[Tracheobronchopathia chondro-osteoplastica (author's transl)].

Tracheobronchopathia chondro-osteoplastica is a relatively rare abnormality, which has hardly been illustrated in the radiological literature. It has, however, been accurately defined pathologically and is of clinical significance by causing obstruction of the airways. The disease must be distinguished from changes in the trachea and bronchi due to ageing, which may be associated with calcification of the tracheal cartilage, but in which there is no thickening of the wall of the trachea.
