Abstract:
Congenital hemiplegia is a subtype of the cerebral palsies characterized by a predominantly spastic movement affecting on side of the body only. It is caused by brain lesions acquired during the prenatal, perinatal, or neonatal periods. It is generally assumed that the damage to the corticospinal tract accounts for most motor deficits in cerebral palsy patients. Ipsilateral motor evoked potentials are likely to be indicative of a profound functional reorganization of corticospinal projections originating from the undamaged hemisphere. The existence of the ipsilateral motor pathway from the unaffected hemisphere has been reported in hemiplegic cerebral palsy using the transcranial magnetic stimulation technique. Here, we report the case of a hemiparetic patient with severe unilateral brain atrophy including brain stem. Transcranial magnetic stimulation to the hypertrophic hemisphere elicited bilateral motor evoked potentials of the first dorsal interossei and ipsilateral responses were shorter onset latencies, implying direct ipsilateral corticospinal projections from the unaffected hemisphere.
