Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided AICD / pacemaker device is noted with single lead terminating in the right ventricle , unchanged . Moderate cardiomegaly is re- demonstrated , and the mediastinal and hilar contours are stable . Aortic knob calcifications are again demonstrated . There is no pulmonary vascular congestion . No focal consolidation or pneumothorax is present . 1 cm nodular opacity is seen projecting over the right mid lung field , specifically over the right ___ posterior rib , not clearly demonstrated on the prior exams . Blunting of the costophrenic angles posteriorly on the lateral view suggest trace bilateral pleural effusions . No acute osseous abnormality is identified .
    OUTPUT:
    
1 . Trace bilateral pleural effusions , but no overt pulmonary edema . 2 . Rounded 1 centimeter opacity projecting over the right mid lung field appears new compared to the prior study . The finding is not well localized on the lateral view , but nevertheless , this could reflect a nodular parenchymal process such as an inflammatory or infectious process . Followup radiographs are recommended including oblique views for further assessment .
