Pneumothorax is air within the potential space between the parietal pleura and visceral pleura leading to a partial or complete collapse of the lung.
General
- Clinical diagnosis (typically by radiology) or autopsy diagnosis.
Causes
- Primary.[1]
- No underlying cause.
- Secondary - underlying disease.
- Emphysema.
- Bullous disease.
- Blunt force trauma - esp. rib fractures.
- Interstitial lung disease.[citation needed]
- Iatrogenic.
- Lymphangioleiomyomatosis.
- Birt–Hogg–Dubé syndrome.[2]

Comment:
The wedge-shaped pattern of fibrotic healing seen in the pleura is typical
of spontaneous pneumothorax.

Comment: The wedge-shaped pattern of fibrotic healing seen in the pleura is typical of spontaneous pneumothorax. The emphysema present may be a contributory factor; however, other causes must be excluded clinically.
