“…The BI-RADS lexicon defined for US findings in masses includes shape, orientation, margin, lesion boundary, echo pattern, and posterior acoustic features. According to the BI-RADS, the management strategy of breast masses classified as BI-RADS category 3 is follow up rather than core needle or surgical biopsy since the likelihood of malignancy is very low (less than 2 %) [3][4][5]. The results of recent studies support this strategy [6][7][8][9].…”

The accuracy of an ultrasound (US) computeraided diagnosis (CAD) system was evaluated for the classification of BI-RADS category 3, probably benign masses. The US database used in this study contained 69 breast masses (21 malignant and 48 benign masses) that at blinded retrospective interpretation were assigned to BI-RADS category 3 by at least one of five radiologists. For computeraided analysis, multiple morphology (shape, orientation, margin, lesions boundary, and posterior acoustic features) and texture (echo patterns) features based on BI-RADS lexicon were implemented, and the binary logistic regression model was used for classification. The receiver operating characteristic curve analysis was used for statistical analysis. The area under the curve (Az) of morphology, texture, and combined features were 0.90, 0.75, and 0.95, respectively. The combined features achieved the best performance and were significantly better than using texture features only (0.95 vs. 0.75, p value=0.0163). The cut-off point at the sensitivity of 86 % (18/21), 95 % (20/21), and 100 % (21/21) achieved the specificity of 90 % (43/48), 73 % (35/48), and 33 % (16/48), respectively. In conclusion, the proposed CAD system has the potential to be used in upgrading malignant masses misclassified as BI-RADS category 3 on US by the radiologists.

“…A solid mass with circumscribed margins, oval shape and horizontal orientation on ultrasound is reasonably categorised as a probably benign finding [1][2][3][4][5][6][7][8][9], especially in conjunction with mammography [10]. In the management of a probably benign breast lesion, short interval follow-up is recommended instead of an immediate biopsy [5] because of the low probability of malignancy, less than 2% [7,10].…”

“…In 2003, ACR developed a BI-RADS ultrasonography lexicon and a category 3 probably benign lesion is defined as a solid mass with oval shape, circumscribed margin, parallel orientation, and no suspicious malignant features [4]. It is not a definite benign designation but is expected to be changed infrequently [15]. …”

Purpose:To evaluate the accuracy of benign core biopsy of probably benign breast lesions (category 3) 2 cm or larger on the basis of excisional biopsy and long-term follow-up. Methods:We retrospectively reviewed 146 category 3 lesions in 146 patients 2 cm or larger which were diagnosed as benign by ultrasound (US)-guided core biopsy. Patients were initially diagnosed as benign at core needle biopsy and then followed up with excisional biopsy (surgical excision, n=91; US-guided vacuum assisted excision, n=35) or breast ultrasonography (n=20). Results:Of the 126 patients who underwent surgical excision or US-guided vacuum-assisted excision, 114 patients were diagnosed with benign lesions, 10 patients with borderline lesions (benign phyllodes tumor), and two patients with malignant phyllodes tumors. The probabilities of lesions being benign, borderline and malignant were 91.8% (134/146), 6.8% (10/146), and 1.4% (2/146), respectively. Of 13 patients who had growing masses on follow-up ultrasonography, three (23.1%) were non-benign (two benign phyllodes tumors and one malignant phyllodes tumor). Conclusion:US-guided core needle biopsy of probably benign breast mass 2 cm or larger was accurate (98.6%) enough to rule out malignancy. But, it was difficult to rule out borderline lesions even when they were diagnosed as benign.
