Vanishing Lung Syndrome
General Considerations
- Uncommon disorder
- Characterized by very large bullae
- Bullae are air-filled, thin-walled (<1mm) spaces in the lung resulting from destruction of alveolar tissue
- In vanishing lung syndrome the bulla takes up more than a third of the occupied lung
- Paraseptal emphysema and subpleural bullae are seen in virtually all patients
- Most also have separate centrilobular emphysema
- Most common in young men, mostly in smokers
