    INPUT: Frontal and lateral chest radiographdemonstrates moderately well expanded lungs . A 0 .8 x 0 .4 cm left apical opacity projecting over anterior portion of left first rib is worrisome for a pulmonary nodule . Right lung is clear . No pleural effusion or pneumothorax . Heart size , mediastinal contour , and hila are unremarkable . Limited assessment of the upper abdomen is within normal limits . No displaced rib or clavicular fracture .
    OUTPUT:
    
1 . Possible 0 .8 cm left apical pulmonary nodule . Recommend lordotic view radiograph to assess whether true pulmonary nodule versus sclerotic osseous focus in rib . 2 . Although no fracture or other bone abnormality is seen , conventional chest radiographs are not appropriate for detection or characterization of chest cage lesions . Any focal findings should be clearly marked and imaged with either bone detail views or CT scanning .
