Posterior reversible encephalopathy syndrome (PRES) is characterized by acute onset of headache, nausea, focal neurological deficits or seizures along with radiological findings of white matter defects in the parietal and occipital lobes. Causes of PRES include uremia, hypertensive encephalopathy, eclampsia and immunosuppressive medications. Usually, the treatment of choice involves correcting ...

Neurological findings in preeclampsia fulfill diagnostic criteria of posterior reversible encephalopathy syndrome (PRES), which is related to cerebral autoregulation impairment associated with high blood pressure. In preeclampsia, PRES may occur without a significant increase in blood pressure. Our aim was to investigate the association between ophthalmic artery resistive index (OARI) and clini...

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity characterized by headaches, altered mental status, seizures, and visual disturbances. It can occur in many different clinical entities such as severe hypertension and pre-eclampsia, or due to cytotoxic or immunosuppressive therapies. The pathogenesis of PRES is unclear, with dysregulated cerebral auto-regulation a...

A diagnosis of posterior reversible encephalopathy syndrome (PRES) is based on a combination of clinical symptoms including headache, altered alertness, abnormalities of visual perception, and seizure, and characteristic neuroimaging findings of transient white matter edema, mostly in the posterior parietal-temporaloccipital regions of the brain (1, 2). Conditions commonly associated with PRES ...

Posterior reversible encephalopathy syndrome (PRES) is a rare occurrence in patients with Guillain-Barré syndrome (GBS). Two patients with neuroradiological evidence of PRES without central nervous system (CNS) symptoms were recently reported. We present the case of a GBS patient with minimal CNS symptoms and magnetic resonance imaging findings consistent with PRES. PRES in GBS might be an unde...

PURPOSE This study was intended to describe the risk of epilepsy subsequent to posterior reversible encephalopathy syndrome (PRES) and the clinical features of post-PRES epilepsy. METHOD We retrospectively identified all patients with PRES who were admitted to Severance Hospital and consulted with the Department of Neurology between 2001 and 2013 and the subgroup of these patients who subsequ...

BACKGROUND AND PURPOSE Posterior reversible encephalopathy syndrome (PRES) is known to occur after solid organ transplantation (SOT), potentially associated with cyclosporine and tacrolimus. In this study, we assess the frequency and clinical and imaging characteristics of PRES after SOT. MATERIALS AND METHODS We identified 27 patients (13 men and 14 women; age range, 22-72 years) who develop...

In accelerated hypertension, vasogenic brain edema associated with PRES may represent either autoregulatory breakthrough leading to vasodilation or excessive autoregulation leading to vasoconstriction. We describe 2 patients with PRES in accelerated hypertension who had serous retinal detachments, a vasoconstrictive phenomenon. The concurrence of serous retinal detachment and PRES offers intrig...

Posterior reversible encephalopathy syndrome (PRES) is characterized by variable associations of seizure activity, consciousness impairment, headaches, visual abnormalities, nausea/vomiting, and focal neurological signs. The PRES may occur in diverse situations. The findings on neuroimaging in PRES are often symmetric and predominate edema in the white matter of the brain areas perfused by the ...

The posterior reversible encephalopathy syndrome (PRES) is a novel entity clinically manifested by headache, changes of sensorium, seizures, and visual loss. PRES pathogenesis has not been fully clarified. The entity can be associated to a variety of clinical conditions, mainly hypertension, renal insufficiency and immunosuppressive therapy. A possible link of autoimmune disorders with PRES has...
