Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal silhouette , including the markedly tortuous aorta , is unchanged . There is no CHF . A small right effusion is likely present , but is not clearly changed . Areas of pleural fluid seen on the lateral view do not appear increased in the interval . Prominent right hilum is better seen on the current examination . Known right lower lobe mass is not well delineated , but may correspond to the right infrahilar soft tissue fullness . There is an equivocal focal opacity along the mid right chest wall laterally , which appears new , and a possible vague opacity at the lung left lung base laterally , which also appears new . A left - sided indwelling catheter is again noted , with tip in right atrium .
    OUTPUT:
    
1 . No CHF or increase in previously seen pleural effusions to suggest volume overload . 2 . Equivocal new vague opacities in the right mid zone and left base laterally . These are of uncertain etiology , but given peripheral location , if real , raise the possibility of emboli . Attention to these areas on followup films recommended . Given the presence of dyspnea , further assessment with chest CTA could be considered . 3 . Otherwise , no focal infiltrate or opacity identified . 4 . Right - greater - than - left hilar prominence again noted . Known new right base mass not well depicted , but may correspond to the right infrahilar mass .
