    INPUT: AP single view of the chest obtained with patient in semi-upright position . Analysis is performed in direct comparison with the next preceding similar study of ___ . The predescribed internal jugular vein approach wide bore catheter remains in unchanged position , terminating overlying the right atrium . High - positioned diaphragms as before conceal major portion of the heart shadow , but marked cardiac enlargement is unlikely . The previously described bilateral basal atelectatic and inflammatory lung changes are improved on the left side , but remain more on the right base where they still conceal the diaphragmatic contours . New parenchymal infiltrate occupies now diffusely the right upper lobe area , terminating the site of the right - sided minor fissure . This infiltrate was not present on the preceding examination of ___ . Differentiation between fungal and bacterial process exceeds possibilities on portable single view chest examination . No pneumothorax is identified .
    OUTPUT:
    
New diffuse hazy infiltrate occupying right upper lobe area , probably of infectious genesis .
