Chronic Glomerulonephritis and Malignant Hypertension With PRES (Posterior Reversible Encephalopathy Syndrome) Presenting As Status Epilepticus: A Case Report

Choroidopathy and Retinal Detachment: A Rare Sighting in a Case of Postpartum Hemorrhage Presenting With Posterior Reversible Encephalopathy Syndrome

Posterior reversible encephalopathy syndrome (PRES) is a rare syndrome characterized by convulsions, headache, fatigue, impaired mental status, and decreased vision. It is mainly accompanied by hypertension. Although the pathophysiology of PRES is unknown, some theories revolve around cerebral autoregulation, the ability to maintain cerebral blood flow, or the brain's ability to maintain steady cerebral blood flow over a varying range of blood pressures by cerebral vaso-constriction or dilation. The presence of subcortical vasogenic edema in the posterior brain and hyperintensity lesions in the occipital and parietal lobes on magnetic resonance imaging (MRI) of the brain is diagnostic. We present the case of a woman who acquired PRES after a postpartum hemorrhage with no underlying disease, eventually leading to a choroidopathy and sudden onset diminution of vision, early diagnosis of which saved the patient from the catastrophic complication of permanent blindness.

Beyond the Shadows: Unravelling the Menace of Methanol-Induced Posterior Reversible Encephalopathy Syndrome

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological illness characterized by neurological symptoms and reversible changes in neuroimaging. We discuss the case of a 45-year-old patient with an alcohol use disorder who presented with an altered mental state in the emergency room. Home-made alcohol, known to contain significant quantities of methanol, was recently consumed in excess by the said patient. The diagnosis of PRES was supported by magnetic resonance imaging (MRI), which showed bilateral hyperintense regions in the temporo-occipital lobes and diffuse cerebral edema. The development of PRES and chronic alcoholism, as well as binge drinking and possible endothelial dysfunction, are all highlighted in this case study. For individuals with PRES, early identification and adequate care are essential for reducing complications and improving outcomes.
