Malignant Pathologies (DCIS, IDC, ILC). A) 42-year-old woman presented with new palpable lump. Extensive pleomorphic microcalcifications throughout upper outer breast span at least 8 cm on LE images with non-mass enhancement in region of microcalcifications on RI. Ultrasound performed in this area revealed hypoechoic mass with numerous echogenic foci, subsequently biopsied revealing DCIS. A preoperative MRI revealed a large area of non-mass enhancement in the same distribution. Upon mastectomy, the pathology was upgraded to invasive ductal carcinoma. B 47-year-old woman called back from screening for new mass. Round spiculated 2.1 cm mass in the inferior central breast at posterior depth on LE images demonstrates avid enhancement on RI in addition to demonstrating smaller satellite masses in the upper central breast. After subsequent biopsy and mastectomy, findings on pathology were compatible with multicentric invasive ductal carcinoma. C 44-year-old woman presented with palpable lump in R breast. On CEM, a large high density spiculated mass at 12:00 in the mid breast on LE images is associated with avid enhancement on RI; US confirmed spiculated shadowing mass. MRI showed findings similar to CEM. Final diagnosis: invasive lobular carcinoma with associated LCIS
