Abstract

An 11-year-old spayed female French bulldog was referred on suspicion of nasal tumor. Anaplastic oligodendroglioma in the olfactory bulb that was suspected to have invaded the nasal cavity was diagnosed from imaging and histopathology. Metastasis to cervical lymph nodes was suspected, with no other metastases identified. The brain-to-nasal lesion and lymph nodes were treated with hypo-fractionated radiation therapy. Nasal congestion soon resolved. About 3 months later, follow-up computed tomography revealed multiple hepatic and splenic masses, which were cytologically suspected as metastatic oligodendroglioma. Nimustine, followed by toceranib phosphate, seemed to have no effect, and the dog died on day 167. Postmortem examination revealed the primary tumor disappearance and systemic metastases. Canine oligodendroglioma can grow outside the cranial vault, and systemically metastasize.
