Thoracic empyema usually results from pulmonary infection or thoracic surgery. Antibiotic therapy is an essential part of the treatment, but surgical techniques to drain the pleural fluid and obliterate the empyema space often are required. ⋯ Emphasis is placed on a thorough understanding of the pathophysiology and natural history of empyema for selection and timing of appropriate treatment. Thoracic imaging techniques play a substantial role in the evaluation and treatment of empyema and in assessing the outcome of surgical therapy.
