Conclusion
Various breast lesions can be observed in CT images,
including inflammatory,
infectious and post procedure findings (scars,
seroma),
as well as malignant lesions such as breast primary (carcinoma,
lymphoma,
sarcoma) and secondary breast or other tumors metastasis.
Irregular and spiculated margins,
irregular shape,
and rim enhancement are the most highly predictive features for malignancy in CT studies (figure 29).
Also washout pattern on postcontrast images and diffuse regional enhancement have high positive predictive value for malignancy.
CT is very sensitive for the detection of coarse calcifications.
When calcifications are identified in the breast at CT,
they are nearly all benign.
It is important for general radiologists to characterize breast lesions incidentally found at CT as benign,
indeterminate,
or sufficiently suspicious to warrant further work-up.
