    INPUT: A frontal upright view of the chest was obtained portably . The lungs are well expanded without dense consolidation , pleural effusion , or pneumothorax . Subtle opacity at the right lung base is likely crowding of vessels but may represent infection in the appropriate clinical setting . Heart size is normal . Mediastinal silhouette and hilar contours are normal . No acute osseous abnormality is identified . A left pectoral intracardiac device tip projects over the right ventricle . An LAD stent is in place . A 10 mm nodule over the right lung basemay be nipple .
    OUTPUT:
