3. HRCT-1

4. HRCT-1
• What is the major abnormality in this case?
• a) Linear opacities
• b) Nodules
• c) Consolidation
• d) Ground-glass opacity

5. HRCT-1
• 2. What is the distribution of the
abnormalities?
• a) Bronchial/bronchiolar
• b) Interlobular septal
• c) Centrilobular
• d) Pleural

6. HRCT-1
• Find a row of centrilobular nodules within 5
mm of the pleura in the right lung.
• Find 2 rosettes in the right lung.
• Find a tree-in-bud pattern in the right lung.
• Find bronchial wall thickening in longitudinal
or cross-section in the right lung (one of each
is marked).

7. HRCT-1

9. • This slice of lung with bronchopneumonia
shows a pattern similar to that shown in the
HRCT image above.
• Find a row of subpleural centrilobular
nodules.
• Find rosettes (2 are marked).

11. After treatment.

12. Q
• What changes have occurred after therapy?

13. Answer
Marked resolution of
diffuse centrilobular nodules
tree-in-bud changes
bronchial/bronchiolar wall thickening

14. HISTOLOGY

15. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole

16. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks
cartilage.

17. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks cartilage.
• 2. What are the collections of cells in the thickened
airway interstitium?
• a) Lymphoid infiltrates
• b) Lymphoid follicles
• c) Infiltrates of PMNs
• What is the histologic diagnosis?

18. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks cartilage.
• 2. What are the collections of cells in the thickened
airway interstitium?
• a) Lymphoid infiltrates
• b) Lymphoid follicles
• c) Infiltrates of PMNs
• What is the histologic diagnosis?
• Chronic follicular bronchiolitis

19. DIAGNOSIS?
Diffuse bronchitis and bronchiolitis

20. Summary
diagnostic features of diffuse
bronchitis/bronchiolitis on HRCT
• Diffuse well- and poorly-defined centrilobular
nodules
• Tree-in-bud pattern
• Thickening of bronchial walls
• ± Patchy pneumonic consolidation
