Subjective Sonographic Assessment for Differentiation between Malignant and Benign Adnexal Masses


Objective: To determine the accuracy of subjective sonographic assessment in distinguishing between benignand malignant adnexal masses. Study design: Cross-sectional descriptive study.
Methods: The patients scheduledfor elective surgery due to adnexal masses were recruited into the study. All patients were sonographicallyexamined within 72 hours of surgery were subjectively evaluated by the experienced sonographer, who had noany information of the patients, to differentiate between benign and malignant adnexal masses based onsonographic morphology. The final diagnoses, used as gold standard, were based on either pathological oroperative findings.
Results: One hundred and fifty-eight patients with 174 adnexal masses, (benign; 108 andmalignant; 66) were recruited into the study. The accuracy, sensitivity, specificity, positive predictive value, andnegative predictive value were of 89.7%, 84.9 % and 92.6 %, 87.5% and 90.9%, respectively.
Conclusions:Subjective evaluation of sonographic morphology has high accuracy in differentiating between benign andmalignant adnexal masses.
