Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest provided . Lung volumes are low limiting assessment . The hila appear somewhat prominent and hilar congestion difficult to exclude . There is a subtle nodular opacity projecting over the right upper lung which may represent confluence of shadows though the possibility of a pulmonary nodule or a a focal consolidation is difficult to exclude in the correct clinical setting . No large effusion is seen . No pneumothorax . Heart size is normal . Mediastinal contour is unremarkable . Bony structures appear intact .
    OUTPUT:
    
1 . Nodular opacity projecting over the right upper lung , question confluence of shadows , may be resolves with dedicated PA and lateral possibly with oblique projections . 2 . Hilar prominence may reflect central congestion versus nodal prominence . Please correlate clinically .
