Abstract

Objective: The objective of this study is to evaluate the transvaginal ultrasound and colour doppler sonography for differentiation between benign and malignant adnexal masses.

Methods: In this study total 100 patients were selected from gynaecology OPD. At the end of this study there were 84 patients left and with some having bilateral adnexal masses, so total of 112 adnexal masses were evaluated. The transvaginal ultrasound (TVS) was used to study morphology of the adnexal masses and scoring was assigned using De Priest scoring system. The colour doppler study (CD-study) evaluates the presence or absence of blood flow within the adnexal mass, whether the flow is central or peripheral and the resistance index of the flow. The combined TVS morphological scoring and colour doppler study (TVS+CD) were used for evaluating the adnexal masses. The confirmatory diagnosis was made either by histopathological examination or fine needle cytological examination. The accuracy of TVS-morphological study and colour doppler sonography for differentiation of adnexal masses were assessed by calculating sensitivity, specificity, positive predictive value and negative predictive value.

Conclusion: TVS-morphological scoring is one of the best tools for adnexal mass evaluation but when it is combined with colour doppler sonography its diagnostic accuracy increases.

Keywords: transvaginal ultrasound, colour doppler sonography, adnexal masses.
