Putaminal hemorrhage presenting pure sensory stroke is rare.We describe a case of left putaminal hemorrhage presenting contral ateral hemisensory disturbance without hemiparesis. A 52-year-old man developed analgesia and thermoanesthesi a in the right half of his body, but deep sensation was relatively well preserve d. Neuroradiological and somatosensory evoked potential findings suggested that thalamocortical sensory pathways to the secondary somatosensory cortex (S2)were involved, whereas those to the primary somatosensory cortex(S1) were spared. In experimental animals, spinothalamic projections from the thalamic nucleus input directly to S2. In humans, thalamocortical pathways are still a subject of debat e,but results of recent functional imaging studies suggest that the pathway of p ain inputs directly to S2 and that of tactile sensation to S2 via S1. Our findin gs support these reports. 展开更多
