Lung abscess can also be caused by the spread of other infections from the liver, abdominal cavity, or open chest wounds. Rarely, AIDS patients can develop lung abscess from Pneumocystis carinii and other organisms that take advantage of a weakened immune system. Lung abscess is usually slow to develop.
An abscess is a collection of pus that has accumulated within a tissue because of an inflammatory process in response to either an infectious process or other foreign materials. It is a defensive reaction of the tissue to prevent the spread of infectious materials to other parts of the body.
