There is a superimposed wedge - shaped consolidation in the left upper lung which is on a background of interstitial lung disease . Dense retrocardiac opacity is new over the interval , and may represent atelectasis or pheumonia , and / or hemorrhage . The cardiomediastinal contours are unchanged . The endotracheal tube ends 6 .2 cm from the carina . Right - sided internal jugular central venous line dense at the proximal SVC . There is no pneumothorax . There is a small left - sided pleural effusion .
