A 29-year-old female with ferumoxytol injection before breast magnetic resonance imaging. (a) Axial precontrast image demonstrating apparent enhancement in the heart and vasculature (arrowheads) and nonmass enhancement in the left breast (arrow). (b) Axial postcontrast image demonstrating similar enhancement in the heart and vasculature (arrowheads) and nonmass enhancement in the left breast (arrow).

There was apparent gadolinium-based contrast enhancement on precontrast imaging acquisitions [Figure 1a]. No significant increase in enhancement was noted following gadolinium administration [Figures 1b and 2]. Areas of apparent nonmass enhancement on the MRIs [Figure 1a and b] were biopsied at the request of the patient and demonstrated benign pathology.
A 29-year-old female with ferumoxytol injection before breast magnetic resonance imaging. Subtraction image is extremely limited with no significant contrast noted in the heart and vasculature (arrowheads). Minimal nonmass enhancement is noted in the left breast (arrow).
