Ipsilateral seizures

Seven patients who had partial elementary seizures on the same side as the cerebral lesion are described. In six patients the seizures were partial motor, and one patient had seizures which ware partial elementary with sensory symptomatology. Four patients had frontal lesions, two parietal, and one parietotemporal. Five patients out of seven had lesions in the right cerebral hemisphere. There were three cases with astrocytoma, two with infarction, and one each with meningioma and tuberculoma. The clinical significance and pathophysiological mechanisms of this rare ipsilateral sign are discussed.
