The lungs are often affected in multisystemic processes or in disorders that have their predominant manifestations in other organ systems. When this involvement is of a noninfectious nature, the radiographic patterns that result are dependent on whether the predominant involvement is in the end air space or the interstitium. Assessment of the type and distribution of the pattern is helpful in developing an appropriate differential diagnosis for these predominantly extrapulmonary diseases. In other patients, recurrent pulmonary infections occur because of disordered host defense. The resultant radiographic patterns then include diffuse end air space consolidation during episodes of acute pneumonia, lung abscesses, and, with healing, parenchymal scarring and possibly bronchiectasis. Specific radiographic findings may allow precise diagnosis in certain disorders.
