CTICasesPost-COVID-19 Fibrosis
Imaging findings
A middle-aged to elderly patient who had COVID-19 months earlier and was intubated presents with persistent dyspnea. CT shows residual fibrosis in a pattern consistent with organizing residua of diffuse alveolar damage, with the inflammatory component not fully resolved.
Key takeaways
Severe COVID-19, particularly in patients who required intubation, can leave residual fibrosis reflecting organized diffuse alveolar damage, a classic post-injury pattern. As management has improved and severe cases survive, residual organizing pneumonia and fibrosis are increasingly seen weeks to months out, with some clearing slowly and some persisting.
