Adnexial Mass During Pregnancy: Case Rep

Abstract

The diagnosis of masses during pregnancy is mainly incidental and infrequent but has been increasing, along with the growing role of ultrasound in obstetric surveillance. Usually the masses are asymptomatic, benign, of ovarian origin and may have spontaneous resolution.
We present the case report of a 36-year-old woman, G1P0, 7 weeks pregnant, that went to the Emergency Service due to hypogastric pain and vaginal bleeding. An adnexal complex mass with 30 cm (largest diameter) was diagnosed by ultrasound. At 13 weeks of pregnancy, a left adnexectomy was performed by laparotomy, with no complications. The surgical specimen weighed 4955 g and the final histological report was compatible with an ovarian seromucinous cistadenoma.
The imaging exams allow us to understand characteristics that suggest if an adnexal mass is benign or malignant, which is important for the therapeutic decision process. The obstetric outcome is generally favourable.
