Chronic Lymphocytic Leukemia Involving the Breast Parenchyma, Mimicker of Invasive Breast Cancer : Differentiation on Breast MRI

Abstract EN

Leukemic involvement of the breast is rare, particularly involvement by chronic lymphocytic leukemia (CLL).

While concurrent invasive ductal carcinoma and CLL manifesting as a collision tumor in the breast is extremely rare, this association (CLL and carcinoma) has been described in other organs.

We report here a case of a 58-year-old woman with concurrent invasive ductal carcinoma and CLL and describe the imaging features of CLL, particularly the differentiation on MRI.
