Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is a rare condition in which parts of the brain are affected by swelling, usually as a result of an underlying cause.
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]
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]
Posterior reversible encephalopathy syndrome (PRES) can also result from medication toxicity. [4] [8] [12] Symptoms similar to those of leukoencephalopathy patients have been seen in PRES patients. However, the prognosis of toxic leukoencephalopathy is typically slightly worse than that of PRES because toxic leukoencephalopathy is more likely ...
Hypertensive encephalopathy (HE) is general brain dysfunction due to significantly high blood pressure. [3] Symptoms may include headache, vomiting, trouble with balance, and confusion. [1] Onset is generally sudden. [1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye. [1] [3]

Generalized brain swelling can occur in ischemic-anoxia states, acute liver failure, [9] hypertensive encephalopathy, hypercarbia (hypercapnia), and Reye hepatocerebral syndrome. These conditions tend to decrease the cerebral perfusion pressure but with minimal tissue shifts.
