OBJECTIVE Symptoms of posterior reversible encephalopathy syndrome (PRES) include headache, altered mental status, visual disturbances, and seizures. Typical radiological features include edema of the parieto-occipital lobes. The purpose of this study is to review the clinical and radiological findings in patients diagnosed with PRES. METHODS All patients diagnosed with PRES between January 2...

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological syndrome characterized by various symptoms of neurological disease. It has commonly been reported in association with acute hypertension, pre-eclampsia, eclampsia, sepsis, and exposure to immunosuppressants. Here, we report on a normotensive woman who developed a severe frontal headache, visual disturbances, and ...

OBJECTIVE Analyze the cases of posterior reversible encephalopathy syndrome (PRES) admitted in a Neurology Department during an 8-year period. METHOD Retrospective observational study in a central hospital in the north of Portugal. RESULTS 14 patients were identified, mean age 52.3 years. Precipitating factors included: eclampsia, isolated arterial hypertension, spinal trauma and autonomic ...

Posterior reversible encephalopathy syndrome (PRES) or reversible posterior leukoencephalopathy (RPL) is an acute neurological syndrome characterized by the development of radiological abnormalities on brain imaging along with clinical manifestations, such as a headache, seizures, encephalopathy, etc. We report the case of a middle-aged male who presented to the emergency department after he wo...

A. Pirker L. Kramer B. Voller B. Loader E. Auff D. Prayer SUMMARY: PRES is a clinicoradiologic entity, combining seizures, blindness, and coma with MR imaging findings of predominantly vasogenic and occasional cytotoxic edema. In this clinical report, we determined the type of edema by using DWI and FLAIR sequences on MR imaging as well as ADC maps in 28 patients with PRES. The neuradiologic fi...

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by headache, confusion, seizures, and cortical visual loss, as well as subcortical edema without infarction on neuroimaging. We report a 56-year-old woman who developed typical manifestations of PRES, 6 days after blood transfusion for severe anemia. Acute volume overloads by transfusion may exce...

Posterior reversible encephalopathy syndrome (PRES) is characterized by a clinical and radiological entity with the sudden onset of seizures, headache, altered consciousness, and visual disturbances in patients with the findings of reversible vasogenic subcortical edema without infarction. Hypertension, renal disease, and autoimmune disease are co-morbid conditions of PRES. Nevertheless, there ...

Posterior reversible encephalopathy syndrome (PRES) is characterized by neuroimaging findings of symmetric changes of vasogenic edema predominantly in the posterior subcortical regions of the brain. The cause of PRES remains unclear. We describe a 66-year-old female patient who developed PRES with normal blood pressure on the first day after being attacked by a swarm of wasps. Over the next few...

As a hepatitis B virus (HBV) envelope domain, preS plays significant roles in receptor recognition and viral infection. However, the regions critical for maintaining a stable and functional conformation of preS are still unclear and require further investigation. In order to unravel these regions, serially truncated fragments of preS were constructed and expressed in Escherichia coli. Their sol...

Background: Posterior reversible encephalopathy syndrome (PRES) is a reversible syndrome characterized by seizures, headache, altered mentation, and loss of vision associated with white matter changes on imaging. Case: A 37-year-old multigravida woman had a severe, immediate postpartum eclampsia-HELLP syndrome (hemolysis, elevated liver enzyme levels, low platelet count) with PRES characterized...
