Etymology: L, effundere, to pour out
1 the escape of fluid, for example, from blood vessels as a result of rupture or seepage, usually into a body cavity. The condition is usually associated with a circulatory or renal disorder and is often an early sign of congestive heart disease. The term may be associated with an affected body area, as pleural or pericardial effusion. See also edema, transudate.
2 the outward spread of a bacterial growth.

effusion

Accumulation of fluid in various spaces of the body, or the knee itself, which is a frequent byproduct of injury. See Ascites, Peritoneal effusion, Pleural effusion, Pseudochylous effusion, Subdural effusion.

(e-fyu'zhŭn)
1. The escape of fluid from the blood vessels or lymphatics into the tissues or a cavity.
2. A collection of the fluid effused.

2. The collection of fluid in an abnormal site, as in a pleural effusion, a pericardial effusion or a joint effusion.

Effusion

The escape of fluid from blood vessels or the lymphatic system and its collection in a cavity, in this case, the middle ear.

effusion

extravasation of fluid into body tissues or cavities, such as a pleural effusion, or into joints where it causes swelling. In sport a joint effusion is a sign of significant damage to the joint. A knee filled with blood, rather than with joint (synovial) fluid, is called a haemarthrosis, an injury requiring immediate care (e.g. cruciate ligament damage in the knee).

effusion

escape of fluid or plasma from blood or lymphatic vessels into tissues, e.g. acute inflammatory response

effusion,

n flow of fluid (i.e., blood) into a body cavity; can be an indication of congestive heart disease.
