T2-weighted sagittal (a, c) and transverse (b, d) MR-images. a There is a deviation of the Th8–Th9 vertebral arch that protrudes ventrally into the vertebral canal. There is loss of visualization of the epidural fat and CSF column dorsally and hyperintense intramedullary signal (red arrow); b there is a large bone mass causing severe extradural dorsal right compression of the spinal cord at the level of the Th8–Th9 intervertebral space (red arrow); c visible hyperintense intramedullary signal between the L2–L3 intervertebral spaces (red arrow); d a large bone mass causing severe extradural right compression of the spinal cord at the level of L2–L3 intervertebral space (red arrow)
