Posterior reversible encephalopathy syndrome: a report of a case with atypical features

Summary We report a case of a young woman presenting with profound depression of consciousness and intra‐uterine death in the late stages of an unbooked pregnancy. She proceeded to develop features of cardiovascular, renal, hepatic and haematological failures. The patient was challenging to manage in view of uncertainty regarding the underlying cause, and required multidisciplinary consultation. A diagnosis was subsequently made of posterior reversible encephalopathy syndrome in the context of pre‐eclampsia. We review the typical presentation and wide‐ranging associations of this recently described clinico‐neuroradiological syndrome, and look at how appropriate management may lead to rapid resolution of its often life‐threatening features. We highlight the importance to anaesthetists and critical care physicians of recognising even atypical cases such as this one in view of key differences in management from similarly presenting conditions.
