B Axial lung window CT showed sub-pleural small ground-glass nodular opacity in the posterior segment of the right upper lobe (orange arrow). C–D Axial 3D volumetry cuts highlighted the bilateral basal small sub-pleural ground-glass opacities. The pathological lung volume was around 1% of the total lung volumeBack to article page
