    INPUT: Frontal lateral chest radiographs demonstrate a normal cardiomediastinal silhouette , with prominent epicardial fat overlying the right cardiophrenic angle , as seen on multiple prior exams . The lungs are fairly well - aerated . Streaky increased opacity in the right lung base likely represents atelectasis , but an early pneumonia can not be excluded . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Streaky increased opacity in the right lung base likely represents atelectasis , but an early pneumonia can not be excluded , and short - term followup radiographs may be helpful in this regard if warranted clinically .
