Meningioma in Cats

Meningioma, the most common brain tumor found in cats, is a tumor affecting the meninges, the system of membranes that envelops the central nervous system. All breeds of cats are at risk of meningioma, and it is usually seen in cats older than nine years of age.

Symptoms and Types

The symptoms vary depending upon the location of tumor, but some of the more common symptoms include:

• Seizures (more common in dogs)
• Visual deficits
• Abnormal behavior or mental state
• Uncoordinated movements
• Neck or back pain

Causes

The underlying cause for meningioma is currently unknown.

Diagnosis

You will need to give a thorough history of your cat’s health, including the onset and nature of the symptoms, to your veterinarian. He or she will then perform a complete physical examination as well as a biochemistry profile, urinalysis, and complete blood count -- the results of which are typically normal. For further analysis, your cat’s veterinarian will also take a sample of cerebrospinal fluid, a protective and nourishing fluid that circulates around the brain and spinal cord.

Magnetic Resonance Imaging and Computed Tomography scan are the two most valuable tools for identification of lesions and its localization. Although tissue biopsies are also frequently used to diagnose meningioma.
