Blood transfusion-related posterior reversible encephalopathy syndrome

Abstract

Neurological complications have rarely been described after blood transfusion. Posterior reversible encephalopathy syndrome (PRES) is a recently recognized entity affecting predominantly the posterior cerebral hemispheres. We report two distinctive cases with history of chronic anemia that developed headache, blurred vision and seizure after blood transfusion. Magnetic resonance imaging indicated vasogenic edema consistent with PRES.
