Interactive case review of radiologic and pathologic findings from breast biopsy: are they concordant? How do I manage the results?

Abstract

The number of imaging-guided percutaneous breast biopsies performed has steadily increased as imaging techniques have improved. Percutaneous biopsy is becoming more commonplace and supplanting excisional biopsy as the preferred diagnostic tool. The radiologist's role in caring for patients who undergo breast biopsy extends beyond imaging to identifying lesions for biopsy and then performing the procedure. Radiologists must also be cognizant of radiologic-pathologic correlation to determine whether biopsy results are concordant with imaging findings and make management recommendations. Management of microcalcifications, masses, and areas of asymmetry begins with recognizing and characterizing the findings with the proper Breast Imaging Reporting and Data System (BI-RADS) lexicon. Determining concordance between imaging findings and histologic results is equally important. The decision to recommend surgical excision or short-term follow-up relies heavily on whether the histologic diagnosis correlates with the imaging findings, a determination that is part of the radiologist's responsibilities if he or she performs the biopsy.
