Unusual presentation of PRES in the postnatal period.

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological entity, associated with a vast array of medical conditions and a variety of presenting symptoms. There is a characteristic pattern of radiographic features alongside suggestive clinical manifestations, which lead to a diagnosis of PRES. This report describes the case of a 39 years old, previously normotensive woman, who presented on day 7 postpartum with generalised tonic clonic seizures, reduced conscious level and a history of blurred vision and headache. She was treated immediately as eclamptic and transferred to the intensive care unit for stabilisation. Following an inconclusive CT result, an MRI was performed 2 days after presentation, which demonstrated white matter changes consistent with those found in PRES. She made a full recovery and a repeat MRI scan 7 weeks later showed no progression of the lesions noted on the original scan. 2014 BMJ Publishing Group Ltd.
