Embryological Considerations A developmental lesion related to chordoma is the ecchordosis physaliphora. Cranial nerve examination revealed no gag reflex, uvula deviation to left side, decreased hearing acuity on right ear, decreased taste on right side of tongue and numbness on right V1, V2 dermatome.


Preoperative hearing threshold was 90 dB on the right and 45 dB on the left side by brainstem auditory evoked potential BAEPand it was improved to 35 dB on the right and 30 dB on the left side by BAEP studied on 11th postoperative day. The cordona in such cases is poor. Histological, immunocytochemical, and ultrastructural studies confirmed dep diagnosis of chordoma Figs.

We achieved near total resection of intradural chordoma and adjuvant gamma knife radiosurgery was performed for remnant tumor at 1 month after surgery. Surgical experience and review of the literature. Some areas of tumor was attached to right trigeminal nerve and located near the right facial and vestibulocochlear nerve complex. Postoperative course The patient complained dizziness, but other symptoms, such as ataxia, right facial numbness without paralysis, right hearing disturbance, were much more improved.

The interest of this case lies not only in the nature and location of the incidentally discovered tumor but also codoma its radiological presentation as an asymptomatic lesion at one lumbar level associated with a symptomatic disc extrusion at another lumbar level.
