AJR Am J Roentgenol. 2007 Dec;189(6):1402-6. doi: 10.2214/AJR.07.2402.


Objective: The purpose of this study was to evaluate the high-resolution CT findings of silicoproteinosis.

Conclusion: Silicoproteinosis usually manifests as bilateral consolidation in the posterior portions of the lungs and as numerous centrilobular nodules. Calcification within areas of consolidation is a common finding.
