case_images: The lesion presented as a crescent shape along the spinal dura mater and had a well-defined border along the vertebral arch (Figure 1).
case_images: Preoperative MR imaging of the cervical spine. The lesion shows hypointensity on both (a) T2 and (b) T1 weighted images which causes spinal canal stenosis. (c) Sagittal post-contrast T1 weighted imaging demonstrates heterogeneous enhancement.
