Meningioma is a form of brain tumor that is found in dogs and cats. It is also the most common form found in both animals. In cats, these tumors usually develop after 10 years of age. Understanding symptoms of meningioma can help you get the best veterinary care as soon as possible.

Meningioma
-
The membranes that line the skull and the vertebral column are known as meninges. Meningioma is a tumor of these tissues. The term 'brain tumor' is inaccurate because these tumors can develop outside of the skull along the vertebra. Fortunately, meningiomas are benign and do not spread to other areas of the body (see Reference 1).
Seizures
-
Seizures occur in cats but they may not be as noticeable as with their canine counterparts. Seizures vary in severity, length or frequency of occurrence. They may not even be noted in the cat until the cat has been examined by a vet for other symptoms or conditions. Seizures can be treated with medicines like phenobarbital or potassium bromide (see Reference 1).
Abnormal Behavior
-
Many cats will exhibit strange or abnormal behavior. Some cats may walk in circles or appear to drag their toes. Other cats may walk with an altered gait. Pressure caused by the tumor on the nerves and brain will trigger these changes in behavior. The location of the tumor can also make some neurological symptoms more obvious than others (see References 1 and 2).
Vision
-
Depending on the location and severity of the meningioma, some cats may suffer partial to full blindness, which may be temporary or permanent (see Reference 1).
Treatment
-
Surgery is the best treatment option for meningioma. Because it grows around the outer layers of the brain and spinal cord, removal is exceptionally easy as compared to other tumors that can be further embedded in the brain tissue. In cats, meningioma tends to have a rubbery texture. This aids in its removal during surgery. Up to 70 percent of cats will live six months or more following the surgery (see References 1 and 2).
