What can be helpful when evaluating non visualized posterior margin?

• A. Fremitus
• B. Posterior acoustic shadowing
• C. Calcifications
• D. Ductal dilation

Answer: (A)

When a lesion’s posterior edge isn’t visible on ultrasound due to attenuation, using tissue fremitus can help reveal the boundary. Fremitus involves observing how vibrations or small tissue motions propagate through the breast. By applying gentle compression or dynamic scanning to evoke these vibrations, the interface between the lesion and surrounding tissue alters the transmission in a way that makes the posterior margin easier to see. This approach can clarify whether the edge is truly missing because of artifact or if the lesion has a definite posterior boundary. Posterior acoustic shadowing tends to obscure details behind a lesion and isn’t a method to reveal a hidden margin, even though it provides information about tissue attenuation. Calcifications show up as bright echoes but don’t help delineate the posterior edge of a lesion. Ductal dilation points to ductal pathology rather than informing posterior margin visualization.
