From: Contrast-enhanced ultrasound to predict malignant upgrading of atypical ductal hyperplasia
Image of a 60-year-old woman with a palpable mass. a B-mode ultrasound image; b contrast-enhanced ultrasound image showed that the lesion displayed iso-enhancement with the surrounding tissue. The CEUS score was 2 points. This lesion was originally classified as US BI-RADS 4B, downgraded to BI-RADS 4A after CEUS, and diagnosed as atypical ductal hyperplasia via US-guided core needle biopsy and as ductal carcinoma in situ at surgery
