CTICasesAspiration Lung Abscess
Imaging findings
Chest radiograph and CT show a very large, cavitating mass in the left upper lobe with multiple air-fluid levels and surrounding reactive pleuritis. High-attenuation branching material representing barium is present in the dependent lower lobes.
Key takeaways
Barium aspiration during a swallow study is a clear indicator of severe dysphagia and chronic micro-aspiration. Large lung abscesses can develop from aspirated oral secretions, presenting as large cavitating consolidations that must be managed carefully to avoid endobronchial spillage.
