60-year-old with personal history of right breast cancer and now known to have BRCA gene mutation. Patient desires prophylactic mastectomy. There is heterogeneous amount of fibroglandular tissue in the left breast. Mild parenchymal enhancement is noted in the left breast. The patient is status post right mastectomy and reconstruction. No suspicious enhancement in the right chest wall.There is a 6 mm reniform enhancing mass in the left lower outer quadrant anterior depth. This is probably an intramammary lymph node. No other enhancing masses or areas of non-mass enhancement are seen. No abnormal axillary lymph nodes are identified in either axillary region. Postoperative changes are identified in the right axilla.
A 6 mm left breast mass is probably a normal intramammary lymph node, though establishing stability by comparing to prior examinations is recommended. If stability cannot be established, then targeted ultrasound should be performed to ensure that this has the sonographic appearance of a lymph node as well.BIRADS: 0 - INCOMPLETE; Need additional imaging evaluationRECOMMENDATION: O - Old Study For Comparison.
