BACKGROUND The optimal management of subtotally resected or recurrent malignant meningiomas remains controversial. We evaluated the efficacy of linear accelerator (LINAC) radiosurgery for atypical and anaplastic meningiomas after incomplete resection or treatment of recurrences. METHODS Between August 1990 and December 2003, 16 patients with 28(More)
BACKGROUND AND PURPOSE Stereotactic linear accelerator-based radiosurgery (LINAC-RS) is increasingly used for microsurgically inaccessible or recurrent pituitary adenomas. This single-center study evaluates the long-term follow-up after LINAC-RS of nonsecreting pituitary adenomas (NSA). PATIENTS AND METHODS Between 1992 and August 2008, 65 patients with(More)
BACKGROUND The spinothalamocortical tract (STC) is seen as a neural tract responsible for or involved in the generation or transmission of thalamic pain. Either the thalamus itself or the posterior limb of the internal capsule (PLIC) are targets for deep brain stimulation (DBS) in patients with thalamic pain, but due to its low contrast, conventional MRI(More)
OBJECTIVE In some patients, chronic subdural haematoma (cSDH) appears to occur spontaneously with frequent re-bleeding events. The pathophysiology of this phenomenon is still poorly understood. Because coagulation factor XIII (FXIII) is known to be involved in vascular integrity, endothelial barrier function and wound healing, we evaluated the role of FXIII(More)
BACKGROUND Pallidal deep brain stimulation (GPi-DBS) effectively ameliorates idiopathic dystonia, although approximately 15% of patients respond insufficiently. Although various thalamic and subthalamic targets have been suggested for dystonic tremor, no systematic studies have been published on thalamic DBS in dystonic tremor. We assessed the effect of(More)
Cell-therapy was proposed to be a promising tool in case of death or impairment of specific cell types. Correct identification of implanted cells became crucial when evaluating the success of transplantation therapy. Various methods of cell labeling have been employed in previously published studies. The use of intrinsic signaling of green fluorescent(More)
BACKGROUND The management of deep-seated cerebral cavernous malformations (CCMs) is still controversial. Although surgery remains the treatment of choice in patients with recurrent hemorrhage, patients with CCMs located in the brainstem are in many cases not eligible for resection due to high procedure-related morbidity and mortality. We evaluated the(More)
PURPOSE To evaluate the efficacy of interstitial radiosurgery (IRS) for pineal parenchymal tumors (PPTs). PATIENTS AND METHODS 18 consecutively admitted patients (twelve male and six female, age range 6-68 years, median age 34 years) with PPTs (eight pineocytomas, ten malignant PPTs) were treated at the authors' institution with IRS using stereotactically(More)
BACKGROUND Rosai-Dorfman disease is an idiopathic, histoproliferative disorder characterized by massive painless lymphadenopathy. The favorable treatment of Rosai-Dorfman disease affecting the central nervous system is surgical resection. Histological and immunohistochemical confirmation is essential for a definitive diagnosis. CASE REPORT The authors(More)
AIMS To evaluate the efficacy of interstitial brachytherapy using (125)iodine ((125)I) seeds for the treatment of recurrent multimodal treated medulloblastoma. MATERIALS AND METHODS Between September 1989 and August 2009, 12 patients (female:male=3:9, median age 19 years, range 7-55 years) with 23 recurrent medulloblastomas underwent interstitial(More)
