Three-month follow-up CT scan of a patient after COVID-19 pneumonia presenting with exertional dyspnoea. Sharply demarcated areas of hypoattenuating lung parenchyma are depicted in both upper lobes (a). Reading the same acquisition on inspiration with narrow window settings on a series reconstructed in thin slices with soft kernel facilitates the detection of these abnormal areas and enforces a mosaic-like attenuation pattern (b). An additionally performed expiratory scan confirms the SAD owing to air trapping that matches with several hypoattenuating areas detected in (c). Note the predominant hypoattenuation pattern in this case

Three months after COVID-19 and ARDS, CT shows severe architectural distortion and traction bronchiectasis (arrowhead in c and d). These findings are frequent in patients that recovered from ARDS. However, multi-lobular hypoattenuation pattern is also present (arrows) on axial 1-mm-thick slices reconstructed with lung kernel (a) and 10-mm-thick minimum intensity projections (mIP) slices with soft kernel (b), and on coronal reformats 1-mm-thick reconstructed with lung kernel (c) and 10-mm-thick minimum intensity projections with soft kernel (d). The mIP post-processing (b, d) highlights a geographic, lobular hypoattenuation pattern that most likely represents multifocal small airways disease. Presumably hyperinflated lobules further exhibit convex perilobular septae towards normal lung parenchyma (small arrows) that should correspond to an air trapping on expiration. Note that the normal lung parenchyma (stars) is more easily assessed on mIP reformats with narrow window settings (b, d), than on classical lung analysis (a, c). Note pneumatoceles in subpleural location described in COVID-19 pneumonia
