Aim: Evaluation of ovarian masses with B mode ultrasonography and Doppler flow imaging to define various benign and malignant lesions. Material and Methods: The present hospital based observational study was conducted on 30 patients referred from Gynecology and Surgery department from October 2018 to September 2019. Results: Out of 30 cases, 27 were diagnosed as Benign, rest 03 were diagnosed as Malignant. Out of 27 benign cases, 12 were Mucinous cystadenoma,09 were Serous cyst adenoma and 06 were Dermoid. The Ovarian-Adnexal Reporting and Data System (ORADS) lexicon for US was published in 2018, providing a standard that includes all descriptors and definitions of the characteristic USG appearance of normal ovaries and ovarian or other adnexal lesions Conclusion: Using the categories of size, unilocularity or multilocularity, solid components, papillary projections, acoustic shadows and blood flow it is possible to recognize typical cases of each category which results in confident and specific diagnoses of ovarian lesions.
