OVARIAN OVERSTIMULATION IN PREGNANCY

We report on the extremely rare case of ovarian overstimulation in a s ingle pregnancy without prior hormonal stimulation therapy. During the 26th week of gestation ultrasound examination showed a 103 x 51 x 78 mm polycystic tumour with echogenic structures inside the cysts, locat ed behind the uterus. Further management consisted of laparotomy with partial resection of a cystic part of the left ovary. Frozen section e xamination confirmed the diagnosis of hyperreactio luteinalis and excl uded malignancy. To avoid torsion of the ovaries, cysts from both side s were aspirated. On day 8 and 18 after surgery, sonography revealed n o pathological finding. In the 40th week of gestation, a healthy baby was delivered. The possiblity of a hyperreactio luteinalis has to be k ept in mind, when cystic solid tumours of the ovaries are diagnosed du ring pregnancy. A conservative management is appropriate, because a no rmal spontaneous remission occurs after delivery.
