Evaluation of Features in Probably Benign and Malignant Nonmass Enhancement in Breast MRI

Figure 2

(a) Axial- and coronal-subtracted contrast-enhanced breast (A, B) MRI images in a 46-year-old female show clustered ring nonmass (dashed circle) enhancement with segmental distribution in the left breast. The cluster ring internal enhancement pattern is better visible in the inset photo. The biopsy result was invasive ductal carcinoma. (b) (A) MLO and (B) CC views of the same patient show segmental pleomorphic microcalcifications (dashed circle). (C) Targeted ultrasound demonstrates a nonmass lesion with tubular structures and architectural distortion.
