Thecalutein cysts during pregnancy: clinical cases

Thecalutein cysts are benign and quite rare pathology in pregnancy. The article presents clinical cases of large thecalutein cysts that occurred during pregnancy, first identified in the second trimester of gestation with different outcomes – complicated by spontaneous rupture of the ovary in the postoperative period and with a favorable outcome and spontaneous reduction of cysts after delivery. During dynamic follow-up, there was a progressive increase in the size of the neoplasm, with the maximum volume reached by the time of delivery at 37–38 weeks gestation in the first case, and an increase in ovarian formations in the second trimester, followed by volume stabilization by 32 weeks of gestation, at the time delivery was performed, in the second case. The postoperative period in the first clinical case was complicated by spontaneous cyst rupture with the development of intraabdominal bleeding on the first day of the postpartum period, which necessitated relaparotomy and adnexectomy. While in the second clinical case, the postoperative period was uneventful, a month later, a regression of ovarian formations was identified by control ultrasound examination.
