Reversible Cerebral Vasoconstriction Syndrome: A Commonly Missed Diagnosis in Acute Severe Headaches

Abstract

Summary: In spite of the recent acceptance to be a common cause of acute severe headaches, reversible cerebral vasoconstriction syndrome (RCVS) is still commonly missed. The syndrome is characterized by acute severe headaches due to the vasoconstriction of the cerebral arteries, which eventually resolve spontaneously. We present a reported case of RCVS with a typical magnetic resonance angiography (MRA) appearance and a review of the literature.
