Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-upright position . Heart size is borderline , without typical configurational abnormality . Thoracic aorta of normal ___ but with some calcium deposits in the wall at the level of the arch . There is some moderate degree of perivascular haze in the pulmonary circulation , but there is no conclusive finding for central parenchymal or basal interstitial pulmonary edema . Diffuse haze is overlying the lower half of the right hemithorax in the absence of any pleural fluid accumulation blunting the lateral pleural sinuses . Considering patient 's significant recumbent position , it is possible that this haze relates to pleural effusion layering in the posterior pleural compartment . In the differential diagnosis , this density could of course also represent parenchymal infiltrates of inflammatory nature . Review of the latest transferred chest examination from ___ dated ___ demonstrated similar findings .
    OUTPUT:
    
Questionable right - sided pleural effusion or parenchymal infiltrates in right lower lobe , difficult to differentiate on single portable chest view . Recommended additional lateral view or new evaluation with chest CT .
