COVID-19 = coronavirus disease 2019, ICU = intensive care unit, OP = organizing pneumonia.
Table 1.
Demographics, laboratory test and clinical outcome in COVID-19 patients with organizing pneumonia pattern.
Fig 2.
The evolution of CT findings across the three time groups (day 0–7, day 8–14, day >14) in COVID-19 patients with organizing pneumonia pattern.
GGO = ground glass opacity; with three signs = GGO, consolidation and linear opacity.
Table 2.
Comparisons of clinical characteristics and CT findings between non-severe and severe groups in COVID-19 patients with organizing pneumonia.
Fig 3.
Comparisons of CT findings between patients with complete absorption and residuals after discharge.
GGO = ground glass opacity; with three signs = GGO, consolidation and linear opacity. *, P< 0.05 indicated significant differences.
Fig 4.
A 66-year-old man who had been to Wuhan had fever for 4 days and discharged at day 28 after symptom onset.
(A) CT obtained on admission at day 4 after symptom onset shows multiple subpleural consolidation. (B) CT on day 11 shows progression with increased number and size of lung lesions. (C, E) CT on day 27 shows absorption with decreased density of the lesions. (D) CT on day 41 shows almost complete absorption of pulmonary lesions.
Fig 5.
A 55-year-old man who had fever for 6 days and discharged at day 31 after symptom onset.
(A) CT obtained on admission at day 6 after symptom onset shows focal GGO in bilateral lower lobe. (B) CT on day 10 shows progression with increased size and density of lung lesions. (C) CT on day 18 shows progression with increased density of the lesions. (D) CT on day 30 shows patchy consolidation and linear opacities of pulmonary lesions.
