Blood transfusion-induced posterior reversible encephalopathy syndrome presenting severe brain atrophy: A report of two cases.

ABSTRACT

Several cases of posterior reversible encephalopathy syndrome (PRES) after blood transfusion have been reported, but the long-term prognosis is unknown. Here, we report two cases of blood transfusion-associated PRES with severe brain atrophy at 1 year after onset. We report the case with a discussion of pathological mechanisms.
