Ms. Swift is a 47-year-old female with newly diagnosed left breast cancer, solely detected on ultrasound. There is heterogeneous amount of fibroglandular tissue in both breasts.There is extensive bilateral, symmetric background parenchymal enhancement identified. Although marked in nature, there is no one focus that is more suspicious than the rest. There are multiple T2 hyperintense non-enhancing cysts identified bilaterally. Susceptibility artifact from biopsy marker clip is identified in the left lower inner breast with faint surrounding enhancement, measuring approximately 0.5 x 0.5 x 0.6 cm, compatible with biopsy-proven malignancy. There is no additional abnormal enhancement seen in either breast. No abnormal axillary lymph nodes are identified in either axillary region.
