Posterior reversible encephalopathy syndrome (PRES) is characterized by the
following symptoms: seizures, impaired consciousness and/or vision,
vomiting, nausea, and focal neurological signs. Diagnostic imaging includes
examination by magnetic resonance (MR) and computed tomography (CT), where
brain edema is visualized bi-laterally and symmetrically, predominantly
posteriorly, parietally, and occipitally. Case report. We presented a
73-year-old patient with the years-long medical history of hipertension and
renal insufficiency, who developed PRES with the symptomatology of the rear
cranium. CT and MR verified changes in the white matter involving all lobes
on both sides of the brain. After a two-week treatment (antihypertensive,
hypolipemic and rehydration therapy) clinical improvement with no
complications occurred, with complete resolution of changes in the white
matter observed on CT and MR. Conclusion. PRES is a reversible syndrome in
which the symptoms withdraw after several days to several weeks if early
diagnosis is made and appropriate treatment started without delay.
