OP09.06: Ultrasound diagnosis and outcome of ovarian masses in pregnancy: a single centre prospective study

Ovarian masses are detected incidentally in pregnancy during routine obstetric ultrasound examination. Majority of these patients are managed expectantly, unless there are complications such as ovarian torsion or there is suspicion of malignancy. The aim of this study was to see the outcome of the ovarian masses seen in patients coming for their routine obstetric scans. It was a prospective study performed at our institution between 12.12.2018 and 12.12.2021where 61 pregnant women were included in this study who underwent first trimester 11-14 weeks ultrasound scan and were found to have an ovarian mass. Women with corpus luteal cysts were excluded from the study. We looked for the prevalence, size, ultrasound features and the subsequent management of these ovarian masses seen during the pregnancy. Out of 61 women 53 women (86%) did not require any surgical intervention. 8/61 women (19%) underwent surgical intervention for torsion during pregnancy. Out of 53 women the most common diagnosis was a mature teratoma in 25, epithelial neoplasms in10, decidualised endometriosis in 8 and borderline tumours in 4 women. Two women one with krukenberg and serous cytsadenocarcinoma died during pregnancy despite chemotherapy. Four women lost to follow-up. The recent advances in routine imaging during pregnancy have led to an increased rate of detection of ovarian masses. The management of ovarian masses in pregnancy depends on the presence of clinical symptoms or imaging findings Most were managed conservatively with follow-up ultrasound.
