Abstract
This chapter describes the two major categories and appearances of lung disease (air space, interstitial), as well as other classic patterns and signs (ground-glass opacity, tree-in-bud pattern, mosaic attenuation, and the silhouette and spine signs).

Air-space disease (aspiration). (b) In another patient, there are ill-defined areas of opacification in the left lung (arrow) [4] (TIF 559 kb)
Fig. e3.7
Interstitial pulmonary edema. Loss of the normal sharp definition of pulmonary vascular markings. Horizontal lines of increased opacity (Kerley B lines) represent fluid in the interlobular septa [1] (TIF 664 kb)
