A rare case of fatal intractable posterior reversible encephalopathy syndrome in a male child

Abstract

Posterior reversible encephalopathy syndrome (PRES) is a neurological condition characterized by disruption of cerebrovascular autoregulation. Diverse etiologies with acute hypertension as common component can lead to PRES. The condition is usually but not always reversible. Here we present a rare case of fatal PRES which shows radiological features of different stages of PRES from normal to overt intracerebral hemorrhage (ICH) and emphasizes the importance of radiologist familiarity with neuroimaging of different stages of this entity. © 2025 The Author(s);.
