This 52 years old man presented with mild disease that progressed in 3 days. He was Covid negative but breathless and a scan done 1 month later shows dense opacities with traction bronchiectasis.

Is this fibrosis? Or resolving organizing pneumonia? Many of these tend to regress further as we shall see in future cases and unless there is frank honeycombing or volume loss, it may be difficult to label this as fibrosis. We just read them and describe them and mention whether there is progression or regression, without using the label “fibrosis”, especially on the 1 month follow-up scans.
