title: [Meningiomas].
abstract: Meningiomas account for approximately one-fourth of all primary central nervous system tumour, arising from arachnoidal cells surrounding brain and spinal cord. They usually affect older adults, particularly women. Ninety percent of meningiomas are slow growing benign tumours. Meningiomas are revealed by various symptoms including neurologic deficits and epileptic seizures. Surgery remains the treatment of choice. Fractionated radiotherapy or stereotactic radiosurgery are used for meningiomas that are recurrent, surgically inacessible, partially excised and either atypical or malignant. Most meningiomas have good long-term prognosis after treatment, some dysplay aggressive clinical behaviour leading to increased patient morbidity and mortality.
