Adult-Onset Disseminated Tracheobronchial Papillomatosis

Abstract
The high resolution CT (HRCT) findings in an adult with disseminated tracheobronchial papillomatosis are discussed. In addition to polypoid masses within the trachea and main bronchi, diffuse ill-defined parenchymal centrilobular opacities were present; these reflect lesions within the small airways. Some of the nodules showed central cavitation. In a patient with centrilobular opacities, some of which cavitate, on HRCT and concomitant endobronchial or endotracheal abnormality, disseminated papillomatosis should be considered in the differential diagnosis, particularly if there is a history of hoarseness or laryngeal disease.
