Extracranial Facial Nerve Schwannoma Treated by Hypo-fractionated CyberKnife Radiosurgery
Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged...
متن کامل[High-grade glioma after stereotactic radiosurgery for vestibular schwannoma].
Stereotactic radiosurgery undoubtedly represents an important therapeutic procedure for various intracranial pathologies, especially tumours, although they are not entirely complication-free. Radiosurgery have been considered a good management strategy for the majority of small-to-medium size vestibular schwannomas. The authors describe a case of high-grade glioma associated with a previous rad...
متن کاملFrameless Fractionated Stereotactic Radiosurgery for Vestibular Schwannomas: A Single-Institution Experience
OBJECTIVE To examine tumor control, hearing preservation, and complication rates after frameless fractionated stereotactic radiosurgery (SRS) in patients with vestibular schwannomas (VS). METHODS Thirty-seven patients treated with fractionated SRS from 2002 to 2011 were retrospectively analyzed. Ninety-five percent were treated with 25 Gy in five fractions, targeting a median tumor volume of ...
متن کاملLinear accelerator radiosurgery for vestibular schwannoma.
OBJECT The use of radiosurgery in the treatment of acoustic neuromas has increased substantially during the last decade. Most published experience relates to the use of the gamma knife. In this report, the authors review the methods and results of linear accelerator (LINAC) radiosurgery in 44 patients with acoustic neuromas who were treated between 1993 and 1997. METHODS Computerized tomograp...
متن کاملImportance of CBCT setup verification for optical‐guided frameless radiosurgery
The purpose of this study is to quantify the discrepancy between optical guidance platform (OGP) frameless localization system (Varian) and Trilogy on-board imaging (OBI) system (Varian) for setting up phantom and stereotactic radiosurgery (SRS) patient; and to determine whether cone-beam CT (CBCT) is necessary for OGP patient setup, and compare CBCT and orthogonal kV-kV in term of their verifi...
