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.  \nKeywords: Thoracic diseases; Tracheal diseases; Tomography, X-ray computed; Trachea.  \n* Study carried out in the Departments of Radiology of the Universidade Federal Fluminense – UFF, Fluminense Federal University – and of the Universidade Federal do Rio de Janeiro – UFRJ, Federal University of Rio de Janeiro – Rio de Janeiro (RJ) Brazil.  \n1.

The main causes of focal involvement are primary tracheal neoplasms, lesions of traumatic origin, and some infectious diseases. Diffuse involvement, however, is caused by a wide array of conditions, including amyloidosis, tracheobronchopathiaosteochondroplastica, relapsing polychondritis, laryngotracheobronchial papillomatosis, tracheobronchomegaly, neurofibromatosis, tuberculosis and other granulomatous infections, such as Wegener’sgranulomatosis, as well as lymphomas.(1-3)  \nAbnormalities of the trachea are rare in daily clinical practice and, althou","cbCaiiN5xKtBzROw","https://ap.wps.com/l/cbCaiiN5xKtBzROw","pdf",1630437,"English","# Abstract\n# Tracheal disease background\n## Focal vs diffuse involvement\n## Clinical and imaging role of CT\n# CT technique and interpretation\n## Multiplane reconstructions and virtual bronchoscopy\n## Need for bronchoscopy with biopsy\n# Diffuse tracheal diseases covered\n## Amyloidosis and other listed disorders","[{\"question\":\"What diffuse tracheal diseases are discussed in the pictorial essay?\",\"answer\":\"The essay covers amyloidosis, tracheobronchopathia osteochondroplastica, tracheobronchomegaly, laryngotracheobronchial papillomatosis, lymphoma, neurofibromatosis, relapsing polychondritis, Wegener’s granulomatosis, tuberculosis, paracoccidioidomycosis, and tracheobronchomalacia.\"},{\"question\":\"What is the most common computed tomography finding in diffuse tracheal disease?\",\"answer\":\"The most common CT finding is thickening of the tracheal walls, which may occur with or without nodules, parietal calcifications, or posterior wall involvement.\"},{\"question\":\"Why is bronchoscopy with biopsy still considered the most useful procedure?\",\"answer\":\"Computed tomography helps detect and characterize central airway diseases and clinical correlation can narrow the differential, but bronchoscopy with histopathological study remains the definitive method for diagnosing diffuse tracheal abnormalities.\"}]","Pictorial Essay - Diffuse Tracheal Abnormalities: Computed Tomography Findings - read online free | PDF"]
