Tracheobronchomegaly associated with tracheobronchopathia osteochondroplastica: a case report

Area of Science:

• Pulmonology
• Rare Diseases
• Airway Pathology

Background:

• Tracheobronchomegaly (TBM) involves tracheal and bronchial dilatation due to elastic fiber atrophy.
• Tracheobronchopathia Osteochondroplastica (TO) is an uncommon airway disease characterized by cartilage and bone formation.
• The etiology of both TBM and TO is largely unknown, and their co-occurrence has not been previously documented.

Observation:

• This study presents a unique case of an elderly male patient.
• The patient exhibited a history of recurrent pneumonia over a six-year period.
• The diagnosis revealed the co-existence of Tracheobronchomegaly and Tracheobronchopathia Osteochondroplastica.

Findings:

• The case highlights the simultaneous presence of TBM and TO in a single patient.
• This finding expands the known clinical spectrum of these rare airway conditions.
• The patient's recurrent pneumonia is discussed in the context of these combined pathologies.

Implications:

• This report suggests that TBM and TO may co-occur more frequently than previously thought.
• Understanding this association could lead to improved diagnostic approaches for patients with complex airway issues.
• Further research is warranted to elucidate the potential pathogenetic links between TBM and TO.
