Allowing for differences in positioning , the cardiomediastinal silhouette is probably unchanged . The mean pulmonary artery and hila both . prominent , similar to the prior film . Again seen is increased retrocardiac opacity , consistent with left lower lobe collapse and / or consolidation . There is diffuse vascular plethora , thickening of the minor fissure and peribronchial cuffing . Hazy opacity at both lung bases could reflect atelectasis and / or small amount of layering pleural fluid . Compared with the prior film and allowing for technical differences , the overall appearance is similar .
