A neonatal case of cerebral venous sinus thrombosis with intrauterine onset after COVID-19 infection during pregnancy: Cause or coincidence?

Coronavirus 19 disease (COVID-19) is known to predispose patients to increased thrombotic events and the risk is higher in pregnancy which is already a hypercoagulable state. Vertical transmission of the disease during pregnancy was neglected according to data early in the pandemic, however, despite conflicting results from different studies, there is an increasing suspicion of vertical transmission with the rise of new fetal and neonatal cases and perinatal transmission can be higher than expected. An early term neonate, with the history of maternal COVID-19 infection in the start of third trimester, was diagnosed as cerebral venous sinus thrombosis and chronic hemorrhagic ischemia, with intrauterine onset.
