Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Overall , no significant interval change other than perhaps slight interval increase in left lower lobe atelectasis with left shift of the mediastinum . The known common tiny left apical pneumothorax persists , grossly unchanged in size since yesterday . The left PleurX catheter tip projects over the left lower thorax within the moderate - sized left pleural effusion , which is overall also similar in size . Associated compressive atelectasis persists . Opacity in left lateral lung , corresponding to the known malignancy is unchanged . Increased interstitial markings , particularly on the left are unchanged , reflecting edema and / or possible lymphangitic spread . No change in the radiographic appearance of the right lung . No right pleural effusion .
    OUTPUT:
    
1 . Persistent tiny left apical pneumothorax without evidence of tension . 2 . Persistent moderate left pleural effusion despite PleurX catheter placement . 3 . Slight interval increase in left lower lobe atelectasis .
