Role of Ultrasound in the Diagnosis of Adnexal Torsion

Abstract

Ovarian torsion refers to the complete or partial rotation of the ovary on its ligamentous supports, often resulting in impedance of its blood supply. It is one of the most common gynecologic emergencies and may affect females of all ages. The fallopian tube often twists along with the ovary; when this occurs, it is referred to as adnexal torsion. Prompt diagnosis is important to preserve ovarian and/or tubal function and to prevent other associated morbidity. However, making the diagnosis can be challenging because the symptoms are relatively nonspecific. Case report and literature review. A 53-year-old female denied any systemic disease before. She was suffered from lower back pain for one month. Severe lower abdomen cramping attacked suddenly thus she was sent to emergency room. Transabdominal ultrasound showed a huge mass over lower abdomen, and a right adnexa mass torsion was proved after emergency operation. This case illustrates transabdominal ultrasound can be used in diagnosis of adnexal mass torsion, especially in childbearing age woman who is not sure about pregnancy. This could prevent radiation exposure accompanied with more advanced image examination.
