Background In the 1840s Brown-Séquard described the motor and sensory effects
of sectioning half of the spinal cord. Penetrating injuries can cause Brown-Séquard
or, more frequently, Brown-Séquard–plus syndromes.
Objective To report the case of a 25-year-old man who developed left-sided Brown-Séquard
syndrome at the C8 level and left-sided Horner syndrome plus urinary retention
and bilateral extensor responses following a stab wound in the right side
of the neck.
Results Magnetic resonance imaging demonstrated a low cervical lesion and somatosensory
evoked potentials confirmed the clinical finding of left-side dorsal column
disturbance. At follow-up, the patient's mobility and bladder function had
returned to normal.
Conclusion This patient recovered well after a penetrating neck injury that disturbed
function in more than half the lower cervical spinal cord (Brown-Séquard–plus
syndrome).
