case_images: The MR revealed an expansile lesion involving the C2 vertebral body; the tumor infiltrated the laminae, pedicles, transverse processes, and spinous process [Figure 2].
case_images: (a) Histopathology shows densely cellular tumor consisting of small round cells with clear cytoplasm. (b) Immunohistochemistry shows positivity for vimentin-clone V9 and CD99 MIC2-clone 12E7.

case_images: The final histopathology showed a densely cellular tumor consisting of small round cells with clear cytoplasm [Figure 3a]. The immunohistochemistry showed that the tumor was strong positivity for vimentin-clone V9 and CD99 MIC2- clone 12E7 [Figure 3b]; these findings were consistent with the diagnosis of Ewing's sarcoma.
case_images: One year post operative radiograph shows well maintained sagittal alignment with implant in situ.
