Question

which spinal cord lesion is most consistent with contralateral loss of pain and temperature sensation? transverse cord lesion posterior cord syndrome anterior cord syndrome hemicord lesion

Explanation:

• Transverse cord lesion causes bilateral loss of all sensations.
• Posterior cord syndrome affects proprioception and vibration, not pain/temperature.
• Anterior cord syndrome causes bilateral loss of pain/temperature.
• Hemicord lesion (Brown-Séquard syndrome) results in contralateral loss of pain and temperature sensation (from spinothalamic tract damage) alongside ipsilateral motor and proprioceptive loss.

Answer:

D. Hemicord lesion
