Abstract

A 63-year-old man was admitted with newly developed left hemiparesis. He had experienced left hemiparesis that had resulted from an earlier right thalamic hemorrhage. Diffusion-weighted images showed only high signal intensity lesion in the left internal capsule. Ipsilateral motor evoked potentials were obtained at the affected hand muscles when the unaffected motor cortex was stimulated. This suggests that cortical reorganization in the unaffected hemisphere after the first stroke may be involved in the occurrence of such symptom.
