Posterior Reversible Encephalopathy Syndrome (PRES) as a Differential of Sepsis and Isolated Pons Hyperintensity: A Case Report

Posterior reversible encephalopathy (PRES) is a clinico-neuroradiological transient entity with atypical clinical presentation and hyper-intensities in posterior regions of brain on T2 weighted sequence in magnetic resonance imaging. A well-known condition among neuro-radiologists, PRES is still unfamiliar to many intensive care clinicians. Delay in diagnosis may lead to additional morbidity and prolonged ICU stay. So the intensivists should be well aware of this syndrome since prompt recognition and precocious treatment have prognostic implications. We present an unusual case of PRES in association with sepsis and an atypical MRI finding of isolated pontine lesion.
