氟化铝粉尘致职业性铝尘肺1例报告

A case report of occupational aluminum pneumoconiosis caused by aluminum fluoride dust

目的分析氟化铝粉尘致职业性铝尘肺的临床特点。方法回顾性分析1例因职业接触氟化铝粉尘所致职业性铝尘肺患者的临床资料。结果患者有明确的氟化铝粉尘职业接触史13年;临床症状主要为胸闷、咳嗽及咯痰。高千伏X射线后前位胸片示:两肺纹理增多、模糊;两肺野见多发小点状影,为圆形小阴影q影,分布6个肺区。胸部计算机断层扫描显示:两肺纹理增多,两肺见多发小点状高密度灶。肺功能检查示:小气道通气功能障碍,弥散功能降低。诊断为职业性铝尘肺贰期。结论氟化铝所致职业性铝尘肺发病缓慢,临床症状缺乏特异性,胸部X射线表现以肺纹理增多及圆形小阴影为主。

Objective To analyze the clinical characteristics of occupational aluminum pneumoconiosis caused by aluminum fluoride dust.Methods The clinical data of a case of occupational aluminum pneumoconiosis caused by occupational exposure to aluminum fluoride dust was retrospectively analyzed.Results The patient had a clear history of occupational exposure to aluminum fluoride dust for 13 years.The main clinical symptoms were chest tightness,cough and expectoration.High kV posterior and anterior chest X-ray showed that the texture of both lungs was increased and blurred,and multiple small dot-shaped shadows,including round or q-shaped shadows,were seen in the both lung fields and distributed in 6 lung regions.Chest computed tomography showed that the texture of both lungs increased,and multiple small punctate high density lesions were found in both lungs.The pulmonary function examination showed the small airway ventilation dysfunction and the gas diffusion function was reduced.It was diagnosed as occupational aluminum pneumoconiosis stageⅡ.Conclusion Aluminum fluoride-induced occupational pneumoconiosis has slow onset and lacks specificity in clinical symptoms.The chest X-ray manifestations are mainly increased pulmonary texture and small round shadows.
