Granulomatous pneumonitis following exposure to the World Trade Center collapse.

摘要: We describe a 37-year-old male engineer who presented with cough and dyspnea 3 weeks after exposure to dust resulting from the collapse of World Trade Center (WTC). Radiographs chest high-resolution CT demonstrated diffuse miliary nodularity. Lung biopsy specimens confirmed presence diffuse, noncaseating granulomatous nodules. Scanning electron microscopy energy-dispersive radiograph analysis revealed large quantities silicates. Cellular immunologic studies showed normal response beryllium, results Kveim testing were negative. suspect that one or more materials WTC catastrophe may be implicated in development pulmonary disease.
