Abstract
Hyperreactio luteinalis is a rare condition characterized by ovarian enlargement due to multiple theca-lutein cysts and likely associated with elevated human chorionic gonadotropin (hCG) levels or an abnormal ovarian response to hCG [1]. Hyperreactio luteinalis is most often seen in conditions with elevated hCG levels, such as trophoblastic disease, multiple pregnancy, or nonimmune hydrops fetalis, but can also occur in normal singleton pregnancies [2]. This article presents a clinical case of large theca-lutein cysts that developed in the third trimester of pregnancy with a favorable outcome. During follow-up until delivery at 37-38 weeks, a progressive increase in the size of the ovarian cysts was noted. A partial resection of both ovaries was performed during a cesarean section. The postoperative period was uneventful, and a follow-up ultrasound two months later revealed complete regression of the theca-lutein cysts.
