Abstract
Objective: to identify the characteristic echographic features of benign ovarian tumors using the recommendations of the IOTA group.Materials and methods. Five articles published in the journal Ultrasound in Obstetrics & Gynecology for 2008–2019 were analyzed. Each article is devoted to a histologically verified pathology of the ovaries, representing four morphological variants of an ovarian tumor (strum, fibroma/fibrothecoma, uroepithelial tumor (Brenner's tumor) and cystadenofibroma, as well as endometrioma in pregnancy. The total number was 380 women. When describing pathological formations, the researchers used a single protocol recommended by the IOTA group. Evaluated twentyone parameters, including the morphology of the formation, the structure of fluid inclusions and the solid component, the presence of fluid in the retrouterine space and ascites, as well as the degree of tumor vascularization.Results. The analysis of the struma, fibroma (fibrothecoma), Brenner tumor, cystadenofibroma and endometrioma of pregnant women indicates that there are no reliable criteria for diagnosing the histological structure of the tumor, both by the age of the patients, the size of the formation, and by ultrasound signs. Hyperechoic inclusions, which are noted only in Brenner tumors, both benign and malignant, can serve as the only marker among the pathology under consideration. In the study of the listed benign neoplasms of the ovaries, no features of the blood supply were revealed. All neoplasms had vascularization from the complete absence of vessels (1 point) to their moderate number (3 points). Hypervascularization (4 points) occurred in struma, fibroma (fibrotecoma), and cystadenofibroma.Conclusions. The task of ultrasound examination is the timely detection of an ovarian tumor with a presumptive conclusion of the probability of malignancy, based on standardized protocols of the IOTA group, which is important for the correct routing of the patient.
