What are common pitfalls in breast imaging interpretation leading to false positives/negatives?

• A. Dense tissue masking lesions.
• B. Relying on a single modality.
• C. Lack of prior comparisons.
• D. All of the above.

Answer: (D)

Understanding pitfalls that can lead to false positives or false negatives in breast imaging is essential. Dense tissue can mask lesions on mammography because both dense tissue and potential masses appear white, reducing contrast and sensitivity; this makes cancers easier to miss and can also cause benign dense patterns to be mistaken for suspicious findings. Relying on a single imaging modality ignores the strengths of other tools—mammography is good for calcifications, ultrasound helps characterize masses and guide biopsies, and MRI adds sensitivity in certain situations—so using only one modality can miss cancers or misinterpret benign changes. Lack of prior comparisons removes a crucial reference point; without earlier images, it’s hard to tell if a finding is new or stable, which can lead to overcalling benign changes as suspicious or missing subtle new cancers. Taken together, these factors drive diagnostic pitfalls, highlighting the importance of multimodality assessment, prior study comparison, and standardized reporting to improve accuracy.
