Conclusion
DCIS is a heterogeneous disease process that can have a variable appearance.
The most frequnte presentation are the pleomorphyc microcalcifications with ductal distribution.
A hypoechoic mass with non-circumscribed margins,
parallel orientation,
and normal acoustic transmission is the most common US finding in DCIS.
In the setting of calcified DCIS,
US is helpful in evaluating for a possible invasive component and in guiding biopsy.
Noncalcified DCIS may be identified in the evaluation of a mammographic mass or asymmetry,
in symptomatic patients,
at high-risk screening US,
or in the evaluation of disease extent.
MR imaging can allow improved presurgical planning as well as depict contralateral,
multifocal,
and multicentric disease.
