[Chronic fibrosing alveolitis and lung fibrosis--frequency and distribution of radiographic symptoms].

In 95 patients with histologically or immunologically diagnosed interstitial lung diseases (44 pts. with chronic fibrosing alveolitis, 6 with allergic alveolitis, 11 with chronic diffuse fibrosis, 34 pts. with localized fibrosis) the radiographic symptoms of interstitial and accompanying alveolar and pleural alterations are estimated by a semiquantitative score, with regard to location and intensity. No diagnosis-relevant differences are found. Nodular densities are seen on the radiographs of all patients. In most of the cases (82%) they are accompanied by reticular shadows. Irreversible "honeycomb"-cysts are found in 27% of patients, alveolar and pleural reactions in 22% and 28% respectively. An impressive shrinkage is found in 16%.
