Adnexal Diseases

Abstract

AbstractAdnexal masses may present as symptomatic lesions or be discovered incidentally during radiological examinations. The questions asked of radiologists are firstly, what is the nature of the mass and secondly, does it need to be removed and if so, how? Multidisciplinary discussion is to plan patient management and aim to avoid the two scenarios of simple resection of an ovarian cancer and major debulking surgery for benign disease.Ultrasound (US) is excellent for characterisation of many common benign pathologies, but benign disease can present with complex appearances that are sonographically indeterminate. The widespread use of computed tomography (CT) as first-line investigation in many clinical settings has resulted in diagnosis but limited characterisation of adnexal lesions.Magnetic Resonance Imaging (MRI) has a crucial role to play as a problem-solving tool. The ability to confirm the organ of origin and give information on the nature of contents of a lesion allows confident diagnoses to be made, and an algorithmic approach to this has been described in the Ovarian-Adnexal Reporting and Data System (O-RADS) MRI scoring system.
