Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The lungs are relatively hyperinflated , with flattening of the diaphragms , suggesting chronic obstructive pulmonary disease . There is likely mild pulmonary edema . No discrete focal consolidation is seen . There is no large pleural effusion , although trace pleural effusions would be difficult to exclude . The cardiac silhouette is mildly enlarged . The aortic knob is calcified . Projecting over the left upper hemithorax at the left upper lateral lung / scapula , there is an ill - defined 1 .2 - cm rounded opacity , difficult to discern whether pulmonary or potentially within the scapula .
    OUTPUT:
    
1 . Ill - defined 1 .2 - cm opacity projecting over the left upper hemithorax , difficult to discern whether pulmonary or within the scapula . Recommend either shallow oblique views or chest CT for further evaluation to assess for a possible underlying pulmonary lesion .
