The size of the tumor was 5.5×6 cm. Most of the edges were smooth, and part of the intervertebral foramen broke into the spinal canal, and the vertebrae were seen to be destroyed. Mass enhancement was evident. After the enhancement, the CT value was 100-120 Hu, and it was seen to be gradually smaller and communicated with the left atrium.
