Gamma Knife radiosurgery has gained an important role to complete microsurgery to achieve long-term tumour control.
What is a meningioma?
Meningiomas are the most commonly found brain tumours, which are normally benign. Very rarely they can be malignant and can sometimes be found in multiple locations in the skull. Many of them are localised at the base of the skull.
What are the symptoms of a meningioma?
Meningiomas cause symptoms by pressing on the brain or other nervous structures. Therefore symptoms will directly relate to whichever neighbouring structures are compressed. Headache can be a general and sometimes the only symptom. Even small tumours can result in symptoms by producing swelling in the surrounding brain tissue such as a epileptic seizure.
How are meningiomas diagnosed?
Diagnosing a meningioma is usually easy. The best imaging study for this purpose is MRI but CT also produces excellent results.
What is the treatment for meningiomas?
Meningiomas should, when growing in an accessible location, be removed by microsurgical techniques. Most often this can be done radically to provide a cure. Some meningiomas, especially those in the skull base area, are difficult to resect completely without causing damage to other parts of the brain resulting in injury to the patient. In these cases Gamma Knife surgery has been proven to be an excellent adjunctive treatment.
