Posterior reversible encephalopathy syndrome in preeclampsia and eclampsia: The role of hypomagnesemia

Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is a special type of cerebrovascular disease defined by its clinical and imaging manifestations [1]. The onset of PRES typically occurs acutely or subacutely and involves a variety of nonspecific symptoms, including headaches, visual changes, seizures, consciousness impairment, mental disorders, focal neurologic deficits, nausea, and vomiting [2,3]. MRI is the gold standard for the diagnosis and evaluation of PRES [4], and the imaging features of this condition include vasogenic edema in the subcortical white matter in the majority of patients and possible cytotoxic edema in some patients [5].
