Ovarian masses ≥5cm in diameter have been found in only 0.04-0.05% of pregnant women. Most of the adnexal masses encountered during pregnancy are simple cysts <5cm in diameter and about 70% would resolve by the early second trimester. The persistent cysts with gradual increase in size required surgical management. Adnexal masses requiring surgical intervention in pregnancy have been reported for around 1% to 2.3% of all gestations. In the series we reviewed 6 cases at different trimesters of pregnancy with ovarian masses measuring ≥5cm that were managed surgically in a regional hospital in Oman. We observed the maternal perinatal outcome after removal of cysts either by Laparotomy or during cesarean delivery. Ovarian masses with acute complications warranted immediate surgical intervention irrespective of gestational age and incidental findings of ovarian masses during cesarean section required removal to avoid delayed diagnosis of malignancy and repeat surgery. spontaneously with no history of ovarian stimulation treatments. On general examination she was vitally stable. However abdominal examination revealed that a palpable mass at the middle of the lower abdomen corresponding to 20 weeks in size was tender on palpation. Baselines of all investigations were within normal limit. Eventually a radiology ultrasound revealed that the gravid uterus with intra uterine alive fetus corresponding to 8 weeks of gestation and a huge anechoic well defined cystic lesion in the middle of lower abdomen measuring 13.8x8.8cm with no doppler signal around it. Both ovaries were masked by the mass. Minimal amount of free fluid was seen in the pouch of Douglas. An urgent laparotomy was undertaken, during which a large unilocular thick walled right-sided ovarian cyst was detected measuring around 14x8.5cm in size (Figure 1). The cyst was twisted twice with clear fluid inside it. A right ovarian cystectomy was then carried out, and around 1700 ml clear fluid aspirated from the cyst. The remaining ovarian tissue and fallopian tube were preserved. Postoperatively she was placed on oral progesterone (Tab Dydrogesterone 10 mg BID) support upon hospital discharge. Histopathology report confirmed serous cyst adenoma in the ovary with signs of torsion. Tumor markers were within the normal limit. She was on regular ANC follow up which was uneventful. At 40 weeks and 1 day of gestation she delivered by a spontaneous vaginal delivery of a live baby of weighting 3 kg with Apgar score 9/1 minute and 10/5 minute.
