Context: Treatment of Primary CNS Tumors by Tumor Type
WHO grade I meningiomas are usually curable when they are resectable. With the increasing use of sensitive neuroimaging tools, there has been more detection of asymptomatic low-grade meningiomas. Most appear to show minimal growth and can often be safely observed while therapy is deferred until growth or the development of symptoms.[33,34]
Treatment options for meningeal tumors include:
Active surveillance with deferred treatment, especially for incidentally discovered asymptomatic tumors.[33,34]
Surgery.
Stereotactic radiosurgery for tumors smaller than 3 cm.
Surgery plus radiation therapy in selected cases, such as for patients with known or suspected residual disease or with recurrence after previous surgery.
Fractionated radiation therapy for patients with unresectable tumors.[35]

The prognoses for patients with WHO grade II meningiomas (atypical, clear cell, and chordoid), WHO grade III meningiomas (anaplastic/malignant, rhabdoid, and papillary), and hemangiopericytomas are worse than the prognoses for patients with low-grade meningiomas because complete resections are less commonly feasible, and the proliferative capacity is greater.
Treatment options for grades II and III meningiomas and hemangiopericytomas include:
Surgery plus radiation therapy.
