Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Allowing for differences in technique , comparing with the prior scout view , the cardiac , mediastinal and hilar contours appear unchanged . Lungs are hyperinflated . There is no pleural effusion or pneumothorax . The lungs appear clear . Bones appear demineralized with mild - to - moderate degenerative changes and rightward convex curvature centered along the mid thoracic spine . Along the left upper lateral chest there are irregularities involving the lateral aspect of the descending upper left ribs concerning for one or more rib fractures , possibly involving the second through fourth ribs , although acuity is uncertain since old rib fractures were present on the left before .
    OUTPUT:
    
Suspected left upper lateral rib fractures , incompletely characterized and of uncertain acuity . Characterization with dedicated rib films or CT could be considered if more detailed assessment is needed clinically . Although old rib fractures were seen on the prior CT , these appear irregular and are not necessarily old based on the imaging findings . Correlation with physical findings is recommended .
