Silicone-Induced Granuloma of Breast Implant Capsule (SIGBIC): Histopathology and Radiological Correlation

Figure 6

SIGBIC with extracapsular extension. 52-year-old woman with left breast stiffening. (a) T2-weighted BMRI shows an intracapsular hypersignal mass posterior to the implant (left image). After contrast, there is small enhancement of the mass (right image). (b) One year after the first scan, the patient presented an increase of mass volume and of contrast enhancement. Yellow arrows correspond to SIGBIC. Diffuse thickening of the fibrous capsule is also observed. (c) Ultrasound. Doppler scan shows an increase in vascularization at the periphery of the implant, where an intracapsular mass is observed, determining a snowstorm-type appearance. There are also changes of the inner implant echotexture. (d) PET scan. Radioisotope uptake by the mass (green circle). There is also uptake at the ticked fibrous capsule. The radiological differential diagnosis are late seroma, infectious disease, and BIA-ALCL.
