Your dog was diagnosed with Intracranial Meningioma. Most common primary intracranial tumour in dogs. Typically extra-axial, potentially resectable depending on location. Some studies suggest dolichocephalic breeds may be predisposed, though this association is less firmly established than the brachycephalic predisposition for gliomas. Often discovered when neurological signs develop (seizures, behavioural changes, circling). Compare 4 treatment options for dogs including Surgical Resection (Craniotomy), Radiation Therapy (Definitive or Stereotactic), Surgery + Post-Operative Radiation — with survival times, costs, and what to expect during treatment.

About This Cancer
Meningioma is the most common primary brain tumour in dogs, arising from the meninges — the protective membranes that surround the brain and spinal cord. Because these tumours grow on the surface of the brain (extra-axial) rather than within the brain tissue itself, they often push against the brain rather than invading it, which means they can potentially be surgically removed. Dogs typically present with neurological signs such as seizures, behavioural changes, circling, vision loss, or imbalance, depending on the tumour's location. Meningiomas are generally slow-growing, and many dogs respond well to surgery, radiation, or a combination, with survival times of one to several years. Golden Retrievers, Boxers, and Miniature Schnauzers appear to be at higher risk, and the tumour is most commonly diagnosed in middle-aged to older dogs.

Median Survival Time Comparison
How long the average patient survives with each treatment
Each treatment is rated by how much published research supports its use. Solid bars indicate stronger evidence; dashed bars mean less certainty.
Please note: All treatment data is sourced from published peer-reviewed literature. Survival times and cost figures are approximate guides. Your pet's individual factors — including tumour grade, stage, and overall health — will influence outcomes and should guide all treatment decisions. The strength-of-evidence rating reflects how much research exists, not how strongly a treatment is recommended. This tool is designed to help you have informed conversations with your veterinary oncologist, not to replace them. Costs shown are US referral centre estimates and may vary significantly by region.
