CTICasesAirway obstruction from aspirated tooth
Imaging findings
CT scan shows an extensive necrotizing process with consolidation, cavitation, and fluid levels in the superior segment of the right lower lobe. A dense calcified structure matching a canine tooth is visible obstructing the corresponding segmental bronchus.
Key takeaways
Foreign body aspiration (such as a tooth) can cause chronic or acute bronchial obstruction, leading to post-obstructive necrotizing pneumonia. A history of trauma or dental work is a key clinical clue.
