Figure 2. Chest computed tomography (CT) at the patient’s first visit (A, B) showed a diffuse soft tissue mass-like lesion of the anterior mediastinum with severe stenosis of the superior vena cava (arrows) and right pulmonary artery (arrowhead). (C, D) CT at 1 week after the corticosteroid treatment. The size of the mediastinal mass-like lesion was mildly reduced, and the severe stenosis of the superior vena cava (allows) and right pulmonary artery (arrowhead) was slightly mitigated.
