title: [Radiological methods in the diagnostics of extrinsic allergic alveolitis].
abstract: There were 77 patients with EAA under our observation with the following X-ray symptom groups: emphysematous-interstitial; parenchymatous-interstitial; pneumonic. The emphysematous-interstitial X-ray symptom group is the most non-specific for the X-ray diagnostics. The changes indicate to symptoms of impaired bronchial conductance of different expression and are relevant to clinical EAA options characteristic for the obstructive syndrome. The parenchymatous-interstitial X-ray symptom group is more characteristic for occupational EAA. In such cases the most important are changes in the lung parenchyma that have a diffusive character and are accompanied by general symptoms indicating to bronchial impairments of different severity. In pneumatic X-ray symptom group, the major X-ray symptom is presence of local sites of lung tissue consolidation of hypoventilation-infiltrative character that can be bilateral, multiple with a trend to migration.
