Preeclampsia with posterior reversible encephalopathy syndrome and cerebral venous sinus thrombosis in a pregnant patient with COVID-19

Since its discovery in December 2019, coronavirus disease 2019 (COVID-19) has been linked to a variety of systemic effects in addition to pulmonary involvement. Pregnancy increases the risk of severe COVID-19 symptoms. COVID-19 during pregnancy worsens maternal and fetal outcomes such as preterm delivery, preeclampsia, and vascular complications. Herein, we report the case of a pregnant woman with COVID-19 who developed preeclampsia, posterior reversible encephalopathy syndrome (PRES), and cerebral venous sinus thrombosis (CVST) in the peripartum period. We discussed the possible link between these neurological complications and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Headache can be observed in the natural course of SARS-CoV-2 infection; however, it can also result from numerous etiologies such as preeclampsia, PRES, and CVST in the peripartum period. An accurate diagnosis is crucial, as the treatment and prognosis of each differ.
