Changing patterns in pulmonary tuberculosis.

T L Tytle, T H Johnson

    Southern Medical Journal
    |October 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    Initial chest X-rays for active tuberculosis (TB) often missed diagnoses, with less than half suspected initially. Pulmonary TB findings poorly correlated with extrapulmonary TB, and uncommon lung locations were frequent.

    Area of Science:

    • Radiology
    • Infectious Diseases
    • Pulmonology

    Background:

    • Active tuberculosis diagnosis can be challenging.
    • Initial presentation often lacks clear suspicion for tuberculosis.

    Purpose of the Study:

    • To evaluate the diagnostic utility of initial chest roentgenograms in active tuberculosis.
    • To assess the correlation between pulmonary and extrapulmonary tuberculosis.
    • To identify common pulmonary patterns in active tuberculosis.

    Main Methods:

    • Retrospective review of initial chest roentgenograms.
    • Analysis of 182 consecutive adult patients with confirmed active tuberculosis.

    Main Results:

    • Less than 50% of active tuberculosis cases were known or suspected at initial presentation.

    Related Experiment Videos

  • Low correlation observed between radiologically evident pulmonary tuberculosis and extrapulmonary tuberculosis.
  • A significant proportion of cases presented with uncommon pulmonary locations.

    • Conclusions:

    • Initial chest roentgenograms have limitations in diagnosing active tuberculosis.
    • Radiographic findings of pulmonary tuberculosis do not reliably indicate extrapulmonary involvement.
    • Awareness of uncommon presentations and patterns is crucial for tuberculosis diagnosis.
