The CXR shows narrowing of the tracheal air column (Fig. 61.2) with calcification of the wall. Tracheal narrowing can be due to malignant causes (lung cancer, lymphoma, metastases) or benign causes (post tuberculosis, posttraumatic, amyloidosis, sarcoidosis, Wegener's, Tracheopathia Osteochondroplastica). Tracheopathia Osteochondroplastica (TO) is an extremely rare condition, characterized by the presence of multiple osseous and/or cartilaginous submucosal nodules (Fig. 61.3) protruding into the lumen of the airway. Bronchoscopy is diagnostic but treatment is nonspecific and supportive.
