Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding portable chest examination of ___ . The previously documented successful right - sided thoracocentesis persists and there is no evidence of significant reaccumulation of the right - sided pleural effusion . There exist some increased linear vascular pattern on the right lung base , most likely representing interstitial edema . There is no evidence of new acute pulmonary parenchymal infiltrates and no pneumothorax is seen in the apical area . Findings in the left hemithorax are rather unchanged with obliteration of the left - sided diaphragmatic contour with blunting of the left lateral pleural sinus . The lateral view demonstrates the presence of a left - sided pleural effusion obliterating the entire posterior pleural sinus up to the level of the hila . An estimate suggests volume of about 1 liter . There is no evidence of new pulmonary parenchymal infiltrates and no pneumothorax is noted on either side . Cardiac enlargement is obvious . The appearance of the generally widened aorta with advanced wall calcifications appears unchanged .
    OUTPUT:
    
No reoccurrence of pleural effusion following right - sided thoracocentesis . Significant amount of pleural effusion exists also on the left side . Consider left sided thoracentese as well .
