Discussion of Tracheobronchopathia osteochondroplastica
- Tracheobronchopathia osteochondroplastica is characterized by development of osseous or cartilaginous nodules or both in the submucosa of the trachea and bronchial walls
- Very rare condition.
- Nodules are associated with tracheal cartilage, sparing the posterior membrane.
 Imaging Findings for Tracheobronchopathia osteochondroplastica
- CT findings include thickened tracheal cartilage with small 3- to 8-mm calcific nodules along its inner aspect, protruding into the tracheal lumen.
- The appearance is much more irregular than that seen with normal cartilage calcification.
- Malacia is not present.
