Breast Magnetic Resonance (BMR) and Histology Correlation of Silicone-Induced Granuloma of Breast Implant Capsule (SIGBIC)

	Breast Magnetic Resonance	Histology
Extracellular silicone	Restricted to intracapsular space Mass with hypersignal at T2 weighted sequences Black-drop signal Late contrast enhancement	Extracellular and intracellular silicone Predominance of extracellular silicone Germinal centers of lymphocytes Diffuse infiltration by lymphocytes at the fibrous capsule
Intracellular silicone	Same findings from intracapsular Pericapsular edema Lymph node involvement Early contrast enhancement of the extracapsular content Intracapsular collection	Extracellular and intracellular silicone Predominance of intracellular silicone More severe infiltration by lymphocytes at the fibrous capsule Collection with histiocytes and lymphocytes
