal cord syndrome. Spinal MRI revealed thoracic vertebral body and cord infarction and evolving mild disc prolapse attributed to fibrocartilaginous disc embolism (FCDE). FCDE should be considered as one of the aetiological mechanisms of acute spinal cord infarction in pile-driver/heavy machinery operators, especially in association with adjacent vertebral body infarction and intervertebral disc prolapse.

Background: Fibrocartilaginous embolic myelopathy (FCEM) and acute non-compressive nucleus pulposus extrusion (ANNPE) are common causes of acute spinal cord injury in dogs. Outcome among paraplegic deep pain positive (DPP) and deep pain negative (DPN) dogs with either condition and factors influencing recovery have not been clearly established.
Methods: Dogs with thoracolumbar FCEM or ANNPE resulting in paraplegia presenting to university hospitals between 2012 and 2022 were retrospectively included.

Introduction: Fibrocartilaginous embolism (FCE) is a rare spinal cord infarction due to embolism of fibrocartilaginous material with consecutive arterial infarction of the anterior spinal artery. Physical activity with increased axial pressure is the underlying mechanism of the retrograde migration of primarily nucleus pulposus material into the arterial system of the spinal cord. The initial severity of the clinical symptoms is supposed to be a prognostic predictor of recovery and so far, no specific treatment recommendation exists.
