Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes . There are multiple cavitating lesions slightly obscured by superimposed interstitial edema and are better seen on prior radiographs and CT . Interval increase in interstitial edema , however this can be exaggerated by low lung volumes . Mild platelike atelectasis in the right mid lung . The cardiomediastinal and hilar contours are stable . The small right pleural effusion has increased in the interval . The remaining pleural surfaces are normal . The left PICC line terminates in the mid to lower SVC .
    OUTPUT:
    
Interval worsening of interstitial edema and small right pleural effusion . Septic emboli better evaluated on prior imaging .
