We report a case in which the polyurethane foam coating of a MEME mammary prosthesis disintegrated after 10 years in situ. Unusual in this patient was complete disappearance of the silicone shell. MRI findings were consistent with implant rupture, but this imaging procedure did not accurately predict absence of the silicone shell as well. The fate of silicone under these circumstances is unknown, but the interaction of chemical byproducts of polyurethane degradation and local tissue factors may be contributory.
