Reversible Encephalopathy

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.

Reversible Encephalopathy

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.

Reversible Encephalopathy

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.

Reversible Encephalopathy

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

Reversible Encephalopathy

Posterior reversible encephalopathy syndrome is a clinical–radiographic syndrome of progressive headaches, blurred vision, confusion, and seizures in the setting of vasogenic edema on brain imaging, which is often localized to the posterior white matter. The symptoms are classically triggered by severe hypertension, pregnancy and the puerperium, or exposure to immunosuppressive medications. The symptoms can be reversible if the offending etiology is quickly removed, but permanent deficits can remain if strokes or hemorrhage complicate the clinical course.

Abstract Background Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic encephalopathic state associated with reversible cerebral vasogenic edema. It is an increasingly recognized occurrence in the oncology population. However, it is very uncommon in patients with primary brain tumors (PBTs). The aim of this study was to analyze the clinicoradiological features and report the clinical outcomes of PRES in PBT patients. Methods We identified 4 cases with PBT who developed PRES at MD Anderson Cancer Center (MDACC) between 2012 and 2014. Clinical and radiological data were abstracted from their records. In addition, we also solicited 8 cases from the literature. Results The median age at PRES onset was 19 years, male-to-female ratio was 1:1, and the syndrome occurred in patients with ependymoma (n = 4), glioblastoma (n = 3), diffuse intrinsic pontine glioma (DIPG; n = 3), juvenile pilocytic astrocytoma (n = 1), and atypical meningioma (n = 1). Two glioblastomas and 2 DIPG cases received bevacizumab and vandetanib before the onset of symptoms, respectively. The most common clinical presentation was seizures (n = 7). Three MDACC patients recovered completely in 3–4 weeks after the onset of symptoms. One patient died due to active cancer and several comorbidities including PRES. Conclusions Hypertension seems to be the most important coexisting risk factor for development of PRES; however, the potential effects of chemotherapeutic agents in the pathogenesis of PRES should also be examined. The clinicoradiological course of PRES in PBT patients did not vary from the classical descriptions of PRES found in other causes. PRES must be considered as part of the differential diagnosis in patients with PBTs presenting with seizures or acute encephalopathy.

Reversible Encephalopathy

Objective: Posterior reversible encephalopathy syndrome (PRES) has been robustly associated with preeclampsia, hyperperfusion or endothelial dysfunction suggested as possible mechanisms. In this article, we report an illustrative case of this complication in a patient with risk factors for hypertensive disorders in pregnancy, including advanced maternal age and donor oocyte fertilization. Case report: We present a case of a 40-year-old pregnant, donor oocyte recipient with sudden decreased visual acuity accompanied by hypertension, proteinuria and tonic-clonic seizures. Magnetic resonance imaging (MRI) of the brain showed bilateral lesions in the parieto-occipital regions suggestive of vasogenic edema, leading us to suspect posterior reversible encephalopathy syndrome. The patient underwent an emergency cesarean section and labetalol and magnesium sulfate were administered intravenously. The neurological symptoms and radiological findings resolved following delivery and the patient’s blood pressure normalized, supporting the diagnosis of posterior reversible encephalopathy syndrome. Conclusion: Pregnancy by donor oocyte fertilization may entail a higher risk of eclampsia and associated posterior reversible encephalopathy syndrome.
