Malignant transformation of a vestibular schwannoma after gamma knife radiosurgery.
Stereotactic radiosurgery is used to treat benign tumours, but its long-term effects are not fully understood. Here we describe a vestibular schwannoma that underwent malignant transformation 6 years after gamma knife radiosurgery applied to the tumour remnant after a primary resection. Histological specimens of the original specimen did not show any atypical features. Genotyping showed a TP53 ...
متن کاملOutcomes 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...
متن کاملImage-guided Radiosurgery Using the Gamma Knife
Image guided brain surgery became a reality in the mid-1970s after the introduction of the fi rst methods to obtain axial imaging using computed tomography (CT) [9]. The recognition of cranial disease much earlier in its clinical course prompted the need for concomitant minimally invasive technologies to both diagnose and to treat the newly recognized brain tumors and vascular malformations. Su...
متن کاملA meta-analysis of treatment of vestibular schwannoma using Gamma Knife radiosurgery
AIM OF THE STUDY One of the alternative methods of surgical treatment of vestibular schwannoma is Gamma Knife radiosurgery. The purpose of this metaanalysis was to analyze the progress in treatment of vestibular schwannoma using Gamma Knife radiosurgery based on data in the literature of the last five years. MATERIAL AND METHODS In the collected English-language literature from the years 2007...
متن کاملGammaPlan-Leksell Gamma Knife radiosurgery treatment planning verification method.
This work provides a method for an independent check of Gamma Knife GammaPlan radiosurgery calculations, named the spherical approximation method or SAM. Based on skull dimension measurements, the treated volume of the head is modeled as a sphere of radius R. With this approximation, an analytical solution for fast ray tracing of the path length, for each of the 201 beamlets, of the Gamma Knife...
