Ipsilateral Hemiparesis Caused by Supratentorial Stroke: Two casereports

A common symptom that occurs after strokes is impaired contralesional motor function and contralateral limbs weakness. Such weakness of the limbs is often found in a supratentorial stroke. Two patients with ipsilateral limbs weakness after supratentorial stroke events were reported. One was a recurrent ischemic stroke in the right frontal lobe with right hemiparesis; the other was a new ischemic stroke in the right thalamus with right hemiparesis. There were few reported cases of ipsilateral hemiparesis caused by a supratentorial cerebral lesion. The mechanism of such symptoms may be related to 1. Activation and cortical reorganization within the motor areas of the unaffected hemisphere; and 2. Uncrossed pyramidal tract. In this report, we present clinical evidences and image data, as well as a reviewarticle of associated literatures.
