This paper reports on stereotactic biopsy combined with stereotactic 125iodine brachytherapy (SBT) for locally recurrent, previously irradiated cerebral metastases, focusing on feasibility, complications, cerebral disease control, and survival. All patients with suspected locally recurrent metastases detected by MRI were selected for this combined(More)
To find out whether the use of stereotactic techniques for fractionated radiotherapy reduces toxicity to the endocrine and visual system in patients with benign perioptic tumors. From 1993 to 2009,  29 patients were treated with fractionated stereotactic radiotherapy. The most frequent tumor types were grade I meningioma (n  = 11) and pituitary adenoma (n (More)
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. Between August 1990 and December 2003, 16 patients with 28 meningiomas WHO II and III were(More)
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 long-term(More)
The efficacy and safety of stereotactic radiosurgery (SRS) for treatment of intracranial meningiomas has been demonstrated in numerous studies with short- and intermediate-term follow-up. In this retrospective single-center study, we present long-term outcomes of SRS performed with a linear accelerator (LINAC) for typical intracranial meningiomas. Between(More)
We evaluated the efficacy of interstitial brachytherapy (IBT) using 125Iodine (125I) seeds for treatment of papillary tumors of the pineal region. Between September 2003 and September 2010, four patients (M/F = 2/2; median age, 57.3 years; range 29.2–69.1 years) with papillary tumors of the pineal region underwent IBT using 125I seeds. Before brachytherapy(More)
We present the long-term results of a consecutive series of patients with meningiomas treated by LINAC-radiosurgery using the micro-multi-leaf collimator technique (μMLC). Between May 2001 and July 2009, 78 patients (m:f = 24:54; median age, 56.8 years; range, 20.1–81 years) with 87 intracranial meningiomas (78 WHO I, seven WHO II, two WHO III) were treated(More)
OBJECTIVE To create probabilistic stimulation maps (PSMs) of deep brain stimulation (DBS) effects on tremor suppression and stimulation-induced side-effects in patients with essential tremor (ET). METHOD Monopolar reviews from 16 ET-patients which consisted of over 600 stimulation settings were used to create PSMs. A spherical model of the volume of(More)
PURPOSE Orientating the angle of directional leads for deep brain stimulation (DBS) in an axial plane introduces a new degree of freedom that is indicated by embedded anisotropic directional markers. Our aim was to develop algorithms to determine lead orientation angles from computed tomography (CT) and stereotactic x-ray imaging using standard clinical(More)
