Abstract

A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is unique in that there was a latent period between infusion and development of PRES. We postulate that rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We suggest that neurological symptoms after blood transfusion should be appropriately investigated.
