CTICasesTransient Traction Bronchiectasis in COVID-19 Organizing Pneumonia
Imaging findings
CT chest in a patient post-COVID-19 infection shows bilateral, peripheral ground-glass opacities, reticulation, and bronchial dilation in an organizing pneumonia pattern. Follow-up CT 3 months later shows complete clearing of the parenchymal opacities and a return of the bronchial caliber to normal.
Key takeaways
During acute lung injury or organizing pneumonia (such as from COVID-19), temporary bronchial dilation can occur due to increased mechanical pulling of surrounding inflamed tissue, mimicking irreversible traction bronchiectasis. Recognizing that this bronchial dilation can be completely reversible is important to avoid over-calling lung fibrosis.
