What Is Pleural Effusion?
3. Exudative Effusions
Pleural effusion can be broken down into two main categories, one of which is exudative effusions. This means the fluids involved are rich in proteins. It is the least common of the two varieties, and it is caused when the pleura somehow become damaged. This damage tends to occur by from diseases, or through physical injury.
Lung injuries are one potential cause of exudative effusions. Another potential cause is tumors that might cause physical damage to the membranes.
