Pulmonary cavity

Pulmonary cavities are gas-filled areas of the lung in the center of a nodule, mass or area of consolidation. They are usually evident on plain radiography and CT. They are typically thick walled and their walls must be greater than 2-5 mm. They may be filled with air as well as fluid and may also demonstrate air-fluid levels.

According to the Fleischner society pulmonary cavities are defined "gas-filled space, seen as a lucency or low-attenuation area, within pulmonary consolidation, a mass, or a nodule" 7.

The cause of pulmonary cavities is broad. They may develop as a chronic complication of a pulmonary cyst, or secondary to cystic degeneration of a pulmonary mass. They may enlarge or involute over time.

Causes

Pulmonary cavities may be the result of malignancy, infection, inflammation or be congenital:
