A New Insight on Exophytic Serous Borderline Adnexal Tumors: Specific Sonographic Features.

Objectives: To characterize and compare the sonographic features of exophytic serous borderline ovarian tumors (ESBOT) with those of high-grade serous carcinoma of the ovary (HGSC).

Methods: Seven patients with histological diagnosis of ESBOT diagnosed between 2011 and 2019 and 10 consecutive cases of HGSC detected during 2019, both depicting an exophytic growth pattern, were identified retrospectively. The sonographic imaging of the masses was reassessed and characterized according to the International Ovarian Tumor Analysis terms.
