Atypical severe intrauterine growth retardation and affected placental function after COVID-19 infection.

This case report describes an atypical progression of pregnancy in a woman who was infected with COVID-19 in her second trimester and initially presented with signs of absent foetal movements. The foetus was diagnosed with severe intrauterine growth restriction and abnormal foetal Doppler flows. The condition slowly improved over months, and the pregnancy was terminated with an acute caesarean section in gestational week 35. Placenta was tested negative for SARS-CoV-2-nucleocapsid. Four days old, the child was found COVID-19-positive, but remained asymptomatic. This case is a rare example considering the improvement of placental function over time.
