CXR Case 054

There are multiple small calcified parenchymal densities projecting over both lung fields.
* The lungs are otherwise clear.

A common cause for small calcified lung opacities is healed varicella pneumonia.
These lesions are usually 2-3mm in size, and are randomly scattered throughout the lungs.

A differential for small nodules in the lungs includes chronic exposures in occupation-specific conditions such as silicosis and coal worker’s pneumoconiosis.
