36-year-old with triple positive breast cancer status post systemic therapy. There is extreme amount of fibroglandular tissue in both breasts.Minimal parenchymal enhancement is noted bilaterally. High T2 signal fluid is noted in bilateral retroareolar ducts. RIGHT BREAST: Interval decrease in degree of enhancement and extent of enhancement of the segmental nonmass enhancement in the central lateral right breast, which now enhances only as a few scattered enhancing foci. On the current exam, these extend over 4.7 x 2.1 x 4.3 cm previously 6.9 x 3.3 x 5.3 cm (on 3/10/15), originally 9.3 x 6.6 x 5.3 cm. No new areas of abnormal enhancement. A few medial foci of enhancement are again seen. Please refer to mammograms regarding extent of calcifications. In the right axilla, there is a lymph node with normal morphology. No abnormal lymph nodes.LEFT BREAST: The previously seen retroareolar lobulated rim enhancing mass with nipple involvement appears only as faint non-mass enhancement, currently measuring 0.6 x 0.6 cm previously 1.1 x 1.2 x 1.2 cm (on 3/10/15), originally 2.9 x 2.0 x 2.8 cm. Interval decrease in size and degree of enhancement of 6 o'clock position far posterior depth previously seen spiculated heterogeneously enhancing mass which extended near the fascia overlying the pectoralis muscle. Faint residual linear enhancement now measures 2.7 cm AP previously 3.2 x 2.8 x 1.7 cm (on 3/10/15), originally 5.6 x 3.7 x 2.7 cm.Nonenhancing biopsy proven 1.3 cm fibroadenoma in 1:30 position, mid depth is unchanged. Previously seen enhancing 1.2 cm rounded mass in the 2 o'clock position, posterior depth does not demonstrate enhancement on the current examination, although remains visualized on T2 sequence. No abnormal lymph nodes are seen in the left axilla.
Near complete resolution of abnormal enhancement in each breast. Please refer to the mammogram report regarding extent of bilateral calcifications. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
