The role of repeat resection in the multimodal treatment of gliomas is unclear. Repeat surgery theoretically carries a higher risk of inducing neurological deficits, which might even out any advantage of cytoreduction. We sought to determine whether the occurrence of perioperative infarction is higher for repeat surgery than for first surgery, and sought to(More)
In the treatment of glioblastoma (GBM) the impact of radical tumor resection as first line therapy is beyond controversy. The significance of a second resection in case of tumor-recurrence remains unclear and is an issue of debate. Since GBMs always recur, it is important to determine whether or not patients will benefit from repeat surgery. We performed a(More)
Functional outcome after resection of tumors arising from the gyrus cinguli (GC), part of the limbic system, is not well analyzed. The purpose of this study was to evaluate the feasibility and functional outcome of surgical treatment for a series of 65 patients with gliomas involving the GC. Preoperative data, extent of resection, functional outcome(More)
BACKGROUND Tractography based on diffusion tensor imaging has become a popular tool for delineating white matter tracts for neurosurgical procedures. OBJECTIVE To explore whether navigated transcranial magnetic stimulation (nTMS) might increase the accuracy of fiber tracking. METHODS Tractography was performed according to both anatomic delineation of(More)
BACKGROUND Routine postoperative imaging (PI) following surgery for intracranial meningiomas is common practice in most neurosurgical departments. The purpose of this study was to determine the role of routine PI and its impact on clinical decision making after resection of meningioma. METHODS Patient and tumor characteristics, details of radiographic(More)
BACKGROUND For safe resection of lesions situated in or near eloquent brain regions, determination of their spatial and functional relationship is crucial. Since functional magnetic resonance imaging and intraoperative neurophysiological mapping are not available in all neurosurgical departments, we aimed to evaluate brain surface reformatted imaging (BSRI)(More)
