Author: Eric Miller, MD Educational Pearls: Brown-Sequard Syndrome is a neurological deficit that results from hemisection of the spinal cord  This is usually from traumatic injury (blunt or penetrating), but can rarely be seen with cancer, disc herniation, or infection It presents with flaccid paralysis and loss of sensation to touch/vibration/position on the same side as the injury with loss of pain/temperature sensation on the opposite side of the injury.  These deficits will be below the level of injury.    References Roth, E., Park, T., Pang, T. et al.
