Role of ultrasonography and CT in diagnosing different types of adnexal masses and correlation with histopathological report
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2016, Vol 20, Issue 2
Abstract
Aims and objectives: To study the ultrasonography pattern of various adnexal masses and correlate them with histopathological findings. The computed tomography patterns of various adnexal masses and correlate them with histopathological findings. The complementary role and drawbacks of USG and CT modalities in evaluation of adnexal masses. The sensitivity, specificity, PPV, NPV ,diagnostic accuracy of USG and CT in differentiating benign from malignant adnexal masses. The sensitivity, specificity, PPV, NPV, diagnostic accuracy of USG and CT in differentiating solid and cystic adnexal masses. Methods: This is a prospective analysis of 50 patients referred from in patient ward as well as outpatient for USG and CT scan in our institute for evaluation of suspected adnexal masses. Findings of USG and CT scan were computed and compiled. Result: The results of the study revealed that the ovarian masses constituted 96% and fallopian tube masses ,4% of all adnexal masses. Among the ovarian masses, malignant lesions were 48%,benign lesions were 37.5% and borderline lesions were 14.5%.USG showed sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 96%, 92%, 92%, 95.8% and 94%in determining cystic nature of the lesions.CT was found to have 96% sensitivity, 94% specificity, 96% positive predictive value, 94% negative predictive value and 95% accuracy in differentiating benign from malignant masses. Conclusion: CT is a better modality than USG in lesion detection, differentiating benign from malignant lesions, assessing local extension, vascularity of lesions, detection of lymphadenopathy and distant metastasis in both adnexal lesions.USG is a better modality in assessing cystic nature of the lesions. Improved detection and characterization of adnexal masses contribute to better diagnostic accuracy and consequent reduction of false positive findings and invasive procedures which leads to significant reduction in mortality and morbidity.
