    INPUT: There is a dual - lumen dialysis catheter terminating in the lower superior vena cava . The cardiac , mediastinal and hilar contours appear unchanged . There is again moderate cardiomegaly . The aortic arch is partly calcified . There is no pleural effusion or pneumothorax . There is similar patchy opacification of the left cardiophrenic angle and projecting over the posterior lower lobes on the lateral view , but there is no evidence for acute superimposed opacification . Left basilar and posterior opacities are probably due to minor atelectasis or scarring . The osseous structures are unremarkable .

Stable appearance of the chest with no evidence of acute disease .
