    Abstract:
    A 7-year-old male castrated Yorkshire Terrier dog developed slowly progressive neurologic disturbances consisting of difficulties in moving the neck, lack of proprioception, and tetraparesis 4 months prior its death. Neurologic examination, computer tomography, and myelography resulted in the tentative diagnosis of intramedullary cervicothoracic spinal cord lesion. At necropsy, an intramedullary cervical spinal cord mass between C5 and C6 was noticed. Histologically, cells of this well-demarcated, nonencapsulated neoplasm were arranged in sheaths or cords separated by a fine fibrovascular stroma. The polygonal to round tumor cells were characterized by moderate pale, basophilic, and vacuolar cytoplasm and round to slightly oval, centrally located nuclei with fine-stippled heterochromatin, a single nucleolus, and a very low mitotic activity. Tumor cells lacked glial fibrillary acidic protein, vimentin, factor VIII-related, and cytokeratin antigen expression. Histologic and immunohistochemical findings led to the diagnosis of a cervical spinal cord oligodendroglioma.
