Abstract
Objective: To analyse prenatal diagnosis, management, and pregnancy outcomes in fetuses with an ovarian cyst and compare our results with foreign literature. Methods: Retrospective analysis including fetal ovarian cysts diagnosed in the years 2017-2021 in our centre.
The size and appearance of the cyst in relation to pregnancy outcome and pre-and post-natal management were evaluated. Results: In the years 2017-2021, we have examined 5 420 pregnancies and 7 ovarian cysts were detected.
Cysts were divided into smaller and larger than 4 cm and simple and complex. 3 cysts were ≥ 40 mm, 4 cysts < 4 cm, 2 cysts were complex, the remaining 5 were simple. Prenatally, conservative management was chosen for all cysts. 4 cysts (57 %) disappeared during pregnancy, 1 after delivery (14 %), in 2 cases postnatal surgical intervention was necessary – 1× cyst puncture and 1× ovariectomy (28 %).
Both cysts requiring postnatal intervention were larger than 4 cm, one simple and one complex. Conclusion: Ovarian cysts are a congenital defect with a good prognosis, majority of them resolves spontaneously during pregnancy or postnatally.
The size and type of the cyst are directly related to the likelihood of the cyst disap-pearing. Our management and results are in agreement with world literature.
