A 75-year-old male patient with history of lung emphysema and had received “Phizer-Biontech” vaccine then got COVID-19 infection. A, B Axial chest CT cuts (lung window) showed bilateral centrilobular emphysema as well as peripheral located and to lesser extent bronchocentric ground-glass pneumonic patches with cystic changes. C CT-Volumetry of the pathological lung parts averages 634 cc. D CT-Volumetry of total lung volume averages 2591 cc. So, 25% of the lung parenchyma was diseased (Score 1)
