Sonography of Adnexal Masses

Transabdominal sonography combined with high-frequency endovaginal ultrasound is considered the community standard for the performance of pelvic ultrasound for evaluation of an adnexal mass. Subjective evaluation of ovarian masses based on pattern recognition can achieve a sensitivity of 88% to 100% and specificity of 62% to 96%. Addition of color and power Doppler to grayscale imaging for pelvic mass evaluation increases the specificity in the range of 82% to 97% and increases the positive predictive value to 63% to 91%, aiding in subsequent evaluation and management. Pelvic sonography can confidently diagnose most of the benign adnexal masses and helps with triage of patients for surgical management in collaboration with tumor markers.
