Thoracic laminectomy and transpedicular vertebrectomy at T9 with spinal cord decompression and instrumentation causing an artefact on T1-weighted MRI (A, C) and on CT (B, D), sagittal and axial views. This 59-year-old male patient has esophageal adenocarcinoma metastatic to the T9 vertebra, involving the left side of the vertebral body, left pedicle, transverse process, and facets, and causing significant SCC with Bilsky grade 3 disease. He underwent T9 laminectomy and partial vertebrectomy for spinal cord decompression as well as posterior segmental stabilization from T7–T11 (A, B), with cement augmentation and bilateral pedicle screws placed at T7, T8, T10, and T11 (C, D)
