However , there are also increased opacities at the right perihilar and right infrahilar / right basilar regions , right greater than left , which could relate to fluid overload ; however , superimposed multifocal infectious process is not excluded . No large pleural effusion is seen . There is no evidence of pneumothorax . The cardiac silhouette is enlarged . There appears to be mild prominence of the main pulmonary artery which may be due to a component of underlying pulmonary hypertension . The aortic knob is calcified .
