    INPUT: The heart size is within normal limits . The mediastinal contours demonstrate a tortuous aorta that follows the contour of the S - shaped scoliosis of the thoracolumbar spine . The lungs demonstrate no lobar consolidation , but are similar in appearance to prior exam in which subtle basal opacities were though to reflect components of atelectasis or viral / atypical infection . There is no large pleural effusion or pneumothorax . Of note , the right humeral head is low - lying -- this appears chronic --?? subluxation .
    OUTPUT:
    
1 . No lobar consolidation to suggest bacterial pneumonia . As describe on prior report , subtle bibasilar opacities may represent viral / atypical infection ; followup imaging is recommended after therapy to document resolution . 2 . Apparent right glenohumeral joint subluxation . Correlate for pain .
