Posterior Reversible Encephalopathy Syndrome:  Two Cases of a Rare Complication of Hypertensive Disorders in Pregnancy

Hypertensive disorders in pregnancy are one of the leading causes of maternal and foetal morbidity and mortality. One of the rarest complications of preeclampsia and eclampsia is Posterior Reversible Encephalopathy Syndrome (PRES) also known as reversible posterior leukoencephalopathy syndrome. We report two cases of PRES occurring during pregnancy, characterised by headache and visual symptoms in the setting of preeclampsia. MRI brain scans showed involvement of the occipital, parietal, and cerebellar regions in both cases. One patient also had hypertensive retinopathy and optic disc haemorrhages. Multidisciplinary management included controlling high blood pressure, delivery, and follow-up care. Both patients recovered over weeks without permanent residual effects.
