Posterior acoustic shadowing in benign breast lesions: sonographic-pathologic correlation.
OBJECTIVE
To show a variety of benign breast lesions that exhibit posterior acoustic shadowing on sonography.


METHODS
The cases illustrate a variety of pathologic breast conditions that were collected at a referral breast center at a tertiary medical center.


RESULTS
A variety of pathologic conditions are discussed, with pathologic-imaging correlation.


CONCLUSIONS
Although posterior acoustic shadowing is a sonographic feature that is most commonly associated with mammary malignancies, this sonographic finding may also be seen with benign breast lesions.
