    INPUT: Frontal and lateral chest radiographs were obtained . There is a new mass - like consolidation which originates from the left hilum and extends into the left upper lobe . There is associated mild upper lobe volume loss , manifested by mild leftward tracheal deviation , upward displacement of the left hilum , and slight tenting of the left hemidiaphragm . There is also some mild streaky atelectasis in the left lower lobe . The right lung is essentially clear . No pleural effusion , pneumothorax , or pulmonary edema is seen . A small granuloma is again visualized in the right lung overlying the fifth posterior rib laterally . The heart size is normal . There is a small hiatal hernia , unchanged from prior study .
    OUTPUT:
