Lung abscess is a type of liquefactive necrosis of the lung tissue and formation
of cavities (more than 2 cm) containing necrotic debris or fluid caused by
microbial infection. It can be caused by aspiration, which may occur during
altered consciousness and it usually causes a pus-filled cavity. Moreover,
alcoholism is the most common condition predisposing to lung abscesses. Lung
abscess is considered primary (60%) when it results from existing lung
parenchymal process and is termed secondary when it complicates another process,
e.g., vascular emboli or follows rupture of extrapulmonary abscess into lung.
There are several imaging techniques which can identify the material inside the
thorax such as computerized tomography (CT) scan of the thorax and ultrasound of
the thorax. Broad spectrum antibiotic to cover mixed flora is the mainstay of
treatment. Pulmonary physiotherapy and postural drainage are also important.
Surgical procedures are required in selective patients for drainage or pulmonary
resection. In the current review we will present all current information from
diagnosis to treatment.
