From: Contrast-enhanced ultrasound to predict malignant upgrading of atypical ductal hyperplasia
Image of a 42-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, enlarged size on CEUS, and penetrating vessels. The CEUS score was 5 points. This lesion was originally classified as US BI-RADS 4A, upgraded to BI-RADS 4B after CEUS, and diagnosed as atypical ductal hyperplasia via US-guided core needle biopsy and as ductal carcinoma in situ at surgery
