Gray-scale and color Doppler sonographic features of complex XXXX of the breast.

@entity1 @entity24344 @entity5 @entity1557
PURPOSE: To investigate gray-scale and color Doppler sonographic (US) features of @entity1557 ( @entity1557 ), according to the Breast Imaging-Reporting and Data System (BI-RADS) lexicon. METHODS: From 2010 through 2013, 586 @entity1 with @entity24344 were seen; 101 (17%) of those lesions were diagnosed as complex @entity24344 on percutaneous needle biopsy or surgery. Among the @entity1 with complex @entity24344 , 67 who had US examination results available were included in this study. In addition, the results from 98 @entity1 who had simple @entity24344 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 @entity24344 . Color Doppler US examination results were classified according to the amount of vascularity as absent, moderate, or marked. RESULTS: Complex @entity1557 were larger than simple @entity24344 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 @entity24344 (p < 0.05). Multivariate analysis revealed that the @entity5 margin was a predictive factor for complex @entity1557 (odds ratio: 6.08; 95% confidence interval: 1.14-32.49, p < 0.05). On color Doppler US, the complex @entity24344 had higher degrees of vascularity than simple @entity1557 (p < 0.05). CONCLUSIONS: Complex @entity24344 , in comparison with simple @entity24344 , tend to have more aggressive features and to be in higher BI-RADS categories on US examination.
