T2-weighted sagittal (a) and transverse (b, c) MR-images. a There is visible intramedullary signal between the Th8–Th9 and L2–L3 intervertebral space (red arrow). The remaining dorsal extradural compressions (red dot) are visible. They did not cause signs of pain during follow-up; b the large bone mass was removed at the level of the Th8–Th9 intervertebral space, resulting in spinal cord decompression. There is visible hyperintense intramedullary signal at this site (red arrow); c the large bone mass was removed at the level of the L2–L3 intervertebral space, showing lack of spinal cord compression (red arrow)
