2. Frontal and lateral chest radiography shows a focal, poorly defined right base opacity
Frontal and lateral chest radiograph shows a focal, somewhat oblong and poorly defined right base opacity, seen on the frontal projection, but not well visualized on the lateral projection (Figure 2).
Figure 2. Frontal (A) and lateral (B) chest radiography shows a poorly defined, faintly nodular opacity at the right base (arrow), primarily seen on the frontal projection.
No evidence of peribronchial or mediastinal lymph node enlargement is seen, no are linear or reticular abnormalities. The heart size appears normal.
