Spontaneous pneumothorax

• Overview
• Symptoms
• Treatment
• Prevention

Definition:

Spontaneous pneumothorax is a collection of air or gas in the chest that causes the lung to collapse. Spontaneous means there is no traumatic injury to the chest or lung.

See also: Pneumothorax

Alternative Names:

Lung collapse - spontaneous

Causes, incidence, and risk factors:

There are two types of spontaneous pneumothorax:

• Primary spontaneous pneumothorax
• Secondary spontaneous pneumothorax

Primary spontaneous pneumothorax occurs in people without lung disease. It usually occurs in tall, thin men between the ages of 20 and 40. Usually, the rupture of a small air- or fluid-filled sac in the lung (called a bulla ) causes a primary spontaneous pneumothorax.

Secondary spontaneous pneumothorax most often occurs with chronic obstructive pulmonary disease (COPD). Other lung diseases commonly associated with spontaneous pneumothorax include:

• Tuberculosis
• Pneumonia
• Asthma
• Cystic fibrosis
• Lung cancer
• Interstitial lung disease
