    Area of Science:

    • Pulmonology
    • Infectious Diseases
    • Radiology

    Background:

    • Tuberculosis (TB) predominantly affects the upper lung fields.
    • Lower lung field TB is less common but presents unique challenges.

    Purpose of the Study:

    • To characterize the clinical, radiological, and bronchoscopic features of lower lung field tuberculosis.
    • To evaluate the role of bronchoscopy in diagnosing and managing this condition.

    Main Methods:

    • Retrospective analysis of 65 patients with lower lung field TB over five years.
    • Review of clinical data, chest X-rays, sputum smears for acid-fast bacilli (AFB), and bronchoscopy findings.
    • Correlation of bronchoscopic findings with treatment outcomes.

    Main Results:

    Related Experiment Videos

    • Lower lung field TB occurred in 5.1% of pulmonary TB admissions, predominantly in elderly females.
    • Common symptoms included cough, chills, fever, and hemoptysis; basal segments and middle lobe were most affected.
    • Bronchoscopy confirmed endobronchial involvement in 32/42 patients, revealing ulcerative granuloma, fibrostenosis, and submucosal infiltration.

    Conclusions:

    • Lower lung field TB exhibits distinct demographic and clinical patterns.
    • Bronchoscopy is crucial for diagnosing endobronchial lesions and guiding surgical intervention in severe cases.
