Figure 1 Preoperative imaging data of the patient:(A) Sagittal CT revealed a high-density mass protruding into the spinal canal at the levels of T8–T10, indicating potential spinal cord compression; (B) Preoperative sagittal X-ray of the patient; (C) The MRI plain scan revealed significant stenosis of the spinal canal at the corresponding levels of T8–T10, accompanied by marked compression and narrowing of the adjacent thoracic cord; (D–G) The coronal CT plain scan at T8–10 level revealed high-density ossification that had ruptured into the spinal canal, resulting in significant narrowing of the corresponding canal.
