Purpose of the study: To which of the ACR sonographic BIRADS lexicon descriptors can be used reliably to differentiate benign from malignant solid breast masses.
Results: 66% (n=82) of the patients turned out to have benign lesions while 34% (n=43) had malignant breast lesions. All the sonographic BI-RADS descriptor variables demonstrated significant association with the histology results apart from vascularity. The predictive probability of malignancy was lowest (8.36 %) for lesions with parallel orientation and well circumscribed margins and highest (73.89%) for masses with non parallel and poorly circumscribed margins.
Conclusion: There is a significant association between all the sonographic ACR BI-RADS lexicon descriptors and solid breast masses apart from one descriptor: vascularity. Lesions with both non parallel orientation and non circumscribed margins have the highest predictive probability for malignancy.
