Analysis of 49 cases of prenatally diagnosed ovarian cysts are presented. The outcomes of prenatally diagnosed ovarian cysts were studied on their antenatal ultrasound and MRI images. Outcomes analysis of fetal ovarian cysts depending on their ultrasound and MRI features are presented. Prenatal features, complications of pregnancy, cysts evolution, outcomes and postnatal surgical intervention on 49 cases of fetal ovarian cysts are presented. 1/3 of the ovarian cysts were visualized partly or completely in the abdomen, 1/3 — laterally from the bladder. Simple cysts were of less dimension compared to complex lesions. Increase in size is presumably of higher risk of complications. Spontaneous regression by the time of delivery was in 34.7%. 100% of lesions  2 cm disappeared, the rate of regression of simple and complex cysts was equal, the lowest rate of regression was seen in cysts  4 cm. The frequency of surgical treatment was in 26.5%.
