What is the most common cause of Brown-Séquard syndrome?

The most common causes of Brown-Séquard syndrome (BSS) are traumatic injuries affecting your spinal cord, including:

  • Gunshot wounds.
  • Stab wounds.
  • Motor vehicle accidents.
  • Blunt trauma.
  • Spinal fractures from an accident such as a fall.

If you experience any of these traumatic injuries, it’s important to get to the nearest hospital as soon as possible and receive immediate medical care.

There are several other less common causes of BSS that are due to non-traumatic conditions, including:

  • Cervical (neck) spondylosis.
  • Decompression sickness.
  • Herniated disk.
  • Meningitis.
  • Multiple sclerosis (MS).
  • Radiation exposure.
  • Spinal ischemia (obstruction of a blood vessel).
  • Spinal tumors.
  • Transverse myelitis.
  • Tuberculosis.
