Posterior Reversible Encephalopathy Syndrome: ‘A headache’ on the AMU

Abstract

Headache and seizures are common presentations to the acute medical unit. We report a case of posterior reversible encephalopathy syndrome (PRES) in a 73 yr old woman with a history of uncontrolled hypertension who had recently discontinued one of her antihypertensive drugs; such cases are rare but pose a diagnostic challenge given the nonspecific nature of the clinical presentation. However, early diagnosis and treatment leads to full recovery in the majority of patients.
