Concordant or discordant? Imaging-pathology correlation in a sonography-guided core needle biopsy of a breast lesion

An imaging-guided core needle biopsy has been proven to be reliable and accurate for the diagnosis of both benign and malignant diseases of the breast, and has replaced surgical biopsy. However, the possibility of a false-negative biopsy still remains. Imaging-pathology correlation is of critical importance in imaging-guided breast biopsies to detect such a possible sampling error and avoid a delay in diagnosis. We will review fi ve possible categories and corresponding management after performing an imaging-pathology correlation in a sonography-guided core needle biopsy of a breast lesion, as well as illustrate the selected images for each category in conjunction with the pathologic fi nding. Radiologists should be familiar with the imaging features of various breast pathologies and be able to appropriately correlate imaging fi ndings with pathologic results after a core needle biopsy.
