Identify the infection from the chest X-ray of a patient with low-grade fever?
Show Hint
Uniform 1-2 mm millet-seed nodules across both lungs with low-grade fever.
Updated On: Jun 23, 2026
- ILD
- Bronchopneumonia
- Miliary TB
- Consolidation
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Focus on the radiographic texture - countless tiny, equal-sized nodules of roughly $1$ to $2\,\text{mm}$ scattered uniformly across both lungs in a febrile patient.
Step 2: This fine, symmetric miliary shower arises when tubercle bacilli spread through the bloodstream, seeding both lungs simultaneously, and can complicate either primary or post-primary tuberculosis.
Step 3: The film may look clear at first, then the discrete nodules emerge; appropriate anti-TB therapy leads to slow clearance.
Step 4: Ruling out alternatives: ILD shows reticulonodular or honeycomb fibrosis, bronchopneumonia shows patchy asymmetric infiltrates, and lobar consolidation shows a dense segmental opacity with air bronchograms - none match the uniform miliary pattern.
\[\boxed{\text{Miliary TB}}\]
