Introduction/Background Objective : the objective of our study is to evaluate the place of ultrasound in the diagnosis of ovarian tumors, the contribution of the CA125 ultrasound couple, the place of laparoscopy and the distinction of benign and malignant pathology of the ovary.

Materials and methods retrospective study carried out over a period of 18 months and including 42 patients.

Results Out of 42 patients, 8 cases of malignant ovarian tumors and 3 cases of borderline tumors were found: 72.85% of the benign tumors were observed before 40 years of age, 42.85% of the malignant and borderline tumors were observed at an age higher than 40 years. Moreover, 71.41% of malignant tumors were observed in nulliparous women. Nine of our patients were postmenopausal and only two had benign tumors. According to the ultrasound data, 54.42% of the benign tumors were between 8 and 10 cm in size and all malignant tumors were larger than 10 cm. All malignant tumors were larger than 15 cm and 71.42% of them were larger than 20 cm. The CA 125 assay was pathological in 14 cases, 6 of which were indeed malignant. The laparoscopic diagnosis did not miss any malignant tumor. Only two presumed malignant tumors were benign on histology.

Conclusion In ovarian tumors, discrimination between benign and malignant pathologies remains the main objective. None of the above-mentioned means alone can affirm with certainty the nature of an ovarian mass. The combination of these various means makes it possible to select patients requiring special management.

Disclosures The information presented in this study is based on retrospective data and should be interpreted with caution. The findings and conclusions are specific to the study population and may not be generalizable to all cases of ovarien cancer.
