Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mild to moderately enlarged . The aortic arch is calcified . Mild perihilar fullness and upper zone redistribution of pulmonary vascularity suggests pulmonary venous hypertension without frank pulmonary edema . Projecting over the right mid - to - lower lung is a nodular focus , probably a nipple shadow , not discernable on the prior study . Relative increased density projecting over the left retrocardiac area is probably due to soft tissue attenuation . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Findings suggesting pulmonary venous hypertension without clear edema . Nodular focus projecting over the right mid lung , probably a nipple shadow . However , when clinically appropriate , confirmation using a repeat view with nipple markers is recommended .
