A MG showed local structural distortion in the upper right breast without obvious mass and calcification, ACR BI-RADS 4A. B Ultrasound showed focal heterogeneous hypoechoic area with thickened ductal structure, slightly increased blood flow signal, Adler grade 3, ACR BI-RADS 4C. C ABUS showed hypoechoic mass on the coronal plane with irregular shape, irregular edge and convergence sign. ACR BI-RADS 5. Pathology: Invasive breast cancer (nonspecific type)Back to article page
