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]

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 ...
Trousseau's syndrome is a rare variant of venous thrombosis that is characterized by recurrent, migratory thrombosis in superficial veins and in uncommon sites, such as the chest wall and arms. This syndrome is particularly associated with pancreatic, gastric and lung cancer and Trousseau's syndrome can be an early sign of cancer [ 2 ] [ 3 ...
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.
Posterior reversible encephalopathy syndrome (PRES) is a rare clinical disease characterized by cerebral edema. [12] The exact pathophysiology , or cause, of the syndrome is still debated but is hypothesized to be related to the disruption of the blood-brain barrier. [ 12 ]
The Mayo Clinic Cancer Center is one of the oldest NCI-designated cancer centers in the United States, having first been designated in 1973. [3] The main location of the Mayo Clinic is in Rochester, MN. Campuses in Arizona and Florida opened later and became part of the Mayo Clinic Cancer Center in 2003. [4] [5]
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.
