What is the term for air in the pleural space?

Explanation:
Air in the pleural space is called pneumothorax. The pleural space normally maintains a negative pressure that keeps the lung inflated; when air leaks into that space, the pressure balance is disrupted and the lung can collapse. This distinguishes it from other pleural conditions: chylothorax involves chyle (lymphatic fluid) in the space; hydrothorax is fluid buildup (serous fluid) in the space; pleural effusion is a general term for excess fluid in the pleural cavity.
