Classification of ovarian lesions by high-frequency transvaginal sonography

Two hundred patients suspected of having ovarian pathology were scanned with a 6.5-MHz transvaginal probe. Normal anatomical structures and abnormal findings were recorded and classified according to their shape, size, location, and sonographic characteristics. The sonographic images were correlated with the surgical findings, whenever available. A sonographic classification of ovarian lesions was compiled according to the presence or absence of the following sonographic components: septae, papillae, loculations, daughter cysts, solid mass, or fluid, and their relationship to malignancy.
