    INPUT: PA and lateral chest radiographs are obtained with the patient in the upright position . Heart size is stable . Mediastinal contours are unremarkable . Coarse opacifications seen previously at the right base are relatively unchanged . Persistent bibasilar atelectasis . Stable small right pleural effusion . Small left pleural effusion has increased in size . Increased density of left lung opacifications is consistent with consolidation . No pulmonary vascular congestion . No pneumothorax .
    OUTPUT:
    
1 . Increased opacification of the left lower lobe is consistent with consolidation and pneumonia should be considered in the appropriate clinical context . 2 . Increased small left pleural effusion .
