Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes which accentuate the bronchovascular markings . Bibasilar atelectasis is seen . There is opacity at the medial right lung base which may represent confluence of vascular structures , but underlying consolidation is difficult to exclude . There is slight blunting of the costophrenic angles particularly on the right and a trace pleural effusion is also difficult to exclude . The cardiac and mediastinal silhouettes are stable . There is no evidence of pneumothorax .
    OUTPUT:
    
Low lung volumes accentuate the bronchovascular markings . Medial right base opacity may represent confluence of vascular structures given low lung volumes , although consolidation is not excluded in the appropriate clinical setting . Trace blunting of the right costophrenic angle which may be due to overlying soft tissue although trace pleural effusion is not excluded . Dedicated PA and lateral views would be helpful for further evaluation .
