Identify the infection from the chest X-ray of a patient with low-grade fever?
Ans-C. Miliary TB
- Miliary tuberculosis is due to hematogenous dissemination of tubercle bacilli.
- This is due to the hematogenous spread of infection and may be seen in both primary and post-primary disease.
- At first, the chest radiograph may be normal but then small, discrete nodules, 1-2 mm in diameter, become apparent, evenly distributed throughout both lungs. These may enlarge and coalesce but with adequate treatment, they slowly resolve.
- Dense opacities occur with calcification and metallic dust disease.
