초록
We present a 53-year-old woman with a large chest wall mass in the interpectoralspace, which was eventually confirmed as a lipogranuloma resulting from hydrogelimplant rupture. Ultrasonography (US) showed reduced implant volume withsurrounding peri-implant fluid collection, suggesting the possibility of implantrupture. A heterogeneously hypoechoic mass was found between the pectoralis majorand minor muscles adjacent to the ruptured implant. On magnetic resonance imaging(MRI), there was a large mass in the left interpectoral space of the upper inner chestwall. The mass showed slightly high signal intensity (SI) on pre-contrast T1-weightedimage (WI) with mixed iso and high SI on T2-WI. The signal of the mass wassuppressed using the water suppression technique but not with the fat suppressiontechnique on T2-WI. The mass showed diffuse enhancement upon contrastenhancement. The enhancing kinetics showed persistent enhancement pattern. US-guided core needle biopsy revealed a lipogranuloma and removal confirmed aruptured PIP hydrogel implant.
