Spontaneous pneumothorax

Spontaneous pneumothorax

In medicine (pulmonology), a pneumothorax, or collapsed lung,

is a potential medical emergency caused by accumulation of air or gas

in the pleural cavity. A pneumothorax can occur spontaneously,

or as the result of disease or injury.

What causes a pneumothorax?

Spontaneous pneumothorax is caused by a rupture of a cyst or a small sac (bleb) on the surface of the lung. Pneumothorax may also occur following an injury to the chest wall such as a fractured rib, any penetrating injury (gun shot or stabbing), surgical invasion of the chest, or may be deliberately induced in order to collapse the lung. A pneumothorax can also develop as a result of underlying lung diseases, including cystic fibrosis, chronic obstructive pulmonary disease (COPD), lung cancer, asthma, and infections of the lungs.
