95. A 64-year-old man presents to the emergency department complaining of shortness of breath and facial swelling. He smokes one pack of cigarettes daily and has done so since the age of 16. On physical examination, he appears dyspneic at an angle of 45 degrees or less. His vital signs are as follows: heart rate 124 bpm, blood pressure 164/98 mmHg, respiratory rate 28 breaths/min, temperature 37.6°C (99.6°F), and oxygen saturation 89% on room air. Pulsus paradoxus is not present. His neck veins are dilated and do not collapse with inspiration. Collateral venous dilation is noted on the upper chest wall. There is facial edema and 1+ edema of the upper extremities bilaterally. Cyanosis is present. There is dullness to percussion and decreased breath sounds over the lower half of the right lung field. Given this clinical scenario, what would be the most likely finding on CT examination of the chest?
