case_images: (a) Plain radiographs of the cervical spine showing an osteolytic destruction of the C2 vertebral body with atlanto-axial instability (white arrow). (b,c) Sagital CT-median and paramedian images showing destruction of the body and pedicles of C2 vertebra (white arrows). (d) Sagital T2 MRI showed iso to hypointense signal at the site of bony defect with evidence of thecal sac compression (white arrow). (e,f) Note that the disc spaces are not involved. Dorsal spine sagittal T2 MRI sequence showing features of vertebra plana of the T9 vertebral body (black arrow) and lytic destruction of the left femoral head (black arrow).

case_images: Cervical spine X-rays revealed osteolytic destruction of the C2 body and atlantoaxial instability (AAI), while CT showed osteolytic destruction of the body/pedicles of C2 [Figures 1a-c]. MR imaging (MRI) showed that the marrow of C2 was replaced by a lesion which appeared isointense on T1 and iso-hypointense on T2 sequences that resulted in thecal sac compression [Figure 1d]. Imaging also revealed vertebra plana of the T9 with osteolytic destruction of the left femoral head [Figures 1e and f].
