BACKGROUND: An adnexal mass is a common gynaecological problem. Hence evaluation of adnexal mass is of particular importance in gynaecological practice and often present diagnostic and management dilemma.The aims and objectives of the study were to find out different types of adnexal pathology clinically, correlation of clinical finding with histopathology, correlation of ultrasonography finding with histopathology. METHODS: The study was carried in the Department of Obstetrics and Gynecology,Gandhi medical college from 1st February 2019 to 31st January June 2021. This study was a hospital based observational study which included 150 patients . All cases underwent an ultrasound examination . Following surgery, specimens were sent for histopathological examination and the reports were correlated with pre-operative clinical and ultrasonography findings. RESULTS:The most common site of origin of adnexal mass was Fallopian tube(56 %) followed by ovary (42.7%) .Clinical examination had a sensitivity and specificity of 66.66 % and 96.29 % in detecting malignant mass, respectively.In a comparison of HPE and USG diagnosis, the lowest sensitivity (75%)nd specificity (93.2%) was seen in benign ovarian lesions while the highest (sensitivity86.66%,specificity98.51%) was for malignant lesions. CONCLUSION: USG is recommended as a primary modality for diagnosing adnexal masses.For a definitive diagnosis and management of an adnexal mass, a multifaceted diagnostic approach should be used.
