5. Thoracic CT shows the right upper lobe opacity appears relatively stable or perhaps minimally improved compared to the thoracic CT 2 months earlier (Figure 11)
Repeat thoracic CT (Figure 13) shows that the right upper lobe opacity is relatively stable, perhaps minimally improved, but is neither clearly progressed nor clearly regressed. No new small nodular opacities, pleural disease, or evidence of lymph node enlargement is present.
The patient remained stable over the next two months, after which unenhanced thoracic CT was performed (Figure 14), which was interpreted as worsening of the right upper lobe process.
