Of all of the calcifications identified on mammography, fine, linear/branching calcifications are the most suspicious for malignancy, most commonly ductal carcinoma in situ (DCIS). The risk of malignancy associated with fine, linear/branching calcifications is approximately 70%. A recent study evaluating the positive predictive value of suspicious calcifications based on the fifth edition of BI-RADS found the positive predictive value of fine pleomorphic/linear or segmental calcifications was 93.8%. This chapter, which appears in the section on calcifications, reviews the key imaging features, imaging protocols for evaluating calcifications, management, and potential pitfalls or mimics of fine, linear/branching calcifications. Topics discussed will include magnification views, stereotactic core needle biopsy, and radiology–pathology correlation. |
