pneumothoraces in Science
pneumothorax
  (n'mō-thôr'āks')   
Accumulation of a gas, such as air, in the space between the pleurae of the lungs and the pleurae lining the chest wall (called the pleural cavity), occurring as a result of disease or injury or induced to collapse the lung in the treatment of tuberculosis and other lung diseases. A large pneumothorax is treated by inserting a syringe or a tube into the pleural cavity to aspirate air, which helps the collapsed lung to expand.
