Brown-Sequard Syndrome

Brown-Sequard syndrome results from a hemisection of the spinal cord. This is most commonly seen with low-speed penetration wounds, such as a stabbing. Corticospinal tracts and the dorsal columns cross in the brainstem, so their damage in this type of lesion leads to ipsilateral weakness and loss of vibration and position sense. The lateral spinothalamic tracts cross soon after entering the spinal cord, thus causing con­tralateral loss of pain and temperature sensation.
