Lobules at the pleural surface may have a variety of appearances, but they are often longer than they are wide, resembling a cone or truncated cone. Within the central lung, thickened septa usually outline lobules that are 1 to 2.5 cm in diameter and appear polygonal, or sometimes hexagonal, in shape (Fig. 3-2).
Lobules delineated by thickened septa commonly contain a visible dotlike or branching centrilobular pulmonary artery. The characteristic relationship of the interlobular septa and centrilobular artery is often of value in identifying each of these structures.
FIGURE 3-2 Smooth interlobular septal thickening in patient with pulmonary edema.
A lobule in the anterior lung outlined by interlobular septa (yellow arrows) shows dotlike pulmonary artery branches in its center (red arrows). Small nodular opacities (blue arrows) seen in relation to some septa represent pulmonary vein branches seen in cross section.
