Introduction: Posterior Reversible Encephalopathy Syndrome (PRES) is clinico-neuro-radiological adversity associated with headache, vomiting, altered mentation, and seizures, with acute to sub-acute presentations. Diagnosis is by MRI. The condition is often reversible but increases morbidity.
Case series: We report three cases of unusual presentation of Posterior Reversible Encephalopathy Syndrome that followed hypertension in early pregnancy without seizures.
Conclusion: Posterior Reversible Encephalopathy Syndrome may present in women with early-onset or pre-existing hypertension. It must be included as one of the differential diagnoses in pregnant women having hypertension early in pregnancy and early fetal loss even in the absence of seizures.
Key words: Hypertensive encephalopathy, PRES, Early onset hypertension
