Severity scores for chest computed tomography findings
| Pattern | Presence on Any Scan (n = 18 patients) | Highest Severity Score (n = 18 patients) |
||||
|---|---|---|---|---|---|---|
| 0 | 1 | 2 | 3 | |||
| Bronchiectasis | 14 (77.8) | 4 (22.2) | 11 (61.1) | 3 (16.7) | 0 (0.0) | |
| Cavitation | 1 (5.6) | 17 (94.4) | 1 (5.6) | 0 (0.0) | 0 (0.0) | |
| Consolidation | 7 (38.9) | 11 (61.1) | 2 (11.1) | 4 (22.2) | 1 (5.6) | |
| Cyst | 4 (22.2) | 14 (77.8) | 3 (16.7) | 1 (5.6) | 0 (0.0) | |

| Larger nodules | 16 (88.9) | 2 (11.1) | 7 (38.9) | 4 (22.2) | 5 (27.8) | |
| Septal thickening | 13 (72.2) | 5 (27.8) | 9 (50.0) | 3 (16.7) | 1 (5.6) | |

Sixty scans were available for the 18 patients with lung lesions; each patient could have multiple scans. The first column shows how many patients manifested a particular pattern on any one of their computed tomographic scans. The severity score columns show the highest severity score for each pattern for each patient across all of their scans. Severity was rated on a scale of 0–3 for each pattern on each chest computed tomographic scan. If all scans for a patient had a severity of 0 for a particular pattern, that pattern was considered absent. If any scan had had a nonzero score for a pattern, that pattern was considered present.
