case_images: The CT showed lamellar density shadow of middle and posterior mediastinum at the size of 10.6*8.9 cm, and no obvious enhancement was found in enhanced CT (Figure 1A). The left main bronchus and descending aorta were oppressed and displaced, accompanied by the compression of the left lower lobar bronchus (Figure 1A). Unfortunately, a left mediastinal mass was observed in the chest CT 12 months after surgery, which showed a little fat density shadow in the middle mediastinum at the size of 9.7*6.6*11.9 cm (Figure 1B).
