The lung window in axial and sagittal position of multi-detector spiral CT shows that the bilateral basal lung isthmus is connected, extending behind the pericardium and crossing the midline for fusion. The left lower lung basal segment has sparse lung markings, with increased transparency, and patchy shadows can be seen near the spine at the bottom of both lungs.

There was an obvious pleural interface between the isthmus and the left lung (arrow) (Figures 1 and 2).

The three-dimensional volume-rendered imaging of the bronchus shows that the bronchial branches of the lower lobe of the left lung are thinner than those of the right side. Cystic changes can be seen at the beginning of the lower lobe of the left lung. The outer and posterior basal segments of the lower lobe of the left lung fuse at the beginning, and the distal branches are sparse (arrows).

The three-dimensional volume-rendered imaging of the bronchus (Figure 4) showed that the bronchial branches of the lower lobe of the left lung were thinner than those of the right side.
Maximum intensity projection (MIP) can be seen in the basal segment of the lower lobe of both lungs, with the left lung as the focus, and multiple calcified nodules can be seen in it.

Thoracic CT angiography scanning (Figures 5 and 6): consolidation shadow could be seen in the basal segment of the lower lobe of both lungs, with the left lung as the focus, and multiple calcified nodules could be seen in it.
