    INPUT: A nasogastric tube is seen coursing below the diaphragm with the tip and side port terminating in the left upper quadrant , likely within the stomach . Radiopaque densities projecting over the right upper quadrant are compatible with gallstones . Renally excreted contrast is partially imaged within the abdomen . Bilateral small - to - moderate pleural effusions are noted with underlying atelectasis or consolidation . The lung apices are not well evaluated on this lordotic view . Within this limitation , no significant pneumothorax is detected . The interstitial lung markings are slightly increased , but the pulmonary vasculature is not engorged . The cardiac silhouette is incompletely evaluated due to bilateral pleural effusions . The mediastinal contours are prominent on the right , corresponding to a known mediastinal mass . The thoracic aorta is tortuous .
    OUTPUT:
    
1 . NG tube in place . 2 . Bilateral small to moderate pleural effusions with underlying atelectasis or consolidation . 3 . Mediastinal widening corresponding to known mediastinal mass . 4 . Cholelithiasis .
