JAAHA – Canine Orbital Meningiomas
Can you name the most common type of brain tumor in dogs? What about humans? Believe it or not they are the same thing: Meningiomas. But a subset of this type of tumor is much less common.

Meningiomas are tumors that arise from the meninges, the protective membranes that cover the brain and spinal cord. These tumors are common in humans and in dogs; in fact, they account for 45% of all primary brain tumors in dogs.
However, the occurrence of these tumors in the orbital region of dogs (see image) is less common, accounting for about 3% of all canine meningiomas.
In a first-of-its-kind retrospective study in the Journal of the American Animal Hospital Association (JAAHA), a team of researchers evaluated surgery, radiation therapy, and survival in dogs with orbital meningiomas. The aim of the study was to determine the survivability of orbital meningiomas as compared to other types, such as those that affect the brain or spinal cord.
Read about what the team discovered in the article, “Treatment Outcomes of Canine Orbital Meningiomas in Seven Cases,” in the latest issue of JAAHA.
