Fibrocartilaginous embolic myelopathy in a horse.

The research article is about an 11-year-old horse diagnosed with fibrocartilaginous embolic myelopathy, a typically rare and severe spinal cord condition, confirmed via post-mortem examination of the spinal cord.

Horse Selection and Condition

• The subject of the study was a male Tennessee Walking Horse of 11 years.
• The horse had developed severe neurological dysfunctions which led to its killing for the scientific study.

Fibrocartilaginous Embolic Myelopathy Diagnosis

• Upon death, a histopathological examination of the horse’s spinal cord was conducted to understand the underlying cause of the neurological dysfunction it suffered from.
• The diagnosis revealed a condition known as fibrocartilaginous embolic myelopathy.
• This disorder is not common and is typically severe, impacting the spinal cord of the affected animal.

Anatomical Findings

• Key findings from the preliminary examination of the horse’s cervical spinal cord (specifically C6 and C7) showed widespread necrosis or tissue death.
• The primary cause for this necrosis were fibrocartilaginous emboli – fragments of fibrocartilage that got lodged in the blood vessels and triggered a blockage of blood flow.
• Such a fibrocartilaginous embolus was also spotted within a single large spinal artery adjacent to the vertebral leptomeninges, further affirming the diagnosis.

Implication

• The study suggests the relevance of post-mortem examinations for confirming certain intricate and rare disorders like the fibrocartilaginous embolic myelopathy.
• It also sheds light on the potential causes and manifestations of severe neurological dysfunction in horses.
