Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest radiograph demonstrate moderate cardiomegaly . There is no pulmonary edema . There is no pneumothorax or pleural effusion . A 1 .1 x 1 .6 cm well - circumscribed oval opacity within the right upper lung zone peripherally appears calcified , no correlate on the lateral chest radiograph . Unclear if this is within the lung parenchyma or alternatively to the overlying soft tissues . Streaky opacity at the left lung base likely reflects atelectasis . No opacity convincing for pneumonia is seen . Surgical clips project over the subcutaneous tissues of the arm on the lateral view .
    OUTPUT:
    
1 . Moderate cardiomegaly without pulmonary edema . 2 . Oval apparently calcified opacity projecting over the right upper lung zone on the frontal view is without a correlate on the lateral view . Unclear if within the lung parenchyma . Additional oblique views would be helpful for localization .
