Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The study is somewhat limited by patient body habitus . Lung volumes are low , resulting in bronchovascular crowding . Bilateral lower lobe opacities which have a somewhat linear component may represent atelectasis , but pneumonia is not completely excluded in the appropriate clinical setting . No other consolidation is seen . Small bilateral pleural effusions are noted . Heart size is normal . The mediastinal silhouette and hilar contours are normal allowing for low lung volumes . There is no pneumothorax . There is no free intraperitoneal air .
    OUTPUT:
    
Bilateral lower lobe opacities are likely atelectasis , but may represent pneumonia in the appropriate clinical setting . Small bilateral pleural effusions .
