Volumes of normal ovaries, ovaries with benign lesions, and ovaries with cancer in menopausal women: is there an optimal cut-off value to predict malignancy?

Purpose: To evaluate different ovarian volume cut-off values to distinguish between normal ovaries, benign lesions, and malignant lesions in menopausal women.

Methods: Transvaginal sonographic ovarian volume measurements were performed in 362 menopausal patients prior to gynecologic surgery. Based on the histopathologic results, a total of 466 ovaries were divided into 3 groups: normal ovary, benign lesion, and malignant tumor.
