Anterior to this are smaller areas of clumped non-mass enhancement extending close to the nipple (within at least 4 mm). Total AP extent inclusive of the biopsy site and the anterior non-mass enhancement is 4.0 cm. There is additional enhancement along the lateral aspect of the left nipple that is non-specific. Multiple artifacts from the patient's surgical clips are seen posterior to these areas of enhancement. No abnormal enhancement is seen in the right breast.
