Abstract
- Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache with reversible vasoconstriction of the cerebral arteries. RCVS has been reported to occur in various clinical settings. However, RCVS triggered by blood transfusion is rare. A 50-year-old woman had severe anemia and received multiple blood transfusions. She developed thunderclap headache after transfusion. Cerebral artery vasoconstrictions were demonstrated by magnetic resonance angiography and transfemoral cerebral angiography. RCVS might be triggered by red blood cell transfusion in patients with severe anemia.
