Intraspinal neoplasia in the dog is relatively rare and may be classified according to the location of the tumor. Extradural tumors are situated outside the dura mater. Intradural tumors may be subdivided into two classes, depending upon whether the tumor is located outside the spinal cord in the subdural space (intradural extramedullary) or within the spinal cord substance (intramedullary). Intramedullary tumors are the least commonly reported spinal cord tumors; most primary intramedullary tumors are astrocytomas, ependymomas, or oligodendrogliomas. Reported here are the clinical, radiographic, and pathological findings associated with a spinal cord oligodendroglioma in a dog.
