Lacunar infarction of the basal ganglia as a complication of hemolytic-uremic syndrome. MRI and clinical correlations.

Central nervous system (CNS) complications of hemolytic-uremic syndrome (HUS) commonly consist of alterations in mental status, seizures, and rarely hemiparesis. The authors report the clinical evolution of left hemiparesis and later choreo-athetoid movements in a patient who sustained a right lacunar infarction as a complication of HUS. The infarction is demonstrated on magnetic resonance imaging (MRI).
