 | Media file 1: Inversion recovery magnetic resonance image shows an intact silicone gel breast implant. |
 | Media file 2: An intact silicone gel breast implant with a valve appears as a low–signal-intensity region in the retroareolar area. Most silicone implants are valveless; this implant includes a port for addition of saline by the implanting surgeon, for custom-fit sizing. No saline was added to this implant. |
 | Media file 3: Magnetic resonance image shows a normal radial fold, which appears as a low–signal-intensity line through the implant. |
 | Media file 4: Fast spin-echo T2-weighted magnetic resonance image shows the keyhole sign. Silicone appears on both sides of the radial fold. The differential diagnosis includes intracapsular rupture and extensive gel bleeding. A small water droplet is in the posterior aspect; small water droplets have no prognostic importance in silicone gel breast implant rupture. |
 | Media file 5: Magnetic resonance image shows the keyhole, or inverted teardrop, sign. The linguine sign is present elsewhere on the image, and a portion of the sign is adjacent to the keyhole sign. These findings are consistent with an intracapsular silicone gel breast implant rupture. |
 | Media file 6: Craniocaudal mammogram shows free extracapsular silicone around a ruptured silicone gel breast implant. |
 | Media file 7: Mediolateral oblique mammogram shows extracapsular silicone. Note the opaque axillary lymph node, which is consistent with nodal uptake of silicone. |
 | Media file 8: Sagittal magnetic resonance image shows extracapsular silicone, with a high–signal-intensity lesion in axilla (which is compatible with silicone in node, as shown on the mammogram) (see Image 7). |
 | Media file 9: Longitudinal ultrasonogram shows the snowstorm, or hyperechoic, noise associated with the capsule in proven extracapsular silicone gel breast implant rupture. Usually, the interior of an intact implant is sonolucent. |
 | Media file 10: Longitudinal ultrasonogram shows the snowstorm appearance of the soft tissues of the breast, which is consistent with extracapsular silicone gel breast implant rupture and free parenchymal silicone. |
