Atypical rupture of a Poly Implant Prothese implant and fluid shifting: a case report

Abstract

Women have undergone augmentation mammoplasty for decades, and if implant rupture is suspected, imaging modalities such as magnetic resonance imaging (MRI) and ultrasonography are available. The linguine sign, keyhole sign, and noose sign are all suggestive of rupture. However, earlier-generation implants with alternative filler materials demonstrate rupture signs that differ from those of today’s better-known implant materials. A 60-year-old female patient who had undergone augmentation mammoplasty 20 years ago presented with left breast swelling and pain in the lower-outer quadrant. Ultrasonography and MRI confirmed extracapsular diffuse wall enhancement with suspected, but not apparent, discontinuity in the patient’s left breast implant. Therefore, both implants were removed. It was determined that these were Poly Implant Prothése implants. The left breast implant differed from the contralateral implant in that it contained fluctuating fluid. This could be attributed to an osmotic gradient that caused the implant to swell and weakened the elastomer shell, resulting in micro rupture without a gross tear. Patients who undergo augmentation mammoplasty should have regular follow-up examinations, even if there are no symptoms. Furthermore, clinicians should be aware that some patients who have had breast augmentation mammoplasty may experience atypical symptoms and signs if the implant ruptures.
