Aggressive surgical removal of the intracranial hemangiopericytoma with wide margins when possible. Complete resection is challenging due to vascular nature and location.
Stereotactic Radiosurgery
Focused radiation delivery to tumor margins using precise targeting technology. Often used adjuvantly after surgery or for unresectable or recurrent lesions.
Additional treatment options
Fractionated Radiation Therapy
Conventional external beam radiation delivered in multiple fractions for tumors in sensitive locations or when radiosurgery is not appropriate.
procedureSystemic Therapy
Targeted agents or chemotherapy used for metastatic or recurrent disease that cannot be controlled with local therapies alone.
medicationLong-term Imaging Follow-up
