We present a case of intrauterine parvovirus B19 infection, diagnosed by detection of B19 DNA in the amniotic fluid obtained at 15 weeks of gestation for chromosome analysis in an asymptomatic pregnancy, causin g hydrops fetalis 7 weeks later. Following intrauterine transfusion, r apid resolution of hydrops could be observed and a healthy boy was bor n at 38 weeks of gestation.
