Which calcification pattern on mammography is typically benign?

• A. Popcorn calcifications
• B. Pleomorphic calcifications
• C. Fine linear/branching calcifications
• D. Clustered calcifications

Answer: (A)

Popcorn calcifications are a sign of a long-standing benign process, most often a fibroadenoma. They appear as large, coarse, round to oval calcifications with a smooth, well-defined border and are usually confined to a single lesion. Their chunky, “popcorn-like” appearance and stability on serial imaging reflect calcification within a benign nodule rather than the fine, irregular patterns seen with malignancy. Because they tend to stay the same over time, this pattern is reliably reassuring. In contrast, pleomorphic calcifications are irregular in shape and size and can be associated with ductal carcinoma in situ or cancer; fine linear or branching calcifications follow ducts and raise concern for DCIS; clustered calcifications can indicate an abnormal process requiring closer evaluation. The benign popcorn pattern stands out because of its coarse, large, rounded form and benign behavior on follow-up.
