- In this study, the uninjured periventricular area of a female patient who presented with complete paralysis of the left extremities following middle cerebral artery infarction was analyzed using diffusion tensor tractography, transcranial magnetic stimulation, and functional magnetic resonance imaging. Diffusion tensor tractography revealed interrupted corticospinal tract at the infarct lesion in the corona radiata at 2 weeks after onset, which descended through the spared periventricular area at 6 months after onset. Transcranial magnetic stimulation and functional magnetic resonance imaging revealed a motor pathway of the affected hand that was compatible with the lateral corticospinal tract. At 6 months after onset, motor function in the affected extremities recovered to normal levels, which suggested that motor function in the affected hand recovered by the corticospinal tract that passed through the spared periventricular area. The arterial territory of the spared periventricular area corresponded with the anterior choroidal artery. These results suggest that care should be taken in spared periventricular areas in patients with lesions at the corona radiata level.
