- Miliary tuberculosis
- Bronchiectasis
- COPD
- Lung cancer
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Read the picture as countless tiny uniform nodules spread evenly across both lungs. Step 2: Such a fine micronodular pattern arises when $Mycobacterium\ tuberculosis$ disseminates through the bloodstream, seeding the whole lung. Step 3: Each focus measures only 1 to 5 mm and the appearance is likened to scattered millet seeds, the origin of the term miliary; spleen and liver may be seeded too. Step 4: This is unlike bronchiectasis (dilated bronchi), COPD (air trapping) or lung cancer (a focal mass), so the diagnosis is miliary tuberculosis.\[\boxed{\text{Miliary tuberculosis}}\]
