Posterior reverse encephalopathy syndrome with myriad of etiologies and presentations

Abstract

We hereby report cases of posterior reverse encephalopathy syndrome (PRES) with varying etiologies, presentations, and treatment outcomes. In this series, amongst four cases of PRES with sudden diminution of vision, two were male patients with high blood pressure, one was a case of pulmonary tuberculosis, and one case of imminent eclampsia. All patients were treated with respect to underlying etiopathology. Although appalling at presentation, the cases showed marked improvement clinically within the first week. There is need for high index of suspicion, and improvement of clinical condition suggests excellent prognosis in PRES cases.
