This study aimed to present the diagnosis and management of adnexal masses of <6 cm in full-term pregnancy at a primary-level hospital. We present two cases of adnexal torsion. Cases 1 and 2 were conservatively managed for masses measuring 44.4×30.5 mm and 49.4×34.3 mm in the first trimester, and the patients experienced acute-onset serious abdominal pain at 39 and 37 weeks of gestation, respectively. Emergency cesarean section and unilateral salpingo-oophorectomy were performed. Histopathology confirmed serous cystadenoma with ischemic changes in both cases. Our findings suggest that clinical information regarding adnexal masses in the first trimester and their clinical symptoms can inform management decisions in the third trimester.
