EVALUATION OF ADNEXAL MASSES ON ULTRASOUND AND COLOR DOPPLER AND ITS HISTOPATHOLOGY CORRELATION

Abstract

Background: Accurate preoperative differentiation between benign and malignant
adnexal masses is crucial for optimal patient management. Doppler ultrasound offers
valuable insights into tumor vascularity, aiding in this differentiation.
Aim: To evaluate the diagnostic utility of Doppler indices—resistance index (RI) and
pulsatility index (PI)—in assessing adnexal masses, using histopathology as the gold
standard.
Methods: This study included 100 patients with clinically suspected adnexal masses
who underwent transvaginal and transabdominal Doppler ultrasound. Vascular
patterns, RI, and PI were recorded and compared with postoperative
histopathological diagnoses.
Results: Malignant masses showed significantly lower RI and PI values compared to
benign ones. An RI < 0.4 and PI < 1.0 were strongly predictive of malignancy.
Doppler findings demonstrated high sensitivity and specificity in predicting
histopathological outcomes.
Conclusion: Doppler ultrasound is a valuable, non-invasive tool in the preoperative
evaluation of adnexal masses. Low RI and PI are significant indicators of malignancy
and correlate well with histopathological results, enhancing diagnostic confidence
and clinical decision-making
