Posterior reversible encephalopathy syndrome; Other names: Reversible posterior leukoencephalopathy syndrome (RPLS) Posterior reversible encephalopathy syndrome visible on magnetic resonance imaging as multiple cortico-subcortical areas of T2-weighted hyperintense (white) signal involving the occipital and parietal lobes bilaterally and pons.
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]
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 is present in a small minority of patients. [ 2 ] [ 3 ] [ 4 ] This condition features the unique property that the patient's cerebral arteries can spontaneously constrict and relax back and forth over a period of time without intervention and without clinical findings.
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 ...
Ifosfamide can cause a severe encephalopathy (but it can be reversible with stopping use of the drug and starting the use of methylene blue). [5] Bevacizumab and other anti–vascular endothelial growth factor medication can cause posterior reversible encephalopathy syndrome. [5]

The most prominent symptoms are "clumsiness, progressive weakness, and visual, speech, and sometimes personality changes". [1] The lesions affecting the parietal and occipital lobes of the brain can lead to a phenomenon known as alien hand syndrome. [2]
