Pulmonary abscess is a collection of pus (dead leukocytes and cellular debris) in the lung caused by bacterial infection. The germs that produce abscess can reach the lungs through two ways: 1) bronqui, through which infection-causing bacterial, such as pneumococci and streptococci, get into the lung lobules, causing pneumonia that result in abscess; 2) circulating blood, which carries germs or contaminated clots that block the capillaries in the alveoli. Thus, pulmonary or lung abscess is the result of an infectious disease. Although any person can develop a lung abscess, older people or weakened pecients suffering from HIV or anemia are more likely to get it.
Treatment: antibiotic, oxygen, aspiration and surgery.
