    INPUT: The heart is at the upper limits of normal size . There is mild unfolding of the thoracic aorta with calcifications seen along the aortic arch . Otherwise , allowing for differences in technique , the mediastinal and hilar contours appear unchanged . There are patchy opacities in the right upper lobe as well as in the left lower lobe , worrisome for multifocal pneumonia . Areas of lung including the left upper lung appear spared without abnormality of the pulmonary vascularity . Minor degenerative changes are present .
    OUTPUT:
    
Findings suggestive of multifocal pneumonia in the appropriate clinical setting . Other etiologies such as aspiration could also be considered . Followup radiographs are recommended to show resolution in the short - term .
