Coronal (A) and axial (B) CT images of the cervical spine demonstrate osteochondroma (arrow) arising from the left C2 lamina and projecting into the spinal canal. 3D reconstructed image (C) demonstrates the osseous outgrowth projecting superiorly towards the dens (arrow).

A stat CT exam of the cervical spine demonstrated an osseous outgrowth from the left C2 lamina projecting into the spinal canal, directed superiorly towards the dens (Fig. 1).
Sagittal STIR (A, TR 2000 and TE 22) and T2 (B, TR 4000 and TE 108) MR images of the cervical spine demonstrate osteochondroma (arrow) arising from the left C2 lamina and compressing the spinal cord. The lesion is continuous with the cortex and medullary cavity of the C2 lamina.

Subsequent MRI of the cervical spine showed a compressive effect on the spinal cord (Fig. 2).
Cross table lateral radiograph of the cervical spine demonstrates osteochondroma (arrow) arising from the left C2 lamina and projecting into the spinal canal.
