A malignant oligodendroglioma of the right hypothalamus region occurred in a 9-year-old male dog (Yorkshire terrier, 4.7 kg). The tumor mass was soft and gelatinous. Histological examination revealed a honeycomb appearance and a perinuclear halo with many mitotic figures. Much vasoproliferation with extensive necrosis and calcification was observed in the parenchyma. Pathological findings in this case of canine oligodendroglioma coincided well with computed tomography and magnetic resonance imaging.
