    INPUT: A right PICC is unchanged with the tip in the low SVC . Again , there is an opacity at the right base with elevation of the right hemidiaphragm , suggesting volume loss and atelectasis . A component of infection can not be completely excluded . Additionally , there is a small right pleural effusion . This is similar to the prior exam . The left lung is essentially clear . There is mild vascular congestion . No left pleural effusion or pneumothorax is identified . The cardiomediastinal silhouette is unchanged , with stable mild cardiomegaly .
    OUTPUT:
    
No significant change from the prior exam , including right basilar opacification , volume loss , and a small right pleural effusion . While the opacity and volume loss together suggest atelectasis , a component of infection can not be completely excluded .
