Gamma Knife Radiosurgery for Posterior Cranial Fossa Meningioma

Treatment of meningioma in the posterior cranial fossa represents a formidable challenge for the neurosurgeon. Although surgical resection is the primary treatment option for posterior fossa meningiomas, there is an important risk of injury to neurovascular structures adjacent to the brainstem. Furthermore, residual or recurrent tumours following resection are not rare, in spite of recent advances in microsurgery and anaesthesiology, including intraoperative neurophysiological monitoring.
