Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior study the right internal jugular central venous line is been removed . Heart size appears normal and a tortuous aorta is again demonstrated . Opacification of the retrocardiac region is likely secondary to the known large hiatal hernia . Additional right lung base opacity could be from consolidation and a small pleural effusion . No evidence of pulmonary edema . Right shoulder arthroplasty appears unremarkable .
    OUTPUT:
    
New right lung base consolidation and costophrenic angle obscuration may reflect pneumonia and a small right pleural effusion .
