    Tracheobronchopathia osteochondroplastica (TO) is a rare condition causing bone spurs in airways. This case highlights TO diagnosis in a patient with pneumonia, confirmed via biopsy and imaging.

    Area of Science:

    • Pulmonology
    • Pathology
    • Radiology

    Background:

    • Tracheobronchopathia osteochondroplastica (TO) is a rare disease characterized by ossified projections in the trachea and bronchi.
    • TO is often discovered incidentally during postmortem examinations.
    • This case presents a unique clinical scenario where TO was suspected in a patient with pneumonia.

    Observation:

    • The patient exhibited symptoms suggestive of a slowly resolving pneumonia.
    • Radiographic evaluation and bronchoscopic findings raised suspicion for TO.
    • Histopathologic analysis of a tracheal biopsy specimen confirmed the diagnosis.

    Findings:

    • Pulmonary function tests were largely normal.
    • Flow-volume loops were particularly informative for diagnosing TO and guiding follow-up.

  • The study details the diagnostic process for a rare case of TO.

    • Implications:

    • This case underscores the importance of considering TO in patients with persistent respiratory symptoms, even when pneumonia is suspected.
    • Diagnostic imaging and bronchoscopy play crucial roles in identifying TO.
    • Flow-volume loop analysis can be a valuable, non-invasive tool for TO diagnosis and monitoring.
