Adult-onset disseminated tracheobronchial papillomatosis: Ct features

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 air-ways. Some of the nodules showed central cavitation. In a patient with cen-trilobular opacities, some of which cavitate, on HRCT and concomitant en-dobronchial or endotracheal abnormality, disseminated papillomatosis should be considered in the differential diagnosis, particularly if there is a history of hoarseness or laryngeal disease.
