摘要: Meningiomas are extra-axial CNS tumors which have a female predominance and occur in middle-to-late adult life. Most meningiomas (90%) benign, 6% atypical small proportion (2%) malignant. patients diagnosed with meningioma undergo surgical resection to relieve neurological symptoms. Complete is often curative. For most incompletely resected or recurrent not previously irradiated, radiotherapy administered. Radiotherapy may be administered as either conventional external beam irradiation stereotactically by linear accelerator, gamma knife cyberknife radiosurgery. Advocates of stereotactic suggested this therapy lieu surgery particularly poor risk patients, eloquent surgically inaccessible locations advanced age. When the unresectable all other treatments (e.g., radiotherapy) failed, hormonal chemotherapy considered. Notwithstanding limited data, hydroxyurea has been modestly successful meningiomas.
