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.
