Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A new right internal jugular central venous catheter terminates likely at the origin of the SVC . There is no pneumothorax . In the interim since the prior study , performed approximately four hours earlier , there has been a significant increase in the size of the right - sided pleural effusion , which now layers across the entire right hemithorax . There is probably a left - sided smaller pleural effusion . Heart size is markedly enlarged , a chronic finding since as far back as ___ .
    OUTPUT:
    
1 . Right internal jugular central venous catheter , likely terminates in the extreme upper SVC . 2 . Marked increase in the size of the right - sided pleural effusion since the prior study 4 hours earlier . 3 . Chronic cardiomegaly , given the patient 's young age , correlate with history of congenital heart disease . Evaluation with echocardiogram should be considered . This would also serve the function of ruling out pericardial effusion . 4 . Given the bilateral pleural effusions , underlying infection can not be ruled out , especially in the bases .
