Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
