Free silicone injection. High signal collections (black arrows) are noted at the retroglandular regions of both breasts on these axial MR images of silicone-only sequence (a–c), compatible with free silicone. Collections are also seen in premammary fat (white arrowheads), retropectoral region (white arrows), and pre-sternal region (black arrowheads). They are suppressed on silicone-saturated sequence (d, e). No enhancement is noted over the pre-sternal collection (black arrowheads) on T1-weighted post-contrast image with subtraction (f)
