    INPUT: Cardiac silhouette remains enlarged . Asymmetrical biapical pleural and parenchymal opacification is unchanged since recent study of 1 day earlier , and is more prominent on the right than the left , with associated upper lobe volume loss . Nonspecific patchy bibasilar lung opacities are also unchanged .
    OUTPUT:
    
Persistent patchy bibasilar opacities , could potentially be due to pneumonia given the clinical suspicion for this entity . Bibasilar distribution suggests the possibility of aspiration . Asymmetrical right apical pleural and parenchymal opacities may potentially be due to asymmetrical scarring , but direct comparison to older radiographs of available would be helpful to exclude the possibility of a Pancoast tumor . In the absence of older studies for comparison , chest CT is recommended for further evaluation .
