Meningiomas often are considered benign tumors that can be removed by surgery, but most recurrent meningiomas correspond to histologic benign tumors. The metabolic phenotype of these benign recurrent meningiomas indicated an aggressive metabolism resembling that observed for atypical meningioma. [20]
Depending on the grade of the sarcoma, it is treated with surgery, [8] chemotherapy, and/or radiotherapy.Though surgery is the current standard of care for hemangiopericytomas, metastasis and tumor recurrence occur in more than 30% of patients, in particular recurrence in the pelvis and retroperitoneum [3] and metastasis in bone and lungs.

Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor. Gamma knife radiation and microscopic surgery are common options. Their encapsulated, slow growth makes meningiomas good targets for radiosurgery .
Surgery is often the treatment of choice. Total resection (removal of the tumor) is often possible. However, the best choice of treatment will depend on many individual factors, including: The patient's medical history and overall health condition; The type, location, and size of the tumor; The patient's age
Meningiomas and schwannomas occur in around half of patients with NF2. Meningiomas are tumors that are both intracranial and intraspinal. Schwannomas are tumors that are often centered on the internal auditory canal. Patients with NF2 who have meningiomas have a higher risk of mortality, and the treatment can be very challenging.
Lipomas are usually diagnosed clinically, although imaging (ultrasound, computed tomography, or magnetic resonance imaging) may be utilized to assist with the diagnosis of lipomas in atypical locations. [24] The main treatment for lipomas is surgical excision, after which the tumor is examined with histopathology to confirm the diagnosis. [24]
