Chronic Lymphocytic Leukemia Involving the Breast Parenchyma, Mimicker of Invasive Breast Cancer: Differentiation on Breast MRI
Figure 5
Eighteen months later, in the left breast a new distinct irregular 8 mm lesion (black arrow) and a 4 mm focus (arrowhead) were noted. The 8 mm irregular mass has wash-out kinetics (b), (c) for which MR-guided biopsy was recommended; the 4 mm focus does not meet threshold criteria for enhancement. Pathology of the suspicious lesion based on morphology and kinetics was invasive ductal carcinoma on histology. The anterior focus was involvement by CLL.
