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

Figure 4

Intracapsular SIGBIC: imaging findings in a 40-year-old woman with left breast stiffening. (a) Breast MRI. The contrast BMRI shows an intracapsular mass with a slight contrast enhancement at coronal and axial images. Yellow arrows correspond to SIGBIC. Blue arrow corresponds to the black-drop signal. (b) One year after the first scan, the patient presented an increase of mass volume and of contrast enhancement. Yellow arrows correspond to SIGBIC. (c) Ultrasound. Intracapsular mass, posterior to the implant, with snowstorm-type aspect (yellow arrows). By elastography, it represents a hard lesion (left image). (d) PET scan. No significant radioisotope uptake by the mass (red circle) is observed. The radiological differential diagnosis is late seroma.
