ABSTRACT
Background: Ovarian cancer has emerged as one of the most common malignancies affecting women in India. Amultidisciplinaryapproach is needed for the optimal management of patients presenting with adnexal mass wherein the radiologist and thepathologist play an important role in assisting in clinical decision-making. The present study is done to correlate the ultrasoundfindings with the histopathological findings and to study the whole spectrum of adnexal masses.Methods: This is a prospective observational study carried out on 60 patients with adnexal masses and pre-operative ultrasoundassessment and who underwent surgical resection of their masses in a tertiary care center.Results: The pre-menopausal age group was more frequently affected than post-menopausal age group. A large number ofadnexal masses were of ovarian origin. The incidence of neoplastic adnexal masses is much higher than the non-neoplasticmasses. Among the neoplastic adnexal masses majority were ovarian tumors. The incidence of benign ovarian tumors is higherthan malignant tumors. Among the malignant tumors, serous cystadenocarcinoma was the most common tumor. Majorityof the ovarian tumors diagnosed by ultrasonography (USG) as purely cystic in architecture were proven benign tumors onhistopathology. Of the solid-cystic tumors, 50% were benign, and 50% malignant on histopathology solid architecture of thetumors was the least common, and the majority were malignant. USG diagnosis of adnexal masses revealed a sensitivity of94.4%, specificity of 83.3%, positive predictive value of 70.8%, and negative predictive value of 97.2%.Conclusions: USG is a sensitive and specific modality in pre-operative diagnosis of the malignant nature of lesions. Thepresence of solid component in an ovarian mass was a highly accurate predictor of malignancy.
