ABSTRACT

Background: Adnexal masses of pregnancy are incidental findings during pregnancy. They are usually diagnosed with first trimester ultrasound. Their incidence and clinical course vary depending on the weeks of pregnancy. The most common complication is torsion with acute abdomen. The incidence of torsion ranges from 0.2 to 15%, with an increase during pregnancy with larger masses. They are rare during the third trimester of pregnancy. Mucinous cystoadenomas are among the most frequent benign epithelial tumors of the ovary; they are considered precursors of mucinous carcinomas.
Clinical case: 34-year-old female patient, with obstetric history of four pregnancies: two deliveries and two miscarriages, 31 weeks pregnant on admission to the Hospital Universitario de la Samaritana of Colombia, justified by a clinical picture of 18 hours of evolution consisting of: intense abdominal pain, stabbing type, predominantly in the right iliac fossa and flank. At laparotomy the torsion was found and resected. The anatomopathological study reported "mucinous tumor of endocervical type with severe infarction changes". Maternal perinatal evolution was satisfactory.
Conclusions: The diagnosis of adnexal mass torsion as a cause of acute abdomen in the third trimester of pregnancy is complex as it requires clinical history, imaging and paraclinical studies. The maternal-perinatal prognosis is good when medical-surgical treatment is timely. It is necessary to determine the type of mass with anatomopathological studies to continue the integral treatment. Mucinous ovarian tumor, endocervical type in twisted ovarian masses, is rare.
