From: Predicting lung fibrosis in post-COVID-19 patients after discharge with follow-up chest CT findings
Fifty-nine-year-old male: he has DM; peak CT severity score 10; consolidation/crazy-paving score 8. No ICU admission; laboratory results show lymphopenia, high CRP, d-dimer, and serum ferritin. Steroid was given; length of stay during hospitalization is 10 days. Peak CT (a–d) shows bilateral peripheral consolidation patches mainly in the lower lobes (arrows). Follow-up CT 2 months after discharge (e–h) shows residual fibrosis with parenchymal bands, coarse reticular pattern (arrows), and atoll sign (black arrow in g).
