Lobular lesions of the breast: Imaging findings of lobular neoplasia and invasive lobular carcinoma

The clinical and radiological diagnoses of lobular neoplasia (LN) and invasive lobular carcinoma (ILC) are difficult because they have no specific findings. The purpose of this study is to illustrate the imaging and pathological features of LN and ILC. For lobular lesions, imaging is the basic and essential diagnostic tool, so the understanding and effective use of multimodality imaging findings are important. This article shows imaging findings of LN, which are seldom known, and ILC as well as their characteristic histopathological features.
