Laryngotracheobronchial papillomatosis: findings on computed tomography scans of the chest.
OBJECTIVE
To present the findings of computed tomography (CT) scans of the chest in patients with laryngotracheobronchial papillomatosis.


METHODS
We retrospectively analyzed CT scans of eight patients, five males and three females, ranging from 5 to 18 years of age with a mean age of 10.5 years. Images were independently reviewed by two radiologists. In discrepant cases, a consensus was reached.


RESULTS
The most common CT findings were intratracheal polypoid lesions and pulmonary nodules, many of which were cavitated.


CONCLUSIONS
In patients with laryngotracheobronchial papillomatosis, the most common tomographic finding was the combination of intratracheal polypoid lesions and multiple pulmonary nodules, many of which were cavitated.
