    Tracheal bronchus is a rare congenital anomaly where an extra airway branches from the trachea. It can cause recurrent lung infections, especially in the right upper lobe, sometimes requiring surgical removal.

    Area of Science:

    • Medical Science
    • Pulmonology
    • Embryology

    Background:

    • Tracheal bronchus is a congenital anomaly originating from the trachea.
    • It occurs in 0.1-5% of the population due to aberrant tracheal outgrowth.
    • Often diagnosed incidentally during respiratory investigations.

    Purpose of the Study:

    • To describe the characteristics of tracheal bronchus.
    • To highlight its association with chronic pulmonary diseases.
    • To outline diagnostic and therapeutic approaches.

    Main Methods:

    • Literature review of tracheal bronchus cases.
    • Analysis of diagnostic methods like bronchoscopy and bronchography.
    • Review of clinical presentations and treatment outcomes.

    Main Results:

    • Tracheal bronchus can lead to conditions like emphysema, atelectasis, and recurrent pneumonia.
    • Association with other anomalies such as tracheal stenosis and Down's syndrome is noted.
    • Asymptomatic cases require no treatment.

    Conclusions:

    • Tracheal bronchus is an uncommon anomaly with varied clinical implications.
    • Symptomatic cases, particularly recurrent right upper lobe disease, may necessitate surgical resection.
    • Early diagnosis and appropriate management are crucial for patient outcomes.
