Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided catheter is present . It probably overlies the mid / distal SVC . No pneumothorax is detected . There is probable background hyperinflation / COPD . There is probable mild cardiomegaly . The mediastinum is slightly prominent , with convexity in the AP window , consistent with known mediastinal lymphadenopathy . The hila are not obviously enlarged . There are increased interstitial markings diffusely , with peribronchial cuffing and thickening of the minor fissure . There is only slight upper zone redistribution . A lateral view shows very small posterior pleural effusions . There are patchy bibasilar opacities more pronounced on the left .
    OUTPUT:
    
1 . Somewhat atypical course to the right sided line , though it is probably overlies the SVC . Clinical correlation requested . No pneumothorax detected . 2 . Probable background COPD . 3 . Mild cardiomegaly . Findings consistent with known mediastinal lymphadenopathy . 4 . Diffusely increased interstitial markings . This does not necessarily relate to CHF and , depending on the clinical setting , other causes of diffusely increased interstitial markings should be considered . 5 . Patchy bibasilar opacities , which may reflect collapse and / or consolidation , but should also be considered in the full clinical context . 6 . Aside from placement of the catheter , no definite change compared with outside film from ___
