Spinal dissemination following operation on cerebral oligodendroglioma

This paper concerns two cases of cerebral oligodendroglioma (intraventricular in one case, right temporal in the other), with spinal dissemination (cervical and upper thoracic respectively), manifested clinically 2 years and 14 months respectively after removal of the cerebral tumour. Anatomical examination confirmed the diagnosis of disseminated oligodendroglioma in the leptomeninges in both cases and also in the parenchyma in the second case.
