Twenty patients were studied who developed central poststroke pain or paresthesia after lenticulocapsular hemorrhage. Pain or paresthesia occurred 0 to 24 months after the onset, more prominently in the leg than other body parts. The symptoms were described as numb, cold, burning, aching, swollen, and squeezing in various combinations. The mean score of the visual numerical scale was 5.6. The lesions involved the dorsal part of the posterior limb of the internal capsule, probably damaging the thalamocortical sensory pathway.
