[Inflammatory pulmonary lesions: resolutions and residuals (author's transl)]

There are different patterns of development and resolution of inflammatory alveolar and interstitial pulmonary lesions. Delayed resolution of peripheral pneumonia results in lung shrinkage mainly towards the mediastinum and the apices with distortion and atypical distribution of pulmonary vasculature and compensatory hyperinflation. Resolution in perivascular and peribronchial parts is often delayed and results in scarring. Interstitial pneumonia may result directly in pulmonary fibrosis with loss of volume and honeycombing. With varying microorganisms and varying immunity chronic and atypical courses are observed more frequently.
