Conclusion

In general, lesions on chest CT show progression in the first days after the onset of symptoms, showing improvement a few weeks after the start of treatment, depending on each case. Patients with few lesions may not progress, progressing directly to radiological resolution. Some patients, may progress with fibrosis and remain with CT changes for the long term.
Some patients, especially the elderly and those who had multiple lesions and extensive involvement of the parenchyma, may progress with fibrosis and remain with CT changes for the long term.
The development of cystic lung lesions in patients with COVID-19 has already been described recently, but it should be the reason for further studies in order to better understand the pathophysiology of the occurrence of these lesions.
