    INPUT: Frontal and lateral views of the chest were obtained . Bilateral skin folds are seen . There is a subtle patchy lateral right base opacity which could be due to a small focus of infection . The remainder of the lung is clear . There is no pleural effusion or pneumothorax . The cardiac silhouette is top normal . The aorta is calcified and tortuous . Mediastinal contours are similar in appearance compared to the prior study . A small focus of the opacity in the lateral right lung base could be due to a small focus of infection or possibly a nipple shadow . Consider repeat with nipple markers for further evaluation .
    OUTPUT:
