Investigation on the radiological findings of COVID‐19‐associated pneumonia have yielded little, if any, information that are mostly unspecific. Progressive lung lesions are usually detected in patients with COVID‐19, about 1 week after the onset of signs and symptoms (Ooi et al., 2004). The lesions then become aggravated during the 2nd week, and lead to formation of irregular reticular opacities mixed with ground glass opacities (GGOs), which can be detected by CT at the fourth week. In a recent cohort study, 85.7% (54/63) of subjects with COVID‐19‐associated pneumonia showed disease progression, defined by an increased extent of GGO, on early follow‐up CT (Pan et al., 2020). Pulmonary fibrous cords was reported in one particular patient that displayed signs of improvement, as the inflammatory secretions had been absorbed (Pan & Guan, 2020). Long‐term complications of COVID‐19 in patients with severe pneumonia might include an array of fibrotic changes often observed in the late stages of lung injury, for example, reticulation, interlobular septal thickening, and traction bronchiectasis (Kim, 2020).
