Stereotactic gamma knife radiosurgery in the treatment of brain metastases

Gamma knife stereotactic radiosurgery for radiation-induced meningiomas.

BACKGROUND Radiation-induced meningiomas present a unique clinical dilemma given the fact that patients with these tumors have often received a prior full course of radiotherapy. As such, traditional radiotherapy is limited by lifetime tissue tolerances to radiation, leaving surgery and radiosurgery as attractive treatment options. OBJECTIVES To ascertain the safety and efficacy of Gamma Knif...

Gamma Knife Stereotactic Radiosurgery for Nonvestibular Cranial Nerve Schwannomas.

BACKGROUND Nonvestibular cranial schwannomas represent a rare type of benign intracranial tumor. Few studies have evaluated the use of stereotactic radiosurgery (SRS) as a primary management option for these lesions. We performed a retrospective review of our institution's experience focusing on efficacy with regard to tumor control and clinical symptom stabilization as well as treatment safety...

Outcomes of Gamma Knife Radiosurgery in Patients With Parasagittal Meningioma

Background & Aim: The treatment of Parasagittal Meningioma (PSM) is always a challenge, especially when the tumor has already invaded the critical structures like venous sinuses. This study aims at evaluating the outcomes of Gamma Knife Radiosurgery (GKRS) in patients with PSM. Methods and Materials/Patients: In this descriptive retrospective study, we reviewed the medical records of 61 patien...

Optimization of gamma knife radiosurgery

The Gamma Knife is a highly specialized treatment unit that provides an advanced stereotactic approach to the treatment of tumors, vascular malformations, and pain disorders within the head. Inside a shielded treatment unit, beams from 201 radioactive sources are focused so that they intersect at the same location in space, resulting in a spherical region of high dose referred to as a shot of r...
