Acute onset of blindness associated with posterior reversible encephalopathy syndrome: A HELLP syndrome case report

Posterior reversible encephalopathy syndrome (PRES) is an uncommon disorder. PRES presents with clinical findings such as headache, seizures, visual disturbances, and altered consciousness. Here, we present a PRES case in the second trimester of pregnancy with intrauterine fetal demise. A 40-year-old woman, gravida 4 para 3, was diagnosed with HELLP syndrome based on the clinical and laboratorial findings. An emergent caesarean section was performed under magnesium sulphate (MgSO4) treatment. She had suffered vision loss with normal fundoscopic findings at postpartum period. All the clinical, laboratory and imaging findings (MRI) confirmed the diagnosis of PRES. Careful observation of the clinical findings and prompt treatment is necessary for pregnancies complicated by PRES to prevent undesirable outcomes.
