Ryu AJ, et al. - Medical silicone is widely used as implants and free injections, this study sought to determine the spectrum of complications related to migration or embolization of silicone. Chronic complications related to silicone extravasation and migration can present with local or distant manifestations. These complications were typically encountered many years after the original silicone placement. Magnetic resonance imaging, dual energy CT and ultrasonography are noted to be valuable for non-invasive diagnosis.
