[Infarct of the basal ganglia in childhood--clinico-neuroradiologic findings and differential diagnosis].

Basal ganglionic infarctions during childhood are comparable in size and favourable prognosis with lacunary infarctions in adults. Considering their etiology they are comparable with capsular infarctions in adults. In four children with basal ganglionic infarctions and acute motoric hemiparesis, a quick and complete regression of clinical signs and CT-findings was observed. With regard to the differential diagnosis of basal ganglionic infarction we additionally report of a female patient with initially unilateral lesion who had silently developed the hemiparesis. In this case the clinical course and the neuroradiological follow-up findings suggested Leigh disease.
