If air enters the pleural space either by a hole in the lung or the chest wall, the pressure in the pleural space equals the pressure outside the body. Thus, the vacuum is lost and the lung collapses. Spontaneous pneumothorax is caused by a rupture of a cyst or a small sac (bleb) on the surface of the lung.
