The aim of this pictorial essay was to present the main computed tomography findings seen in diffuse diseases of the trachea. The
diseases studied included amyloidosis, tracheobronchopathia osteochondroplastica, tracheobronchomegaly, laryngotracheobronchial
papillomatosis, lymphoma, neurofibromatosis, relapsing polychondritis, Wegener's granulomatosis, tuberculosis, paracoccidioidomycosis,
and tracheobronchomalacia. The most common computed tomography finding was thickening of the walls of the trachea, with or
without nodules, parietal calcifications, or involvement of the posterior wall. Although computed tomography allows the detection and
characterization of diseases of the central airways, and the correlation with clinical data reduces the diagnostic possibilities, bronchoscopy
with biopsy remains the most useful procedure for the diagnosis of diffuse lesions of the trachea.
