Overview
Diagnosis of lung abscess is often based on radiologic results showing a cavitary lesion with air fluid level, though blood cultures are normally required to identify the specific pathogen.
Chest X Ray
- An irregularly shaped thick walled cavity with an air-fluid level is typically seen in lung abscess on chest x ray. [1]
- Abscess is often unilateral and single involving posterior segments of the upper lobes and the apical segments of the lower lobes as these areas are gravity dependent when lying down. [2]
- The presence of air-fluid levels implies rupture into the bronchial tree or rarely growth of gas forming organism.The extent of the air-fluid level within a lung abscess is often the same in posteroanterior or lateral views.
- Anaerobic infection may be suggested by cavitation within a dense segmental consolidation in the dependent lung zones.
- Lung infection with a virulent organism results in more widespread tissue necrosis.
- Up to one-third of lung abscesses may be accompanied by an empyema.[3]
- Repeat chest radiographs must be obtained to determine the response of antimicrobial therapy.
