The Role of Imaging in the Evaluation of Adnexal Masses

Background: Imaging plays a major role in the detection, diagnosis, and ultimate treatment strategies of adnexal masses. As high as 10% of women in the United States undergo surgical evaluation for a suspected adnexal neoplasm. Objective: To understand the advantages and disadvantages of each imaging modality used in the evaluation of adnexal masses. Results: Ultrasound is frequently the imaging modality of choice for initial characterization. Computed tomography, magnetic resonance imaging, and positron emission tomography – computed tomography are frequently employed if malignancy is suspected to assess for metastasis. Conclusion: A basic understanding of adnexal imaging modalities will be of benefit to care providers and, in turn, be of benefit to patients.
