Objective: To describe the clinical and imaging characteristics of Polyimplant Prosthesis (PIP) hydrogel breast implants.
Methods: Seven patients with surgically confirmed 8 ruptured and 6 normal PIP hydrogel implants were enrolled in our study.We reviewed retrospectively the medical records and breast ultrasonographic and magnetic resonance imaging (MRI) findings of the patients.
Results: Breast asymmetry was the most common clinical feature of PIP hydrogel implant rupture. The main radiologic finding of ruptured implants was a significant fluid collection around the implant. All 4 intracapsular ruptures showed no significant collapse of the implants despite a large accumulation of fluid surrounding the ruptured implants on ultrasonography and MRI. Three extracapsular ruptures showed variable collapse of the implants, partial collapse in 1 implant and total collapse in 2 implants. One extracapsular rupture showed enlargement of the implant. Ultrasonography and MRI revealed hydrogel extension to the muscles and chest wall in all 4 extracapsular ruptures and extensive inflammation and fibrosis in 3 extracapsular ruptures.
Conclusions: Polyimplant Prosthesis hydrogel implant rupture can be clinically silent. Knowledge of clinical and radiologic findings of the ruptured implants will be helpful in its diagnosis.

휴먼영상의학센터에 방문하셔서 검사 받으셨던 하이드로젤 보형물을 갖고 계셨던 일곱분과 서울성모병원 한분의 증례를 모아 논문을 썼습니다.
하이드로젤 보형물은 10년 전 즈음에 우리나라에서 많이 사용되었던 보형물이고
현재는 사용되고 있지 않습니다. 이 보형물이 파열되었을때 겉으로는 표가 잘 안나서 본인이 잘 모를수 있습니다. 영상소견은 비교적 특징적이어서, 초음파 검사를 해보면 잘 알 수 있습니다. 경험적으로 보았을때 피막 밖으로 파열이 동반되었을 때에는 MRI 검사도 해 보면 그 범위 파악이 더 정확합니다.
