Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal silhouette is prominent but stable . The cardiac silhouette is enlarged with prior coronary stenting noted . Calcification at the aortic knob is unchanged . A large bore left - sided central venous catheter is unchanged in position with the tip terminating in the right atrium . The pulmonary vasculature is prominent with mild interstitial pulmonary edema , slightly improved from ___ . There is increased right perihilar opacification from the most recent prior study also likely due to pulmonary edema . Streaky opacities at the bilateral lung bases most likely reflect atelectasis ; however , superimposed infection is not excluded in the appropriate clinical context . There is a small right pleural effusion . No pneumothorax detected . Radiopaque densities projecting over the left lateral lung base are likely external to the patient . There is no evidence of free air beneath the right hemidiaphragm .
    OUTPUT:
    
1 . Mild pulmonary edema . Increased opacification at the bilateral lung bases may be related in part to dependent pulmonary edema and atelectasis . 2 . No widening of the mediastinum . Stable cardiomegaly .
