Plain-English summary
A mongrel dog and a golden retriever were diagnosed with brain tumors: an ependymoma in the third ventricle and a meningioma in the olfactory bulb. The ependymoma showed lower blood flow and higher blood volume compared to normal brain tissue, while the meningioma had higher blood flow and volume. These findings suggest that advanced imaging techniques like perfusion CT could help veterinarians better understand and classify brain tumors in pets. Treatment options would depend on the specific diagnosis and could include surgery or other therapies.

Abstract
Brain perfusion computed tomography (CT) scanning was performed in a mongrel dog and a golden retriever that were diagnosed with third ventricular tumor and olfactory bulb tumor, respectively, by contrast-enhanced CT. The tumors were pathologically diagnosed as ependymoma and meningioma, respectively. Perfusion CT results revealed that the ependymoma in this study had a lower blood flow, higher blood volume, and greater transit time of blood than the adjacent brain tissue. Further, the meningioma in this study had a higher blood flow, higher blood volume, and greater transit time of blood than the adjacent brain tissue. Perfusion CT can potentially be used for the grading of brain tumors and narrowing differential diagnosis, provided the perfusion CT data of animals are accumulated.
