From: Contrast-enhanced ultrasound to predict malignant upgrading of atypical ductal hyperplasia
Image of a 38-year-old woman with a nonpalpable mass. a B-mode ultrasound image; b contrast-enhanced ultrasound image showed that the lesion displayed hyper-enhancement with ill-defined enhancement margin and enlarged size on CEUS. The CEUS score was 4 points. This lesion was originally classified as US BI-RADS 4C, upgraded to BI-RADS 5 after CEUS, and both were diagnosed as atypical ductal hyperplasia at US-guided core needle biopsy and at surgery
