Having almost one year elapsed since the COVID-19 pandemic onset, the long-term radiologic consequences of COVID-19 can be evaluated. Although about 30% to 40% residual disease has been reported in mid-term follow-up, no survey on long-term radiologic changes has been conducted. To our knowledge through literature and our experience in follow-up of COVID-19 patients in the frontline, we classified the long-term radiological sequels into the following three groups: complete resolution, fibrotic-parenchymal sequels (mild, moderate, or extensive), and ischemic-parenchymal sequels(cavitation). For each group, some cases with interesting serial imaging were discussed in detail.
