About Empyema vs pleural effusion

Empyema vs pleural effusion are both conditions affecting the pleural space in the chest, but they differ in their nature and causes. Pleural effusion involves the accumulation of excess fluid in the pleural cavity, the space between the lungs and chest wall. This fluid buildup can result from various conditions like infections, heart failure, or cancer. On the other hand, empyema specifically refers to a pleural effusion caused by a bacterial infection, usually stemming from pneumonia. Empyema is characterized by the presence of pus in the pleural space, indicating a more severe and infectious component compared to a standard pleural effusion.
