Background/Aim. Not only that ultrasound makes the difference between cystic and solid changes in breast tissue, as it was the case at the beginning of its use, but it also makes the differential diagnosis in terms of benign-malignant. The aim of this study was to assess the role of sonography in the diagnosis of palpable breast masses according to the American College of Radiology Ultrasonographic Breast Imaging Reporting and Data System (BI-RADS) and to correlate the BI-RADS 4 and BI-RADS 5

A retrospective study was conducted with the breast sonograms of 30 women presented with palpable breast masses found to be mammography category BI-RADS 0 and ultrasonographic BI-RADS categories 4 and 5. The sonographic categories were correlated with pathohistological findings. Results. Surgical biopsy in 30 masses revealed: malignancy (56.7%), fibroadenoma (26.7%), fibrocystic dysplasia with/without atypia (10%), lipoma (3.3%) and intramammary lymph node (3.3%). Correlation between BI-RADS categories and pathohistological findings was found (p < 0.05). All BI-RADS 5 masses were malignant, while in BI-RADS 4A category fibroadenomas dominated. A total of 53.8% of all benign lesions were found in women 49 years of age or younger as compared with 35.3% of all malignancies in this group (p < 0.05). Conclusion. Ultrasonography BI-RADS improved classification of breast masses. The ultrasound BI-RADS 4 (A, B, C) and BI-RADS 5 lesions should be worked-up with biopsy. predictive value of tests; risk assessment. Apstrakt Uvod/Cilj. Ultrazvučnim pregledom može ne samo da se napravi razlika između cističnih i solidnih promena u tkivu dojke, kao što je bilo na početku njegove primene, već i da se napravi diferencijalna dijagnoza u smislu razlikovanja benignih od malignih promena. Cilj rada bio je procena uloge ultrazvuka u dijagnostici palpabilnih promena u dojci u skladu sa terminologijom Breast Imaging Reporting and Data Systems (BI-RADS) i korelacija kategorija BI-RADS 4 i BI-RADS 5 sa patohistološkim nalazom. Metode. Retrospektivna studija sprovedena je u grupi od 30 žena sa palpabilnim promenama u dojci, sa mamografskom kategorijom BI-RADS 0 i ultrazvučnim kategorijama BI-RADS 4 i 5. Sonografske kategorije su korelisane sa patohistološkim nalazom. Rezultati. Eksciziona biopsija 30 promena je pokazala: malignitet (56,7%), fibroadenom (26,7%), fibrocističnu displaziju sa ili bez atipije (10%), lipom (3,3%) i intramamarni limfni nodus (3,3%). Korelacija između BI-RADS kategorija i patohistološkog nalaza je dokazana (p < 0,05). Sve BI-RADS 5 promene bile su maligne, dok je u BI-RADS 4A kategoriji dominirao fibroadenom. Ukupno 53,8% svih benignih promena pronađene su kod žena starosti 49 godina ili mlađih u poređenju sa 35,3% malignih promena u ovoj grupi (p < 0,05). Zaključak. Upotreba ultrazvučne BI-RADS nomenklature poboljšala je klasifikaciju promena u dojci. U slučaju ultrazvučnih kategorija BI-RADS 4 (A, B, C) i BI-RADS 5 trebalo bi raditi biopsiju.
