Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy . The cardiac , mediastinal and hilar contours appear unchanged . The heart is at the upper limits of normal size . Patchy left lateral basilar opacities suggest minor atelectasis that is unchanged . There is a newly apparent round nodular opacity projecting over the right lung apex measuring about 7 mm in diameter . Although the area is difficult to evaluate due to overlapping bony structures , and it is known that scarring is present in the area from a prior CT of the cervical spine , the possibility of superimposed pulmonary nodule can not be excluded by this study . There is no pleural effusion or pneumothorax . Small osteophytes are similar along the thoracic spine .
    OUTPUT:
    
No evidence of acute disease . However , there is a newly apparent nodular focus projecting over the right lung apex , potentially a true pulmonary nodule , although a bone island or scarring depicted in a somewhat different fashion could potentially explain the finding . When clinically appropriate , chest CT is suggested to evaluate further in followup . An email regarding the findings and recommendations was sent to the ED QA nursing group on ___ .
