[A case of intramedullary cervical metastasis from cerebellar anaplastic oligodendroglioma without typical MR appearance for CSF dissemination].
We report a case of intramedullary cervical metastasis from cerebellar anaplastic oligodendroglioma without any MR appearance for CSF dissemination or recurrence in the primary tumor site. The case was a 73-year-old female who underwent tumor resection for cerebellar anaplastic oligodendroglioma following irradiation and TMZ chemotherapy. One year and a half later, a small nodular lesion developed at the temporal lobe. While treatment with TMZ was restarted during the course, another intramedullary cervical lesion produced additionally without any CSF dissemination or recurrence at the primary site. The histological examination obtained in spinal surgery revealed evidence of similar features consistent with a previous cerebellar tumor with anaplastic oligodendroglioma. Although CSF dissemination by malignant glioma with leptomeningeal enhancement is relatively well recognized at their terminal stage, cases with intramedullary cervical metastasis without any leptomeningeal enhancement have only been rarely described. We discussed the mechanisms of intramedullary cervical metastasis from intracranial malignant glioma.
