MRI of a complicated case of IDC with lactation changes. Axial subtracted DCE-MRI and CAD of lactating patient with newly diagnosed PABC, undergoing preoperative evaluation are shown. The tumor, 2.8 cm IDC in the left breast, is well visible on top of the surrounding BPE (a). Yet, additional ipsi-lateral enhancing 0.9 cm lesion is apparent (b). Upon focused US and US-guided biopsy, the second lesion came up to be adenosis and lactating changes on pathology. Interestingly, CAD depicted both lesions, as well as slight BPE in blue color, which corresponds to persistence wash-in pattern which usually represents a benign pattern (c)
