    INPUT: PA and lateral views of the chest . There are low lung volumes . Within the right lung base adjacent to the heart border , there is a vague opacity that is new from prior study . This may represent atelectasis or pneumonia , however this may also represent crowding of the pulmonary vasculature due to low lung volumes . Likely small right pleural effusion . No pneumothorax . Heart size is normal . The mediastinal contours are normal . There is mild interstitial thickening and bronchial cuffing . There is a small nodular opacity projecting over the right lower hemithorax .
    OUTPUT:
    
1 . Right lung base opacity may represent atelectasis or pneumonia , recommend clinical correlation . This may also represent crowding of the vasculature due to low lung volumes . 2 . Likely small right pleural effusion . Mild interstitial thickening and bronchial cuffing . 3 . Small nodular opacity projecting over the right lower hemithorax . Recommend shallow oblique views with nipple markers for better assessment . Findings discussed with Dr . ___ by Dr . ___ at 8 :02 am on ___ by phone .
