Bilateral nipple densities are visualized . No airspace consolidation . The previously noted nodular density on the lateral radiograph just anterior to the proximal descending thoracic aorta is no longer visualized and was most likely composite in nature . Round metallic density seen in the upper abdomen just anterior to the spine is of indeterminate etiology and is seen on radiographs since ___ .
    OUTPUT:
