In patients with silicone breast implants, implant rupture can occur, which can be intra- or extracapsular. Following implant rupture, silicone can travel through the lymphatic system into regional and distant lymph nodes. The purpose of this pictorial essay is to present findings of silicone implant rupture with intramammary and systemic silicone deposition as seen on dual energy CT, ultrasound, mammogram, PET/CT and MRI. We include imaging findings of silicone deposition in the breast in cases of intra- and extracapsular rupture. We also present silicone deposition in mediastinal, axillary, and internal mammary lymph nodes, as well as in the liver and spleen. To our knowledge, deposition of silicone in the liver and spleen has not been previously demonstrated on cross-sectional imaging. While all imaging modalities were able to detect silicone in the spleen, ultrasound appeared to be more sensitive than dual energy CT or MRI for detection of silicone deposition in the liver.
在接受硅胶乳房植入物的患者中，植入物可能会发生破裂，破裂可能发生在包膜内或包膜外。植入物破裂后，硅胶可通过淋巴系统进入局部和远处淋巴结。本文的目的是展示双能CT、超声、乳房X线摄影、PET/CT和MRI所见的硅胶植入物破裂伴乳房内和全身硅胶沉积的情况。我们纳入了包膜内和包膜外破裂病例中乳房内硅胶沉积的影像学表现。我们还展示了纵隔、腋窝和乳内淋巴结以及肝脏和脾脏中的硅胶沉积。据我们所知，此前横断面成像尚未证实硅胶在肝脏和脾脏中的沉积。虽然所有成像方式都能够检测到脾脏中的硅胶，但超声在检测肝脏中的硅胶沉积方面似乎比双能CT或MRI更敏感。
