Ipsilateral hemiplegia caused by right internal capsule and thalamic hemorrhage: Demonstration of predominant ipsilateral innervation of motor and sensory systems by MRI, MEP, and SEP

A patient with a right internal capsule and thalamic hemorrhage showed ipsilateral hemiplegia. MRI at 10 months after the cerebral hemorrhage demonstrated Wallerian degeneration, which could be traced to the ipsilateral anterior funiculus at the cervical level. The findings of motor evoked potentials and somatosensory evoked potentials indicate a predominantly ipsilateral innervation of motor and sensory systems in this particular patient.
