    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding portable AP chest examination of ___ . Bilateral pleural effusions obscured the lung bases , more on the right than the left . Heart contours are obscured , but previously described cardiac enlargement persists as there is continuous perivascular haze in the accessible pulmonary vasculature . There are bilateral linear densities in the lung structures indicative of bilateral plate atelectasis coinciding with the pleural effusions . It is impossible to identify new pulmonary inflammatory processes , but large new parenchymal infiltrates can not be identified . There is no pneumothorax . The pleural effusions are prominently located in posterior pleural spaces as identified on the lateral view .
