Covid-19 is a viral infectious disease in which most patients present with respiratory symptoms ^1-6. Radiologists should become familiar with the tomographic temporal stages of this disease ^1-6. The most prominent feature of the progressive stage (stage 2, day 5-8 from symptoms onset) are ground-glass opacities (GGOs) with the crazy-paving pattern; In the peak stage (stage 3, day 9-13), consolidation becomes prevalent; After 14 days, (stage 4), in the late or absorption stage the lesions undergo a gradual absorption, leaving tenuous residual GGOs and subpleural parenchymal bands ^1-6.

This case illustrates the temporal CT changes of progressive / peak stages (stages 2/3) with gradual improvement to the beginning of the absorption stage (stage 4) of COVID-19 pneumonia.
