Posterior Reversible Encephalopathy Syndrome and Reversible Cerebral Vasoconstriction Syndrome after Rapid Blood Transfusion

We herein report a case of posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS) that occurred immediately after blood transfusion. A 64-year-old Japanese woman was diagnosed with liver cirrhosis due to hepatitis B 2 years ago. She was admitted to our hospital with hemorrhagic shock due to esophageal variceal rupture. She was hospitalized with rapid blood pumping transfusion, after which consciousness disorder appeared, and her blood pressure suddenly increased. Magnetic resonance imaging revealed PRES and RCVS. We speculated that hypoalbuminemia and blood transfusion might have been involved in the development of PRES and RCVS.
