Pulmonary abscess in children

Abscess of lung refers to inflammatory lesions of the lung parenchyma caused by various bacterial infections. Necrosis liquefies and forms a cavity containing pus. Mainly secondary to pneumonia, followed by sepsis. Occasionally purulent lesions from adjacent tissues, such as liver abscesses, subcondylar abscesses, or empyema spread to the lungs. In addition, tumor or foreign body compression can cause bronchial obstruction and secondary purulent infections, pulmonary flukes, roundworms, and amoeba can also cause lung abscesses. Primary or secondary immune dysfunction and the use of immunosuppressive drugs can promote it.
