Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest was obtained . Right - sided Port - A - Cath is again seen , terminating in the region of the distal SVC . There are low lung volumes . There is a linear left base opacity again seen , which most likely relates to atelectasis . There is new right base patchy opacity raising concern for infection although could also be due to aspiration . The left costophrenic angle is slightly blunted although to lesser extent than on the prior study . No large pleural effusion seen . The cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
1 . No large pleural effusion , minimal blunting of the left costophrenic angle , although to a lesser extent than on the prior study suggests interval decrease in left pleural effusion . 2 . Right lung base consolidation , new since prior , may be due to infection or aspiration . Left base atelectasis .
