    INPUT: A bedside AP radiograph of the chest demonstrates markedly low lung volumes with interval increase in the large left pleural effusion and left basilar atelectasis . There is pleural fluid tracking within the left major fissure . On the right , there is progressive elevation of the right hemidiaphragm consistent an intraabdominal process and basilar atelectasis . A heterogeneous opacity obscuring the right hemidiaphragmatic contour has been increasing since ___ . There is no pneumothorax . The pulmonary vascularity is normal and there is no edema . The right internal jugular central venous line likely terminates within the right atrium , and should be withdrawn at least 2 - 3 cm to ensure proper positioning in the lower SVC .
    OUTPUT:
    
1 . Enlarging large left pleural effusion and associated compressive atelectasis . 2 . Heterogeneous opacity in the right lower lobe concerning for developing pneumonia . 3 . Elevation of the right hemidiaphragm exacerbated by incomplete inspiration , likely secondary to an intra-abdominal process such as marked hepatomegaly or ascites . 4 . The right IJ central line should be withdrawn 2 - 3 cm to ensure placement in the lower SVC .
