Abstract Background Exclusion of malignancy in ovarian mass is of paramount importance. It is the most crucial step after identification of a mass and it has a profound effect on the patient's management. So, a reliable method with which to differentiate a benign from a malignant ovarian mass would provide a basis for optimal preoperative planning and may also reduce the number of unnecessary laparotomies for patients undergoing treatment for benign disease. Objective The aim of our study is to highlight the role of magnetic resonance spectroscopy as a non-invasive technique which may effectively assist in differentiating benign from malignant ovarian masses. Patients and Methods This study included 20 patients with adnexal masses as suggested by preliminary pelvic ultrasound examination. referred from the Gynecology Department to the Radiology Department at Ain shams university hospitals. nine were benign, two were borderline, and six were malignant tumors and 3 were hemorrhagic cyst. Endometriosis, tubo-ovarian abscess. Results Our study revealed sharp choline peak in some benign as well as some malignant cases and so Cho peak could not help in the differential diagnosis between benign and malignant tumors, creatine, lipid and NAA were detected in both benign and malignant tumors, also Choline/Creatine Ratio fairly can differentiate between benign and malignant tumors with cut off point = 3.750 at sensitivity = 75.0% & specificity = 100.0% . Conclusion Our study had some factors that affect the results. First, the sample size were not enough to achieve a good results, second, diversity of samples and the complicated tumor histopathologic and morphologic features.
