    INPUT: Permanent pacemaker is present with leads overlying the right atrium and right ventricle . The right ventricular lead has an unusual cephalad course of the distal tip . Cardiac silhouette is upper limits of normal in size , and pulmonary vascularity is normal . Moderate elevation of the right hemidiaphragm is unchanged since the prior study , and is associated with adjacent basilar atelectasis . Focal atelectasis is also present at the left lung base . Small right pleural effusion is present , and has also been documented on recent abdominal CT of ___ .
    OUTPUT:
    
Small right pleural effusion . Linear opacities at both lung bases favor atelectasis over infectious pneumonia , but followup radiographs may be helpful to exclude early infectious consolidation given clinical suspicion for this entity .
