Pulmonary aluminosis diagnosed with in-air microparticle induced X-ray emission analysis of particles

Abstract

We herein present a case of pulmonary aluminosis diagnosed with in-air microparticle induced X-ray emission (in-air micro-PIXE) analysis. The diagnosis of pulmonary aluminosis was supported by the occupational exposure to aluminum, ground glass opacity and ill-defined centrilobular nodular opacities seen in high resolution CT, and respiratory bronchioles accompanied by pigmented dust by histological examination by in-air micro-PIXE analysis of the lung tissues. The possibility of developing this rare condition should not be underestimated in workers at high-risk jobs. This is an important report showing the usefulness of an in-air micro-PIXE analysis for the early diagnosis of aluminosis.
