Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest PA and lateral radiograph demonstrates a markedly elevated right hemidiaphragm with adjacent compressive atelectasis or consolidation . Minimal blunting of the posterior costophrenic angle may indicate a small right pleural effusion . Left lung is clear . Cardiomediastinal borders are unremarkable .
    OUTPUT:
    
Right hemidiaphragm elevation with opacification posteriorly suggesting extensive adjacent lung atelectasis , though can not exclude developing infectious process . Possible right pleural effusion as well . If findings do not resolve on subsequent radiography , evaluation with chest CT could be considered , preferably with intravenous contrast if possible .
