Ms. Faith is a 50 year old female with recently diagnosed right breast malignancy. She presents for MRI for further evaluation. There is heterogeneous amount of fibroglandular tissue in both breasts. Marked background parenchymal enhancement is noted bilaterally, which limits the sensitivity of this examination.In the right upper outer breast, there is an irregular enhancing lesion identified measuring 2.0 x 1.4 x 2.2 cm (AP x ML x SI). Susceptibility artifact from biopsy marker clip is seen centrally within this lesion, compatible with biopsy proven malignancy. There is no additional abnormal enhancement present in the right breast. There is no abnormal enhancement present in the left breast. Of note, there are several non-dilated, non-enhancing retroareolar ducts with fluid identified in the left breast. No abnormal axillary lymph nodes are identified in either axillary region.
