T2-weighted cervical spine magnetic resonance imaging revealed C1-C2 compression (white arrow) in sagittal view (a) and medullary cord mass effect (white arrows) in axial view (b).

There are no intramedullary signal abnormalities. Computer tomography of the cervical spine demonstrated multiple lytic lesions extending from C1 to C7 vertebral bodies, but especially in the C1 and C2 vertebral bodies, leading to a deformation of the atlantoaxial junction [Figure 2]. The Spinal Instability Neoplastic Score (SINS) was evaluated at 15 [Table 1].

The size of the osteolytic process on C1 and C2 was decreased by 64% on a control MRI of the cervical spine [Figure 3].

Physical examination found a patient in apparent good health with no neurological deficit and was pain-free [Figure 4].
