1. Thoracic CT shows continued interval improvement in the bibasilar opacities
Thoracic CT shows that the bibasilar opacities seen at CT abdomen at presentation (Figure 2) and on follow up CT (Figure 3) continue to improve, with no new or migratory pulmonary opacities and no evidence of new or increasing lymph node enlargement.
The patient underwent yet another thoracic CT, now about 5 months following initial presentation (Figure 5), which showed near-complete resolution of the bibasilar pneumonia.
Figure 5. Representative images from the axial unenhanced thoracic CT performed over 5 months following the initial presentation abdominal CT (Figure 2) and nearly 4 months following Figure 3 shows near complete resolution in the bilateral lower lobe nodular-appearing consolidation.
The patient clinically improved as well, and did well for the next 8 months, at which time he again presented with cough, shortness of breath, and some malaise, unimproved with another course of azithromycin, to which corticosteroids were added. During this time the patient presented to the Emergency Room with the same complaints, and his oxygen saturation was noted to be 93% on room air, decreasing to 88% with hallway exercise. Frontal and lateral chest radiography (Figure 6) was performed.
