Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest demonstrates unchanged position of right subclavian approach central venous catheter and apparently abandoned left approach central line tubing . The heart is top normal in size . The mediastinal and hilar contours are within normal limits allowing for rotation . Dense consolidation in the left upper lobe is progressively more dense as compared to prior exams , most compatible with pneumonia . A slightly less dense consolidation is likely present in the right lower lobe . Underlying lesion in the left upper lung can not be assessed . Streaky bibasilar subsegmental atelectasis is present . There is a similar to slightly increased degree of central pulmonary vascular congestion . There is no large pleural effusion or pneumothorax .
    OUTPUT:
    
Confluent consolidation in the left upper lobe and likely additional focus of consolidation in the right lower lobe , suggestive of multifocal pneumonia . Recommend treatment and followup to resolution to exclude underlying lesion .
