This trauma patient had significant craniofacial injuries and aspirated a tooth. It lodged in the right lower lobe bronchus, causing post-obstructive consolidation. Inhaled foreign bodies may be complicated by haemoptysis, air trapping, post-obstructive collapse, pneumonia or bronchiectasis. Removal of the foreign body is usually performed via bronchoscopy.
