Uncommon occupational lung diseases: high-resolution CT findings.

OBJECTIVE

The purpose of this article is to describe the high-resolution CT (HRCT) features of uncommon occupational lung diseases.

CONCLUSION

HRCT plays an increasing role in the evaluation of occupational lung diseases. We present several cases of unusual occupational lung diseases and their HRCT findings. The diseases studied were siderosis, talcosis, berylliosis, calcicosis, hypersensitivity pneumonitis (due to wheat flour and isocyanates), and Ardystil syndrome. The characteristic HRCT findings together with clinical features and related occupational history improve the diagnostic accuracy of these diseases.
