Presently , the heart size is normal . No configurational abnormality is present . Thoracic aorta and mediastinal structures are unremarkable . The pulmonary vasculature is not congested . Appearance of central pulmonary structures has not undergone any interval change in this patient with clinical history of sarcoidosis . When comparison is made with the next preceding chest examination of ___ , at that time identified linear opacities on the lung bases suggestive of peripheral atelectasis can not be identified anymore . No evidence of new infiltrates is presently found and the lateral and posterior pleural sinuses are free . Review of the chest examination of ___ , identify multiple bilateral , but mostly right - sided patchy infiltrates which on simultaneously performed chest CT demonstrated multiple peribronchial and perivascular ground - glass densities . These changes had regressed markedly on examination of ___ . On the present chest examination , no reoccurrence of such infiltrates can be observed .
    OUTPUT:
    
No evidence of new parenchymal infiltrates indicating acute pneumonia . Observed that the patient is very adipos , a factor , which reduces to some degree the ability of identifying hazy ground - glass densities .
