[3] The most common cause of a single lung cavity is lung cancer. [4]
Each lung is enveloped by a serous membranes called pleurae, which also overlays the inside surface of the rib cage; the two membranes (called the visceral and parietal pleurae, respectively) form an enclosing sac known as the pleural cavity, which contains a lubricating film of serous fluid (pleural fluid) that separates the two pleurae and ...
