Pleural Effusion as a Potential Complication of Foreign Body Reaction to Silicone Breast Implants: A Case Study.

Breast augmentation surgery, like any other surgery, has potential complications, including the less common complication of pleural effusion. We present a unique case of a 44-year-old female who developed pleuritic chest pain and shortness of breath 10 days after her breast augmentation surgery, with no prior history of cardiac or autoimmune conditions. The temporal relationship between the surgery and the onset of symptoms suggested a possible direct link to the implants. Imaging showed a small- to moderate-sized left pleural effusion, and pleural fluid analysis revealed findings suggestive of a foreign body reaction (FBR), including evidence of mesothelial and inflammatory cells with a lymphocyte percentage of 44% and monocytes of 30%. The patient received intravenous steroids at a dose of 40 mg every eight hours for three days while hospitalized, followed by a tapered oral dose of steroids upon discharge, for over three weeks. Follow-up imaging studies showed complete resolution of the pleural effusion. The diagnosis of pleural effusion resulting from FBR to silicone gel-filled breast implants involves a clinical history, cytopathological examination, and the exclusion of other potential causes. This case highlights the importance of considering FBR as a potential cause of pleural effusion post-breast augmentation surgery.
