Overview
- A chest radiograph is obtained in virtually all patients undergoing evaluation for silicosis. It will confirm the presence of nodules in the lungs, especially in the upper lobes.
Chest X Ray
- In acute silicosis, the chest radiograph demonstrates characteristic
- Bilateral consolidation,
- Typically symmetrical
- Diffuse ground glass opacities which may be perihilar or basilar [1][2].
- These features may progress from a pattern of lower zone opacities to large masses of coalesced parenchymal tissue in the mid and lower zones, which are typically bilateral but not always symmetrical [1].
- The typical chest radiograph finding in chronic simple silicosis is the presence of many small round opacities of
- Less than 10 mm in diameter,
- Distributed predominantly in the upper lung zones.
- Progressive massive fibrosis also known as conglomerate silicosis occurs when these small opacities gradually enlarge and coalesce to form larger opacities
- Of more than 10 mm in diameter .
- Asymmetrical, and may mimic a neoplastic process.
- And associated with upper lobe fibrosis and lower lobe hyperinflation.
- Hilar adenopathy with prominent eggshell calcification[3] is present in up to 5 percent of workers with silicosis.
- Cavitation may also be present in advanced disease or in the setting of mycobacterial superinfection.
