Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Positioning on the lateral view is limited by slight rotation . Allowing for this , minimal patchy opacity at the left base likely represents atelectasis . An early infiltrate is considered much less likely . The lungs are otherwise grossly clear , without focal infiltrate , consolidation , or effusion . Heart size is at the upper limits of normal . The aorta is unfolded . No CHF is detected . Within the limits of plain film radiography , no hilar or mediastinal lymphadenopathy is detected . A small ( 7 mm ) ovoid density projecting over the right scapula near the coracoid process could represent a small loose body or focus of hydroxyapatite .
    OUTPUT:
    
No convincing infectious infiltrate identified . Minimal patchy opacity at the left base is non-specific and could represent minimal atelectasis . Otherwise , no evidence of acute pulmonary process .
