A brain tumor is an abnormal growth of cells within the brain or its membranes (meninges). Common types include Meningiomas and Gliomas. These tumors compress healthy brain tissue, leading to neurological deficits, seizures, and behavioral changes.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpBrain tumors are not contagious. They arise from genetic mutations or spontaneous cellular changes. There is no known method of transmission between animals.
Symptoms typically begin subtly with behavioral changes or mild incoordination and progress to severe seizures, paralysis, blindness, or coma as the tumor grows and intracranial pressure increases.
Advanced imaging is required for a definitive diagnosis. Magnetic Resonance Imaging (MRI) is the gold standard for visualizing soft tissue of the brain. A CT scan may also be used. A biopsy is needed for specific tumor typing.
Treatment options include palliative care with corticosteroids (to reduce swelling) and anticonvulsants (for seizures). Specialized options include surgical removal or radiation therapy, available at referral centers.
There are no known preventative measures for primary brain tumors. General health maintenance and avoiding known carcinogens is recommended but not specific.
The prognosis is generally poor to guarded. With palliative care, survival is often measured in months. Surgery or radiation can extend quality life for a year or more depending on the tumor type.
