Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The mediastinal and hilar contours are unremarkable . Streaky medial right lower lung opacity suggests minor atelectasis . Otherwise , the lungs appear clear . There are no pleural effusions or pneumothorax . Along the mid thoracic spine , there is a mild wedge compression deformity , which is age - indeterminate and not necessarily recent but somewhat unusual in this age group .
    OUTPUT:
    
Mild mid thoracic wedge compression deformity , indeterminate as to age and not fully characterized , although possible due to an older injury . Further investigation could be considered with CT , however , if focal findings suggest that it may potentially represent an acute process ; correlation with physical findings and any history of prior trauma is recommended .
