This 57-years old man was tested positive in mid-May. He had a scan in June and now in September. While there is resorption of some of the ground glass and reticular opacities between Jun and Sept, some of the “normal” lung now shows ground glass. The patient however is stable and has not worsened.

Is this just a normal evolution given that this is an angiopathy / vasculopathy, we have no experience of? What will happen another 3 months further down the line? Can doctors/radiologists from China, Italy and Iran who would likely have longer term follow-up shed some light on this phenomenon, which seems to look like the “creeping substitution” of avascular necrosis in the femoral neck.

Maybe we should call this “creeping ground glass” ?
