Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable view of the chest . Exam is limited due to portable technique and respiratory motion . There is however left basilar opacity which silhouettes the hemidiaphragm . Cardiac silhouette is enlarged likely due to a combination of cardiomegaly and accentuation from technique . Superiorly the lungs are clear and there is no definite right basilar opacity . Hypertrophic changes are noted in the spine . Possible surgical clips project over the left lower chest .
    OUTPUT:
    
Left basilar opacity likely due to some combination of pleural effusion with possible underlying atelectasis or consolidation , potentially infection . PA and lateral may help evaluate if patient is amenable . Cardiomegaly likely exaggerated by AP technique .
