Adnexal masses in pregnancy

Abstract

Objectives: The objective of this case is to present a rare case of maternal ovarian mucinous cystadenocarcinoma during pregnancy and its outcome. Only 0.05-2.4% of pregnancies are complicated by an adnexal mass, and approximately 1-6% of these masses are malignant. The majority of ovarian masses are diagnosed by a routine ultrasound examination or cesarean delivery. Adnexal masses less than 5cm usually are benign and in 70% of cases spontaneously resolve by the second trimester while the adnexal masses 5 cm or greater are dermoids and 10% found in pregnancy are malignant. One-half of all ovarian malignancies in pregnant women are epithelial ovarian tumors. Material and Methods: We present a case of 27-year-old pregnant women who was incidentally diagnosed by ultrasound examination with a large multilocular cystic adnexal mass in right ovarium at the first trimester (ml III) with diameter 88x85mm which enlarged to 88x140mm at third trimester (ml X). In week 40 of pregnancy, the patient gave birth to a healthy baby through cesarean section, during that was performed and right salpingo-oophorectomy, Results: The pregnancy was terminated at term with good pregnancy outcome. The histopathology report of right salpingo-oophorectomy describe mucinous cystadenocarcinoma of the right ovarium Stage IA according to FIGO classification. Conclusion: Surgical intervention and histological examination of persisting adnexal lesion are often necessary, even during pregnancy.
