ABSTRACT
Adnexal masses are relatively common in women. Adnexal torsion is most frequent in benign tumors than in ovarian cancer. This chapter reviews the ability of transvaginal ultrasound for discriminating between the most common types of benign lesions arising from de ovary and tube, as well as management options. It addresses the role of ultrasound in diagnosing and managing adnexal torsion. Serous cystadenoma constitutes about 25% of all benign epithelial ovarian tumors arising from the ovary. Cystadenofibromas are relatively uncommon epithelial ovarian tumors. Mature teratomas are among the most frequent benign ovarian tumors and the most frequent nonepithelial germ cell derived ovarian tumors. Adnexal torsion may affect women of all ages, accounting for about 3% of gynecologic emergencies. Ovarian torsion is a clinically relevant emergency in gynecology. Ultrasound should be the first-line imaging technique for evaluating patients suspected of adnexal torsion.
