title: Cytologic and histologic features of a poorly differentiated glioma in a dog.
abstract: A 5-year old female Boxer with a 1-week history of progressive paresis and paraplegia had a T10-13 subarachnoid filling defect on myelography. Exploratory hemilaminectomy revealed an intramedullary spinal cord tumor which was subsequently diagnosed as a poorly differentiated glioma, most likely an anaplastic ependymoma. The cytologic, histologic, and immunocytochemical staining characteristics of this neoplasm are described. Differential diagnoses, including primary and secondary tumors involving the central nervous system are discussed.
