    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There is no pleural effusion or pneumothorax . Surgical clips project over the right axilla . A nipple shadow is visualized on the right side . In addition to the nipple shadow , there is a small nodular density projecting along the lateral right mid chest , for which aritfact versus true pulmonary nodule ( but not apparent before ) is questioned . Patchy vascular calcifications are noted along the upper abdominal aorta . Bony structures appear unchanged including slight loss among lower thoracic vertebral body heights , which appears chronic .
    OUTPUT:
    
No evidence of acute disease . Possible lung nodule on the right ; particularly given the history of malignancy , chest CT is recommended when clinically appropriate to evaluate further . A preliminary reading was provided by electronic means while the patient was still in the ER .
