Figure 2b: Multifocal ILC in the upper outer quadrant of the right breast and negative findings in contralateral breast at conventional mammography and US in a 54-year-old woman. (a) Craniocaudal and (b) mediolateral conventional mammograms show presence of three parenchymal distortions (arrows) in the upper outer quadrant of the right breast. (c) Transverse maximum intensity projection reconstruction of contrast-enhanced T1-weighted GRE MR image (8.1/4; flip angle, 30°) shows presence of three suspicious lesions (arrows) suggestive of multifocal lesions in the upper outer quadrant of the right breast. No lesions were evident at contrast-enhanced MR mammography of the contralateral left breast. This finding was confirmed at follow-up conventional mammography, US, and contrast-enhanced MR mammography.
