What can be helpful when evaluating ill defined borders?

• A. Fremitus
• B. Clear margins
• C. Calcifications
• D. Shadowing

Answer: (A)

Fremitus is about feeling tissue vibrations transmitted through the breast. When borders around a lesion are ill defined on imaging, using a tactile or vibrational cue helps reveal where one tissue type ends and another begins. By palpating or applying gentle vibration, the way vibrations travel changes at the edge of a mass, making the boundary more apparent than it appears on static images. This bedside cue can guide more focused imaging or sampling. Clear margins aren’t present when borders are ill defined, so the technique adds value specifically when margins aren’t obvious. Calcifications show internal features, not the border between lesion and normal tissue. Shadowing can obscure or distort margins, not reliably clarify them.
