Effusion - Definition

February 2017


Definition


Effusion is an accumulation of gas or liquid in an area of the organism that normally does not contain it. These affected regions are generally natural cavities such as a joint or "envelope" like the pleura, the peritoneum, or the pericardium. Pleurisy, for example, is an effusion of the pleura, pericarditis an effusion of the pericardium, etc. Effusion is generally preceded by inflammation, either due to a virus or a violent traumatism.
