    INPUT: A single portable AP semi-erect view of the chest was obtained . Elevation of the right hemidiaphragm is chronic . Low lung volumes accentuate the pulmonary vasculature . There is no pulmonary edema . Allowing for low lung volumes , no definite focal consolidation or large effusion . Apparent enlargement of the cardiac silhouette is likely in part due to the portable technique and the low lung volumes . Mediastinal contour is grossly unremarkable . Linear basilar opacities likely represent atelectasis . A fracture is noted through the neck of the right humeral , which also demonstrates evidence of previous rotator cuff repair .
    OUTPUT:
    
1 ) Markedly low lung volumes without definite evidence of focal consolidation or pulmonary edema . Doubt CHF . 2 . Acute fracture of the right proximal humerus . ( Previously reported on shoulder xray exam from ___ .
