Note is again made of the well marginated lobulated mass from the tip of the clivus down to the level of the dens, in keeping with known chordoma. Slightly more heterogeneous appearance on T2 and post contrast imaging with mild size reduction in keeping with surgery and radiotherapy since 6.2.13. The expansile component protruding into the right peri-medullary cistern again touches the right vertebral artery, but with preserved CSF space, and no definite increased involvement of the right hypoglossal canal.
