Figure 1. Photographic magnification of the subareolar region on a standard left craniocaudal mammogram shows dilated ducts. The arrow suggests ductal cutoff.
Figure 2. Transverse sonograms obtained with a 7.5-MHz linear transducer in the subareolar region. The straight arrows show a dilated tubular structure. The curved arrow indicates an intraluminal solid mass. NIP refers to the location of the inverted nipple.
