Table 2. Computed tomography (CT) radiology patterns in chronic fibrosing interstitial pneumonia and the other interstitial lung diseases (ILDs).
| Patterns | Chronic fibrosing (n=107, %) | Other ILD (n=77, %) | Overall (n=184, %) |
|---|---|---|---|
| Normal | 13 (12.1) | 5 (6.5) | 18 (9.8) |
| Inflammatory | 66 (61.7) | 69 (89.6) | 135 (73.4)* |
| Ground-glass opacification | 61 (57.0) | 32 (41.6) | 93 (50.5)† |
| Nodular | 1 (0.9) | 35 (45.5) | 36 (19.6)* |
| Consolidation | 3 (2.8) | 13 (16.9) | 16 (8.7)* |
| Bronchial wall thickening | 6 (5.6) | 9 (11.7) | 15 (8.2) |
| Fibrotic | 76 (71.0) | 22 (28.6) | 98 (53.3)† |
| Reticular | 69 (64.5) | 16 (20.8) | 85 (46.2)† |
| Traction bronchiectasis | 31 (29.0) | 7 (9.1) | 38 (20.7)† |
| Volume loss | 17 (15.9) | 4 (5.2) | 21 (11.4)† |
| Honey combing | 11 (10.3) | 0 (0) | 11 (6.0)† |
| Bronchiolitis | 1 (0.9) | 11 (14.3) | 12 (6.5)* |
Binominal proportion test was used with normal approximation to calculate P value. *, P<0.05, radiology patterns are more common in the other ILD group; †, P<0.05, radiology patterns are more common in the chronic fibrosing interstitial pneumonia group.
