Posttraumatic spinal cord herniation

We report a 28-year-old woman who presented with a partial Brown-Sequard syndrome 18 months after a fall from a horse. Investigation revealed the cause of her symptoms to be a spinal cord herniation at the level of T6. A review of previously reported cases of posttraumatic spinal cord herniation was undertaken. Six of the cases reported have clear evidence of injury at the site of subsequent herniation; the remaining five cases may be related to trauma or may be spontaneous spinal cord herniation, with an unrelated history of trauma.
