    INPUT: A left mid lung mass with a clip is reidentified with associated thoracotomy changes . In the background of diffuse bilateral interstitial thickening , there are areas of ill defined patchy opacities in the right lower lung . Obscuration of the margin of the left hemidiaphragm suggests left lower lobe consolidation . A spine sign as well as patchy opacities in the posterior costophrenic sulci are seen in the lateral view . Mild cardiomegaly is unchanged . There might be a small left sided effusion .
    OUTPUT:
    
1 . Ill defined patchy opacities in both lung bases are compatible with pneumonia on the background of interstitial pulmonary edema . 2 . Unchanged appearance of left mid lung mass with thoracotomy changes in the left lateral ribs .
