Acute Hemorrhage Following Gamma Knife Radiosurgery to a Clival Meningioma

Gamma Knife radiosurgery (GKS) is an effective therapy for small (<3 cm) meningiomas of the skull base in medically-complex patients for whom open surgery carries an unacceptable risk of morbidity and mortality. While infrequent, hemorrhagic events after GKS do occur. To date, nine cases of intratumoral hemorrhage after GKS for meningiomas have been reported in the literature, with eight occurring in a delayed fashion.
