Known left breast cancer with positive axillary node. MRI for staging and evaluation of opposite breast. There is heterogeneous amount of fibroglandular tissue in both breasts.Marked parenchymal enhancement is noted bilaterally which is a limitation to this examination.In the left upper central breast, there is segmental enhancement extending from the nipple to the mid-posterior depth, with a 1 cm more mass like enhancement seen posteriorly near the biopsy clip. Overall extent of abnormal enhancement is 9.0 x 2.9 x 3.8 cm, inclusive of the nipple. The pectoralis muscle enhances normally. A subcentimeter intramammary lymph node is seen in the left outer breast.A left axillary lymph node contains clip artifact from the recent biopsy and measures up to 1.6 cm. An additional lymph node with a focally thickened cortical region measures 0.9 cm. No suspicious enhancement is seen in the right breast. No abnormal axillary lymph nodes are identified in the right axillary region.
1. Extensive abnormal enhancement in the left upper central breast measures up to 9 cm AP and includes the nipple. Two abnormal left axillary lymph nodes are present, one containing the biopsy clip. 2. Extreme parenchymal enhancement is a limitation to this exam.
