Is additional imaging necessary for non-enhancing asymmetries on contrast-enhanced mammograms?

Non-enhancing asymmetries on contrast-enhanced mammography

Non-enhancing asymmetries on contrast-enhanced mammography resulting in negative result. Right medio-lateral oblique low-energy (a) and recombined (b) images of a 48-year-old patient show two non-enhancing asymmetries in the central breast. Additional mammographic views and ultrasound were performed, with no malignancy detected on follow-up.

Patients with asymmetries on CEM typically are recalled for additional views, ultrasound and occasionally MRI. But the extra workup might not be necessary.
