Clinical spectrum and critical care management of Posterior Reversible Encephalopathy Syndrome (PRES)

Posterior Reversible Encephalopathy (PRES) is characterized by acute-onset headache, altered mental status, cortical blindness and seizures, with parietal-occipital involvement. We report all cases of PRES diagnosed in our intensive care unit during the last 4 years, and evaluate their outcome in terms of the different medical treatments used. Even if usually reversible, PRES can sometimes result in death or irreversible neurological deficit, such as chronic epilepsy.
