[Tracheo-bronchopathia chondro-osteoplastica. X-ray computed tomographic signs]

Area of Science:

• Pulmonology
• Radiology
• Pathology

Background:

• Tracheobronchopathia chondro-osteoplastica (TCO) is an exceptionally rare condition.
• Characterized by progressive, benign, cartilaginous and osseousnewNode formations within the trachea and bronchi.

Observation:

• This case report details a patient diagnosed with TCO.
• High-resolution computed tomography (HRCT) revealed characteristic radiological patterns.
• Key findings included tracheal stenosis and calcified intraluminal projecting formations originating from the tracheal wall.

Findings:

• HRCT is a valuable tool for diagnosing TCO, demonstrating specific radiological features.
• Endoscopy and histological examination are definitive for diagnosis.
• The etiology, long-term prognosis, and specific treatments for TCO are currently unknown.

Implications:

• Highlights the importance of HRCT in identifying rare airway diseases like TCO.
• Underscores the need for further research into the causes and management of TCO.
• Emphasizes the diagnostic challenges posed by the disease's rarity and long latency period.
