A 12-year-old castrated male Miniature Schnauzer dog was presented with an acute seizure. On computed tomography, a mass was observed in the left nasal cavity and the lysis of the left cribriform plate was identified. Post-contrast magnetic resonance imaging showed a hyperintense mass in the left frontal lobe and hyperintense lesions in the left frontal sinus. The mass was tentatively diagnosed with a brain tumor secondary to a nasal tumor. Histopathology revealed that the mass was a nasal adenocarcinoma with invasion into the brain. This case report describes clinical, computed tomography, magnetic resonance imaging and histopathological findings of secondary intracranial tumor caused by extension of nasal adenocarcinoma in a dog. These findings may contribute to enhance the knowledge on secondary intracranial tumors in dogs.
