The authors describe a patient who presented with acute onset of a lower back fluctuant mass 12 years after breast reconstruction with a latissimus dorsi musculocutaneous flap and silicone gel implant. Aspiration and subsequent surgical exploration revealed this mass to be free-flowing silicone gel within a cavity that was confluent with the breast implant capsule through an axillary tunnel. Excision of the back cavity, explantation with subtotal capsulectomy, and implant replacement resolved the problem. Although distant migration of extracapsular silicone gel from the breast to the axilla, arm, abdomen, and groin has been described, the authors think this represents the first reported case of distant migration of silicone gel to the lower back.
作者描述了一名患者，该患者在采用背阔肌肌皮瓣和硅胶植入物进行乳房重建12年后，出现了急性发作的下背部波动性肿块。抽吸及随后的手术探查显示，该肿块为一腔隙内的可自由流动的硅胶，该腔隙通过一条腋窝通道与乳房植入物包膜相连。切除背部腔隙、行部分包膜切除术并取出植入物，然后更换植入物，解决了该问题。尽管已有关于乳房外硅胶从乳房向腋窝、手臂、腹部和腹股沟远处迁移的报道，但作者认为这是首例报道的硅胶向背部下方远处迁移的病例。
