Reversible cystic dilatation of distal airways due to foreign body

South Med J. 1994 Mar;87(3):404-6. doi: 10.1097/00007611-199403000-00022.


We describe a child with foreign body aspiration whose chest radiograph showed an unusual appearance of multiple round lucencies simulating bronchiectasis. This appearance is contrary to the usual appearance of emphysema due to the check-valve type of obstruction. This report is particularly useful for pediatricians and family physicians, who should be aware of the variable appearances of foreign body aspiration. Our case emphasizes the necessity of early bronchoscopy in pediatric patients with unresolving pneumonia.
