Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The lung bases are somewhat underpenetrated due to patient body habitus . The patient is rotated somewhat to the left . The cardiomediastinal silhouette is difficult to accurately assess . There are perihilar opacities bilaterally which may be due to edema . If there is concern for underlying acute mediastinal process , chest CT is more sensitive . There may be trace pleural effusions . Underlying basilar consolidation is difficult to exclude . The cardiac silhouette is enlarged .
    OUTPUT:
    
Underpenetration of the lung bases , particularly the left lung base likely due to patient body habitus . The cardiomediastinal silhouette is likely enlarged and if there is concern for acute mediastinal process , chest CT is more sensitive . Perihilar opacities are likely due to pulmonary edema ; however , underlying infectious process is not excluded . Possible trace pleural effusions .
