Mineralizing lenticulostriate vasculopathy (mLSV), a recently been recognized as a risk factor for basal ganglia stroke in children after minor head trauma. Diagnosis may be missed if head CT is not performed, or findings of basal ganglia calcification disregarded. Cohort of children with basal ganglia stroke in whom the diagnosis of mineralizing lenticulostriate vasculopathy was assigned retrospectively. Sixteen children included 11 boys and 5 girls, aged from 20 months to 15 years who had had basal ganglia stroke in the past, met the inclusion criteria. None had previously received the diagnosis of mLSV. Twelve children presented with persistent hemiparesis after an acute stroke, 3 with seizures and 1 with migraine. Age of stroke onset, available in 15 children, ranged from 6 months to 48 months (mean 15.1 months). Interval between the stroke onset (n=15) and diagnosis of mineralizing lenticulostriate vasculopathy was 8 months to 168 months (mean 46.3 months) being 2 years to 10 years in 9 and > 10 years in 2 children. History of minor head trauma preceding the basal ganglia stroke was noted in 10 (62.5%) cases. Two children who presented with seizures had had complete motor recovery from stroke. Silent, asymptomatic basal ganglia strokes without any motor deficits were observed in 2 children. In 6 children, already available CT images and in 10 children head CT performed in our hospital confirmed the diagnosis of mineralizing lenticulostriate vasculopathy. Retrospective diagnosis of mineralizing lenticulostriate vasculopathy is possible and has implications for treatment and prognosis.
