A 64-year-old man who had been in the aluminum casting industry for 44 years suffered from dyspnea on exertion. Chest computed tomography revealed honeycomb lung and diffuse ground-glass attenuation mainly in both lower lobes. He was positive for proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA) and respiratory function tests showed marked restrictive ventilatory impairment. Histological findings obtained by thoracoscopic lung biopsy revealed no findings of vasculitis and the deposition of various metal elements, including aluminum, resulted in the diagnosis of aluminum lung. Steroid treatment had poor therapeutic effect. Respiratory failure gradually progressed, and he died five and a half years later. PR3-ANCA remained negative after the introduction of steroids.
