Nonsurgical Management of High-Risk Lesions Diagnosed at Core Needle Biopsy: Can Malignancy Be Ruled Out Safely With Breast MRI?

Abstract

Patients with high-risk lesions associated with the lowest likelihood of malignancy (papilloma and radial scar) and without suspicious MRI findings can safely undergo follow-up instead of surgery. Because of the low negative predictive value, however, MRI is not helpful in cases of lobular neoplasia and atypical ductal hyperplasia, and all these lesions should be excised.
