Figure 4d.

Cancer seen on only the CC DBT view in a 49-year-old woman at routine screening. (a, b) CC DBT image (a) and same view with magnification (b) show an area of architectural distortion (arrow in a) with faint calcifications that was seen only in the lateral breast on the CC DBT view only. (c) MLO DBT image fails to show a definite correlative area of distortion (?). (d) CC DM image shows no evidence of distortion. No corresponding lesions were identified at US. Biopsy revealed intermediate-grade invasive ductal carcinoma associated with ductal carcinoma in situ. Subtle findings seen on only one view at DBT, particularly architectural distortion, should be aggressively pursued because some cancers are not always evident on both CC and MLO views.
