[Severe hydrops fetalis in a first trimester pregnancy with Ulrich-Turner syndrome]

We report about a case of abundant hydropic evolution of a fetus in the first trimester of gestation. Already in the 8th week of gestation we diagnosed the first references of failure with transvaginal ultrasound. In the following three weeks we observed the progression of the hydrops. The genetic research of fetal tissue after induced abortion show the karyotype 45 X0.
