Chest X-rays reveal distinct pulmonary tuberculosis (TB) patterns in Human Immunodeficiency Virus (HIV)-positive individuals. HIV-positive patients show increased lymphadenopathy, pleural effusion, and miliary patterns, with less cavitation and upper zone involvement compared to HIV-negative patients.
Area of Science:
- Radiology
- Infectious Diseases
- Pulmonology
Background:
- Pulmonary tuberculosis (TB) presents varied radiographic findings.
- Human Immunodeficiency Virus (HIV) infection can alter TB's typical presentation.
- Understanding these differences is crucial for accurate diagnosis and management.
Purpose of the Study:
- To compare chest radiographic findings of pulmonary TB in HIV-positive versus HIV-negative individuals.
- To identify specific radiological markers associated with TB in the context of HIV co-infection.
- To elucidate how HIV status influences the pattern of pulmonary TB on chest X-ray.
Main Methods:
- Retrospective analysis of chest radiographs from 50 HIV-positive TB patients and 100 HIV-negative TB patients.
- Systematic review of radiographic features including lymphadenopathy, pleural effusion, miliary pattern, cavitation, and zone of involvement.
- Statistical comparison of the incidence of these features between the two groups.
Main Results:
- HIV-positive patients had significantly higher rates of thoracic lymphadenopathy (36% vs 8%), pleural effusion (28% vs 10%), and miliary pattern (12% vs 2%).
- Cavitation was less frequent in HIV-positive individuals (8% vs 35%).
- Upper zone involvement was significantly less common in HIV-positive patients (38% vs 77%).
Conclusions:
- HIV co-infection significantly alters the chest radiographic appearance of pulmonary TB.
- Radiographic findings like lymphadenopathy, pleural effusion, and miliary patterns are more prevalent in HIV-positive TB patients.
- The reduced incidence of cavitation and upper zone involvement in HIV-positive patients highlights unique disease manifestations requiring tailored diagnostic approaches.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
