[Prenatally reported fetal ovarian cysts--treatment and prognosis]

We present 6 case reports of ovarian cysts, diagnosed in the prenatal and postnatal period, as well as treatment. There was no need for invasive prenatal therapy in any of the reported fetuses. Most of the cysts disappeared spontaneously (in one case uncomplicated cyst rupture in fetus have been observed), only in one case laparoscopy was performed after birth.
