Recurrent Thunderclap Headaches and Multilobar Intracerebral Haemorrhages: Two Cases of Reversible Cerebral Vasoconstriction Syndrome (RCVS)

Abstract

We describe two patients with thunderclap headaches due to reversible cerebral vasoconstriction syndrome (RCVS). The first patient illustrates multilobar intracerebral haemorrhages as an under-appreciated feature of RCVS, and the second illustrates recurrent thunderclap headache (presumed recurrent RCVS) after a long interval of 4 years. These cases demonstrate the spectrum of presentation of RCVS, a clinically under-recognized condition.
