Purpose To investigate gray‐scale and color Doppler sonographic (US) features of complex fibroadenoma (FA), according to the Breast Imaging‐Reporting and Data System (BI‐RADS) lexicon. Methods From 2010 through 2013, 586 women with FAs were seen; 101 (17%) of those lesions were diagnosed as complex FAs on percutaneous needle biopsy or surgery. Among the patients with complex FAs, 67 who had US examination results available were included in this study. In addition, the results from 98 women who had simple FAs were included as controls. US features were retrospectively analyzed by two breast radiologists in consensus for shape, margin, echogenicity, posterior acoustic pattern, boundary, orientation, and associated findings. They also reassessed the BI‐RADS category for FAs. Color Doppler US examination results were classified according to the amount of vascularity as absent, moderate, or marked. Results Complex FA were larger than simple FAs were (14.5 cm versus 12.1 cm, p > 0.05). On univariate analysis, a round to irregular shape, an uncircumscribed margin, the presence of associated findings, and BI‐RADS categorization as 4a and 4b were more frequently revealed in complex than in simple FAs ( p < 0.05). Multivariate analysis revealed that the tumor margin was a predictive factor for complex FA (odds ratio: 6.08; 95% confidence interval: 1.14–32.49, p < 0.05). On color Doppler US, the complex FAs had higher degrees of vascularity than simple FA ( p < 0.05). Conclusions Complex FAs, in comparison with simple FAs, tend to have more aggressive features and to be in higher BI‐RADS categories on US examination. © 2015 Wiley Periodicals, Inc.
