Question

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

Explanation:

• Hemicord lesion (Brown-Séquard syndrome) causes ipsilateral motor loss and contralateral loss of pain/temperature below the lesion, as spinothalamic tract fibers cross shortly after entering the cord.
• Anterior cord syndrome leads to bilateral loss of pain/temperature and motor function, sparing posterior column sensations.
• Posterior cord syndrome affects proprioception, vibration, and touch, not pain/temperature.
• Transverse cord lesion causes bilateral loss of all sensory and motor functions below the lesion.

Answer:

Hemicord lesion
