Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position , and analysis is made in direct comparison with the next preceding similar study of ___ . The heart size remains unchanged . The widespread chronic pulmonary changes including fibrosis , bronchiectasis and overlying infiltrates have not changed significantly during the latest four days examination interval . Comparison is therefore extended to the PA and lateral chest examination of ___ . It can be stated that some regress of hazy infiltrates in the right upper lobe area has occurred and also some scattered infiltrates in the right lower lobe area appear to have diminished . Left - sided changes again appear rather stable . Pulmonary congestive vascular pattern is difficult to assess in the presence of chronic interstitial disease and ectasia or it can be stated that no pleural effusion was present on examination of ___ . Comparison with chest examination of ___ , demonstrates the chronic pulmonary changes but markedly less extension of superimposed patchy parenchymal infiltrates .
    OUTPUT:
    
Enlarged heart size but stable . Advanced chronic interstitial pulmonary changes including airway distortions of ectatic - type , superimposed lateral parenchymal infiltrates that have not changed significantly during the latest examination interval . There is no radiographic evidence for acute pulmonary edema . No pleural effusion was seen , and no pneumothorax is present . Comparison chest examination of ___ , indicates that the patient has undergone a long - lasting episode of superimposed infectious processes .
