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.
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 ...
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.

The treatment of cerebral edema depends on the cause and includes monitoring of the person's airway and intracranial pressure, proper positioning, controlled hyperventilation, medications, fluid management, steroids. [3] [7] [8] Extensive cerebral edema can also be treated surgically with a decompressive craniectomy. [7]
The pathophysiology of cranial venous outflow obstruction involves the disruption of normal venous drainage from the brain. Cerebral veins play a crucial role in draining brain interstitial fluid (ISF), and their significance has been linked in various neurological conditions. [1] It can be caused by extrinsic or intrinsic anomalies. [7]
Cerebral vasospasm is the prolonged, intense vasoconstriction of the larger conducting arteries in the subarachnoid space which is initially surrounded by a clot.Significant narrowing of the blood vessels in the brain develops gradually over the first few days after the aneurysmal rupture.
