Case Discussion

Pleural effusion represents the abnormal accumulation of fluid in the pleural cavity. The characteristics of the fluid usually cannot be determined by a simple radiograph and further clinical correlation is necessary to properly identify it.

As pleural effusion is a generic term to denote the abnormal presence of fluid in the pleural cavity, it can be caused by many different conditions.
