Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological entity presented with different symptoms such as visual disturbances, headaches, seizures, severe hypertension and altered mental status. It has been recognized in a different pathological conditions, although preeclampsia/eclampsia is the most common cause of PRES. The pathogenesis of PRES is still not fully understood, but it seems that failure of cerebrovascular autoregulation causing vasogenic edema, cerebral vasoconstriction, and disruption of the blood brain barrier plays an important role. Cortical blindness, hypertensive retinopathy, serous retinal detachment (SRD), central retinal artery and vein occlusions, retinal or vitreous hemorrhages, anterior ischemic optic neuropathy (AION) and Purtscher’s retinopathy are ophthalmic disorders that may occur in PRES associated with preeclampsia. Among these, cortical blindness is the best documented complication of preeclampsia. Magnet resonance imaging (MRI) is a gold standard to establish the diagnosis of PRES because clinical findings are not sufficiently specific. Typically, there are bilateral cortical occipital lesions with hyperdensity on T2-weighted MRI. Blindness due to occipital lesions is reversible and the vision loss is usually regained within 4 h to 8 days.

Posterior reversible encephalopathy syndrome (PRES) is a rare and poorly understood neurologic condition that has been described in some patients with systemic lupus erythematosus (SLE). Intracerebral hemorrhage is a unique and atypical presentation of PRES and has been described only in a small number of patients with SLE. We present the case of a 33-year-old female, diagnosed with SLE and active nephritis, who was admitted for seizures. She had acute-onset headache, confusion, and bilateral vision loss associated with severe hypertension. CT scan revealed right occipital and parietal lobe hemorrhage. MRI showed vasogenic edema and hyperintense foci in bilateral cortical and subcortical regions of the occipital and posterior parietal lobes which are consistent with posterior reversible encephalopathy syndrome (PRES). Strict blood pressure control and medical ICP-lowering treatment were immediately instituted, while maintaining her on anticonvulsants, high-dose steroids, and mycophenolate mofetil. The patient was discharged with improvement in vision and resolution of headache. On follow-up, she had gained her premorbid visual acuity and reported no recurrence of headache or seizures. Despite its name, reversibility remains to be conditional in PRES. A high index of suspicion is important, especially among those who present with seizure, headache, and visual loss. Early diagnosis and timely initiation of therapy is recommended, as clinical symptoms are potentially reversible and delayed therapy may result in life-threatening complications, such as coma or death.

Posterior Reversible Encephalopathy Syndrome (PRES) is a very rare cause of sudden onset vision loss in pregnancy. There are only few case reports in literature. It is characterized by headache, seizures, altered mental status and visual deficits ranging from visual neglect to cortical blindness. Here a case if PRES has been reported with discussion on its pathophysiology. NJOG 2011 Nov-Dec; 6 (2): 51-52 DOI: http://dx.doi.org/10.3126/njog.v6i2.6759

Abstract Background Leptospirosis is a zoonotic spirochetal disease caused by Leptospira interrogans. The clinical presentation ranges from an asymptomatic state to a fatal multiorgan dysfunction. Neurological manifestations including aseptic meningitis, spinal cord and peripheral nerve involvement, cranial neuropathies and cerebellar syndrome are well recognized with varying frequencies among patients with this disease. Posterior reversible encephalopathy syndrome is a very rare occurrence in leptospirosis and only two cases are reported in the medical literature up to now. We report a case of posterior reversible encephalopathy syndrome in a patient with leptospirosis with rhabdomyolysis and acute kidney injury. Case presentation A 21 year-old male presented with fever and oliguric acute kidney injury with rhabdomyolysis. A diagnosis of leptospirosis was made and he was being managed according to the standard practice together with regular hemodialysis. The clinical condition was improving gradually. On day 8 of the illness, he developed headache and sudden painless complete bilateral vision loss followed by several brief generalized tonic clonic seizure attacks. Examination was significant for a Glasgow Coma Scale of 14/15, blood pressure of 150/90 mmHg and complete bilateral blindness. The findings of magnetic resonance imaging of the brain were compatible with posterior reversible encephalopathy syndrome. He was managed with blood pressure control and antiepileptics with supportive measures and standard treatment for leptospirosis and made a complete recovery. Conclusion Posterior reversible encephalopathy syndrome, though very rare with leptospirosis, should be considered as a differential diagnosis in a patient with new onset visual symptoms and seizures, especially during the immune phase. Optimal supportive care together with careful blood pressure control and seizure management would yield a favourable outcome in this reversible entity.

Posterior reversible encephalopathy syndrome is a condition occurring  in majority of case of  hypertensive encephalopathy mainly due to vasogenic  edema in parieto occipital region in neuroimaging. It is reversible if timely treatment is done .Here we are reporting a 11 year old female child with acute post streptococal glomerulonephrtitis leading to typical clinical and radiological features of posterior reversible encephalopathy syndrome

Brain vasogenic edema, involving disruption of the blood-brain barrier, is a common pathological condition in several neurological diseases, with a heterogeneous prognosis. It is sometimes reversible, as in posterior reversible encephalopathy syndrome, but often irreversible and our current clinical tools are insufficient to reveal its reversibility. Here, we show that increased fractional anisotropy in magnetic resonance imaging is associated with the reversibility of vasogenic edema. Spontaneously, hypertensive rats-stroke prone demonstrated posterior reversible encephalopathy syndrome-like acute encephalopathy in response to high-dose cyclosporine A treatment; the deteriorating neurological symptoms and worsening scores in behavioral tests, which were seen in acute phase, dissappered after recovery by cessation of cyclosporine A. In the acute phase of encephalopathy, the fractional anisotropy and apparent diffusion coefficient increased in areas with IgG leakage. This increase of fractional anisotropy occurred in the absence of demyelination: fluid leakage into the myelinated space increased the axial, but not the radial, diffusivity, resulting in the increased fractional anisotropy. This increased fractional anisotropy returned to pre-encephalopathy values in the recovery phase. Our results highlight the importance of the fractional anisotropy increase as a marker for the reversibility of brain edema, which can delineate the brain areas for which recovery is possible.

We are reporting the case of a woman who was admitted acutely to our intensive care unit without any collateral history. She was diagnosed with posterior reversible encephalopathy syndrome (PRES) as a consequence of poor adherence to anti-hypertensive, anti-diabetic and anti-retroviral medications. PRES is a rare condition, which may cause cortical blindness; contrary to its name it is not always reversible. Rapid diagnosis and aggressive management of underlying causes facilitate reversibility of PRES. We also summarise the literature on patients with HIV and PRES.

Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic state, caused by imbalance in autoregulation of posterior cerebral circulation. We report a case of young female, presented at emergency department with complains of nausea, vomiting and generalized tonic clonic seizures prior to admission. During the course of hospital stay patient landed in status epilepticus which was treated appropriately. Patient’s magnetic resonance imaging (MRI) was done which had classical features of vasogenic edema in occipital and parietal region, suggestive of PRES. She was a known case of autoimmune hemolytic anemia thatwas treated with multiple blood transfusions and low dose oral steroids. She was discharged after complete resolution of symptoms with the advice to follow up in medicine outpatient department. Our case describes about autoimmune hemolytic anemia in which occurrence of PRES is uncommon. Early diagnosis and robust treatment can prevent permanent damage to the brain, and is often associated with complete recovery.

Posterior reversible encephalopathy syndrome (PRES) comprises a unique pattern of brain vasogenic edema that is seen in the setting of a neurotoxic status. Besides many etiologies have been already associated with PRES development, such as chronic renal disease, use of chemotherapy agents and inflammatory conditions, the imaging features are very suggestive and helpful for an appropriate diagnosis. We report here a case of PRES secondary to post-streptococcal glomerulonephritis (PSGN), which evolved successfully after clinical management. An 11-year-old boy was admitted with a typical history and findings of PSGN, associated with sensory alterations, headache and recent tonic-clonic seizure. Computed tomography (CT) scan of the head has revealed bilateral and symmetric hypodense areas, remarkably located at posterior cerebral regions, indicating PRES. Patient received support therapy with diuretics, and antibiotics prescription after discharge. At ambulatory follow-ups, the patient remains asymptomatic, with complete clinical and radiological improvement.Bangladesh Journal of Medical Science Vol. 12 No. 03 July ’13 Page 341-343 DOI: http://dx.doi.org/10.3329/bjms.v12i3.13323
