Introduction:The evaluation of the female pelvis is a radiological challenge due to the large consortium of differential diagnosis in terms of the origin of masses it houses. In the general population, the prevalence of adnexal lesions is 0.17%-5.9% in asymptomatic women and 7.1%-12% in symptomatic women. The radiological modalities used in evaluation are Ultrasonography,Computed Tomography and MRI. This study strives to demonstrate the role of USG and CT together in detecting the gynecological pelvic lesions,characterize them,evaluate the findings which can differentiate malignant and benign lesions and assess their diagnostic efficacy. Material and methods: This was a prospective study done in the Department of Radiology,RMCH,Bareilly, from November 2016-2018. All the patients of suspected pelvic mass in the age group 15-45 years in stipulated period fulfilling the inclusion criteria were enrolled for study. Results: Ovarian masses were most frequent (66%), followed by uterine (22%) and adnexal masses accounted for 12% of the cases. 38% of the ovarian masses were cystic, 36% were solid and rest 26% were mixed solid-cystic lesions. In uterine lesions, leiomyoma was found to be the commonest (45.5%). Conclusion: Of all pelvic gynecological masses,ovarian masses were the commonest.Transvaginal sonography and transabdominal sonography were very efficacious in diagnosis of gynecological masses and were diagnostic in 93.1% and 88% cases respectively. Computed tomography was diagnostic in 78% of cases.
