A Case of a Giant Siliconoma Mimicking Localized Breast Cancer

Abstract

Silicone gel–filled breast implants are widely used for breast augmentation and reconstruction after mastectomy. However, there are some known complications associated with silicone implants: Leakage and migration of silicone particles from the implant cause a granulomatous reaction. Granulomas may present as masses with features of malignancy on breast MRI. We present a case of a giant breast siliconoma in a woman who had undergone reconstruction with breast prostheses, which were surgically removed because of rupture 8 years ago.
