Gliomatosis cerebri (GC) is a rare, diffusely infiltrating, glial cell tumour of neuroepithelial origin. This report describes a case of oligodendroglial GC in a 6‐year‐old male Poodle with central nervous system symptoms. Computed tomography revealed anomalous parenchyma density and ventricular asymmetry. Cerebrospinal fluid showed elevated protein (30 mg dL −1 ) and nucleated cell count (20 µL −1 ). Presumptive diagnosis of necrotizing meningoencephalitis was made. Because of rapid deterioration of the general condition of the animal, the dog was euthanized. Histologically there was an infiltration of round or ovoid neoplastic cells in the white matter of the left cerebral hemisphere and in leptomeninges. Immunohistochemistry showed that 80% of the neoplastic cells expressed Olig2 and some 50% expressed glial fibrilary acidic protein. On the basis of clinical, histological and immunohistochemical features, a diagnosis of oligodendoglial GC was done. This case represents the first report of a case of oligodendroglial GC in the canid.
