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]

In many cases there is evidence of constriction of the blood vessels (if angiography is performed), suggesting a possible overlap with reversible cerebral vasoconstriction syndrome (RCVS). Diffusion MRI may be used to identify areas of cytotoxic edema caused by poor blood flow (ischemia) but it is not clear if this prognostically relevant.
Reversible cerebral vasoconstriction syndrome (previously Call-Fleming syndrome, several subtypes) Primary cough headache, primary exertional headache, and primary sexual headache; The most important of the secondary causes are subarachnoid hemorrhage, cerebral venous sinus thrombosis, and dissection of an artery in the neck.

High resolution MRI may show hyperenhancement of the blood vessel walls in primary CNS vasculitis and may help to distinguish the lesions form atherosclerotic plaques or reversible cerebral vasoconstriction syndrome which have similar morphology on angiography. MRI usually also shows multiple infarcts, enhancement of the leptomeninges (the ...

Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death . Along with physical resistance, vasospasm is a main cause of ischemia. Like physical resistance, vasospasms can occur due to atherosclerosis.
