Description
Summary:A 63-year-old, previously healthy man presented with a rare large intradural retroclival chordoma without bone involvement. Computed tomography showed that the tumor was completely intradural and did not involve the bone, as confirmed at intraoperative inspection. The tumor was totally excised via the anterior transpetrosal approach. Surgery is the most effective first-line treatment for patients with chordoma despite the typical extradural extension and bone destruction. Complete resection is feasible for intradural extraosseous chordoma because of the sharply circumscribed margins and absence of bone involvement. Specialized skull base techniques should be used instead of conventional surgical approaches for intradural skull base chordoma.
