Ovarian cysts and adnexal masses are among the most common indications for pelvic ultrasound in women. Ultrasound is the primary imaging modality for evaluating adnexal masses, characterizing them as simple cysts, complex cysts, or solid masses to guide clinical management.
Risk Stratification
The O-RADS (Ovarian-Adnexal Reporting and Data System) classification system standardizes adnexal lesion reporting and provides risk stratification for malignancy. Sonographic features assessed include size, composition (simple cystic, complex, solid), internal vascularity, and wall characteristics.
