Short-segment myelitis presenting as Brown-Séquard-plus syndrome as the initial attack of multiple sclerosis.

Brown-Séquard syndrome is an uncommon condition accounting incomplete spinal cord injury, manifesting as ipsilateral weakness and proprioception loss, associated with contralateral pain and temperature sensation loss. Brown-Séquard-plus syndrome (BSPS) has not quite a well-stablished definition, but usually is defined as a Brown-Séquard syndrome associated with clinical findings compatible with another spinal cord tract. We present a pearls & oysters article naming the most relevant findings and aspects to evaluate in this pathology, throughout a clinical case where a patient presents a Brown-Séquard-plus syndrome as the initial attack in multiple sclerosis.
