Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to the prior study and allowing for differences in positioning , there is a small right to moderate pleural effusion which has probably increased in size , in with underlying atelectasis . There has been interval obscuration of the right hemidiaphragm . The right lung base catheter is again noted , though its relative position is difficult to evaluate . Increased retrocardiac density at the left base has increased , consistent with left lower lobe collapse and / or consolidation and small left effusion is also slightly larger . Doubt significant CHF . Cardiomediastinal silhouette is probably unchanged allowing for differences in positioning . Right upper quadrant TIPS catheter noted .
    OUTPUT:
    
1 . Probable interval increase in right pleural effusion and underlying atelectasis . Please see comment above . 2 . Increase in patchy opacity at left base , , consistent with left lower lobe collapse and / or consolidation , with newly visible small left pleural effusion .
