Pneumoconiosis is a lung disease that develops as a result of a tissue reaction that occurs with the accumulation of inorganic particles. Pathoclinical features may vary depending on the type of inhaled particle. Today, fibrotic and nonfibrotic tissue reactions are well defined in some substances. For example, it is known that exposures such as silica, asbestos, beryllium, and talc are associated with fibrosis in the lung, while exposures such as iron, tin, and barium sulfate cause non-fibrogenic changes. However, the pathoclinic and radiological findings of some rare exposures such as zirconium are not widely known. In a 52-year-old dental technician with a 26-year history of zirconium exposure, more prominent parenchymal emphysematous and fibrotic changes were detected in the upper zones of the thorax high-resolution computed tomography. Since zirconium exposure was clearly defined, radiological findings of this case may be useful to current literature.
尘肺病是一种由于无机颗粒积聚引发组织反应而导致的肺部疾病。其病理临床特征可能因吸入颗粒的类型而异。如今，某些物质中的纤维化和非纤维化组织反应已得到明确界定。例如，已知接触二氧化硅、石棉、铍和滑石等物质会导致肺部纤维化，而接触铁、锡和硫酸钡等物质则会引起非纤维化改变。然而，诸如锆等一些罕见接触情况的病理临床和放射学表现并不广为人知。在一名有26年锆接触史的52岁牙科技术员中，胸部高分辨率计算机断层扫描显示胸部上区出现更明显的实质性肺气肿和纤维化改变。由于锆接触情况明确，该病例的放射学表现可能对当前文献有用。
