Abstract:
Background. Ovarian cysts are met in women of various ages, most commonly occurring during
a woman's childbearing years, pregnant women not being an exception. Moreover, studies
conclude that ovarian cancer is among top five types of cancers detected during pregnancy. The
latest data show that the incidence of ovarian cysts in pregnancy varies from 0.15 to 5.7%
malignancies ranging from 0.8 to 13%. Their evolution is frequently hard to predict, some cysts
stop growing or disappear, while other may rupture, torsion or cause the obstruction of the
delivery pathways. Only ovarian cysts at risk of complication are to be considered. These are
mainly ovarian cysts, which, whatever their echogenic features, have a size ≥5 cm. Their
prevalence is estimated between 0.5 and 2 per thousand of pregnancies.
