The management of atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS), together known as lobular neoplasia (LN), as the most significant lesion on core biopsy remains controversial in spite of a relatively large number of publications dealing with the topic.

Proliferative lesions with atypia include fat atypia, atypical ductal hyperplasia (ADH) and lobular neoplasia (atypical lobular hyperplasia (ALH), lobular carcinoma in situ) (12).

The remaining 82% (146 of 177) of MRI-guided biopsies were nonmalignant, of which 71% (126 of 177) revealed benign changes (or no pathologic findings) and 11% (20 of 177) showed epithelial atypia, which includes 17 cases of lobular neoplasia and 3 cases of atypical ductal hyperplasia.
