Optic Chiasm and Bilateral Optic Nerve Oligodendroglioma in A 29‐Month‐Old German Shepherd

The tumor's localization and histological characteristics suggested a primary origin within the optic pathway, differing from typical canine oligodendrogliomas. This case emphasizes the rarity of canine optic pathway oligodendrogliomas, a diagnosis that is similarly uncommon in human medicine. Dogs have been proposed as an intermediate animal model for human gliomas, and this case underscores the need for further molecular characterization of canine gliomas to improve diagnostic accuracy, therapeutic strategies, and comparative oncology insights.
