title: Parapneumonic empyema diagnosed by chest radiograph and computed tomography.
abstract: Pleural effusion is commonly seen associated with pneumonia. When this progresses to empyema, directed therapy is frequently required. Chest radiographic and computed tomography findings can help distinguish empyema from a transudative pleural effusion.
