Diagnosis With Brief Discussion

Diagnosis
tracheobronchopathia osteochondroplastica
Radiologic Findings
Fig 1. Chest PA shows irregular narrowing of trachea with consolidation in right lower lung zone with right pleural effusion.
Fig 2-4. CT scans reveals nodular calcification of tracheal wall and vocal cord calcification. And posterior membranous wall is spared.
Brief Review
Tracheobronchopathia osteochondroplastica (TPO) is an idiopathic benign disease characterized by the presence of diffuse cartilaginous or bony submucosal nodules protruding into the tracheobronchial lumen. The posterior membranous wall is distinctively spared because the nodules mainly originate in airway cartilages (1). TPO is rarely identified by bronchoscopy or chest computed tomography(CT) with a reported incidence of approximately 0.3%(3/1,000 autopsies) (2,3)
In TPO patients, chest X-ray data showed irregularity, scalloping, narrowing or calcification of the trachea and main bronchi. trachea and both main bronchi. The characteristics of chest CT scans showed tracheal narrowing and multiple 1–3 mm diameter submucosal nodules with or without calcification in the trachea and main bronchi (3).
