Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . No definite focal consolidation is seen . There is eventration of the right hemidiaphragm . The right costophrenic angle is blunted on the frontal view ; however , not well substantiated on the lateral view and trace pleural effusion is not excluded , it is felt unlikely . The cardiac silhouette is top normal . The aorta is calcified . The patient is rotated somewhat to the left . A retrocardiac air - fluid level seen on the lateral view is most consistent with hiatal hernia . Degenerative changes are seen along the spine .
    OUTPUT:
    
Hiatal hernia . Slight blunting of the right costophrenic angle may relate to the eventration , though very trace right pleural effusion is not excluded . Otherwise , no acute cardiopulmonary process seen .
