    INPUT: The heart is moderately enlarged . The aortic arch is calcified . The mediastinal and hilar contours appear unchanged . The lung volumes are low . Calcified pleural plaques are present . There is no definite pleural effusion or pneumothorax . Band - like opacity in the left mid lung suggests minor atelectasis or scarring . Pulmonary vessels are somewhat engorged centrally suggesting pulmonary venous hypertension if not frank pulmonary edema . There is a confluent right basilar opacity worrisome for pneumonia .
    OUTPUT:
    
1 . Focal right basilar opacity worrisome for pneumonia . 2 . Mildly prominent pulmonary vasculature suggesting pulmonary venous hypertension , but not frank pulmonary edema . 3 . Moderate cardiomegaly . 4 . Calcified pleural plaques .
