CTICasesLentil aspiration
Imaging findings
Chest CT shows mucus plugging and dilated bronchi radiating out into the left lower lobe, with a small fat-attenuation foreign body in the left lower lobe bronchus, in a patient with a history of prior consolidations in the right lower lobe and a large hiatal hernia. Bronchoscopy confirmed an obstructing bean/lentil.
Key takeaways
Food aspiration (such as of a lentil or bean) can present as chronic endobronchial obstruction, mimicking bronchogenic carcinoma on CT. Clues include fat-attenuation material within the bronchial lumen and prior aspiration events in dependent lung zones.
