Further clinical trials are necessary to confirm a possible therapeutic effect and evaluate the toxicity of statins.

With the steadily increasing use of internet resources, this approach can be expected to expand. Physicians should be prepared to deal appropriately with this subgroup of patients and their relatives to ensure that self-help activities support but do not endanger optimal care.

The authors describe the first case of a perforating frontobasal injury caused by a wild deer's antler. Associated lesions involved the endonasal area and the left orbit. A multidisciplinary approach was used to address all lesions in a one-stage operation resulting in a full recovery of the patient. Apart from the problem of a possible contamination of the head wound, injuries caused by wild animal attacks should be treated the same way as comparable "regular" cases. Adequate coverage of dural and bone def...

The expression and distribution of these artefacts depends on both the clip-gantry angle and the plane of image reconstruction. Overall, there is no correlation between clip-gantry angle and either the severity or the spatial distribution of clip artefacts leading to observable restrictions in the evaluation of surrounding structures.

Adjacent level decompensation was neither influenced by the length of the fusion nor the performed procedure. Compared to anterior instrumentation, posterior instrumentation showed a tendency for a lower revision rate without statistical significance. However, the posterior procedures showed a high revision rate regarding to wound healing problems.

None of the software applications was able to display the CST in its full anatomical extent. Especially the lateral precentral areas were not pictured. Surprisingly, the application of the four distinct FT-tools did not lead to comparable tracking results. As very similar or identical tracking algorithms were used, this difference cannot be easily explained. Clearly, neurosurgeons have to be cautious about applying fiber tracking results intraoperatively, especially when dealing with an abnormal or distorted fiber tract anatomy. The authors recommend the use of adjunct strategies such as intraoperative electrophysiology t...

This potential may be greater in multifocal GBM. FNA is a valuable method for the definite diagnosis of metastatic GBMs. Although several theories have been postulated, the route of remote cutaneous dissemination and the mechanism of multifocal recurrence remain to be elucidated.

Certain subtypes such as transsphenoidal variants may be as rare as 1 in 700 000 live births. These rare encephaloceles are classified into five anatomic types: spheno-ethmodial, transsphenoidal, spheno-orbital, transethmoidal, and spheno-maxillary. Here we present an exceedingly rare variant of a non-midline basal encephalocele of the spheno-orbital type, which was treated by resection of the encephalocele, which contained dysplastic central nervous system tissue, on day four post partum.

Tumor growth was slow in all cases; no clinical symptoms have been registered thus far. The intervals between control investigations may even be prolonged depending on the location of the tumor. In this age group the operation appears to pose a greater risk than the presence of an asymptomatic tumor.

Staging examinations including CT scan of the thorax and abdomen as well as bone scintigraphy were inconspicuous. The patient underwent 6 cycles of neoadjuvant chemotherapy (VIDE, similar to Euro Ewing 99). Presurgically, embolisation of the L4 and L5 vertebral bodies was performed on both sides. The tumour was removed via a dorsal approach with corporectomy of L5 and resection of the right nerve root of L5. The defect was bridged by a titanium cage filled with bone cement; a dorsal L4-S1 instrumentation was performed. Early postopera...

Furthermore, the position was not precisely concentric around the electrode. Nevertheless, the mean deviation after measuring the contact position in both CT and MR was less than 1 mm in all three planes. Both techniques are eligible for postoperative localisation of DBS electrodes, with a small imprecision of the non-stereotactic MR compared to the stereotactic CT. This might be compensated by the fact that postoperative MR can rule out asymptomatic postoperative complications e.g. haemorrhages or infarctions, without radiation exposure of the patient.

The different localizations may require different surgical approaches, with different chances of complete removal. The location and extent of the intraorbital tumor results in different recurrence rates, lower for superolateral and inferomedial forms than for orbital apex and diffuse forms.

The bilateral compression of the trigeminal nerve-pons junction in our patient suggests that the external pressure probably adds to the internal defects in central myelin formation, structure or maintenance. Nevertheless, the mid-term follow-up after MVD clearly shows that the causal treatment for TN can be successfully applied to patients with TN plus CMT.

Magnetic resonance imaging of the lumbar spine showed a dumbbell lesion at the L5-S1 neural foramen, with enlargement of the foramen and extension into the left paraspinal compartment. Although MR imaging studies were strongly suggestive of a dumbbell radicular schwannoma, the histological diagnosis was an osteoblastoma of the lumbar spine originating from the left L5 pedicle with intracanalicular, intraforaminal and extracanalicular extension.

The genetic analysis of DNA from the meningioma revealed no oncogenic mutation in the RB1 gene. The analysis of meningioma cells by flow cytometry revealed the following immunophenotype: vimentin++ CD56+ GFAP- EGFR-. Intermediate intensities of Her-2/neu and Pgp expression were detected in a small percentage of tumour cells. Data suggest that the tumour was most likely induced by radiotherapy and did not arise as a second tumour as there was no hereditary predisposition to retinoblastoma.

However, various complications related to PMMA vertebroplasty have recently been reported. We experienced three cases with progressive collapse of PMMA-augmented vertebra. Collapse progressed after augmentation in cases where PMMA conglomerated without contiguous bone interdigitation. A high viscosity of the PMMA preparation and vertebral body cavitory lesion may play a role in progressive vertebral collapse. To avoid this complication, bone cement should be injected sufficiently and permeate to contiguous bone to create strong support and anchorage. PMID: 18393165 [PubMed - in proces...

Due to this anatomical situation a hypertrophic ligamentum flavum may contribute significantly to nerve root compression at the level of the lateral spinal recess. This has to be kept in mind during surgical decompression, which might be incomplete unless these hypertrophied parts are completely removed.

In contrast, dural types of vascularisation, a visible tumour-brain interface, meningioma growing in a non-eloquent area, and the absence of peritumoral oedema are favourable predictive parameters. To go by the results, in the presence of the last two parameters the patient need not be exposed to the risks of invasive selective angiography.

MRI was suspicious for arteriovenous malformation and the dorsal horn of the right lateral ventricle was enlarged. Digital subtraction angiography showed complex venous malformations with abnormal supratentorial venous drainage and bilateral cerebellar DVAs with associated varix nodes. This is a unique case of complex supra- and infratentorial abnormal venous drainage. After considering the complexity of these venous anomalies and the fact that the patient was asymptomatic there was no reasonable indication for treatment.

It consists of debridement and fusion for spondylodiscitis together with epidural abscess drainage using a microscopically assisted percutaneous technique. In the period from April 2000 to April 2004, 5 patients with spondylodiscitis and an accompanying extended epidural abscess were operated on. The mean age of the patients was 66 years. There were 4 males and one female. The follow-up period ranged from 3-12 months. To manage the extended epidural abscess, the authors created one or two drainage sites along the extension of epidural abscess.

During mild fluid restriction for the treatment of the hyponatremia, acute renal failure occurred. The renal failure was resolved by treatment with furosemide. Fluid restriction is considered a standard therapeutic approach for the treatment of this probably SIADH-induced hyponatremia. Until now, acute renal failure has not been reported under these circumstances. This unique case demonstrates the need of close monitoring of patients with delayed hyponatremia following pituitary surgery.

If the tumor is large and the sinus is patent, we recommend gross total resection with no removal of SSS. If postoperative or follow-up MR imaging demonstrates residual tumor or recurrence, gamma-knife surgery should be performed. If a large meningioma has completely obliterated the SSS, our policy is to remove the tumor and all sinus tissue without reconstructing the SSS.

An inflammatory process of the dural membrane with migration of Langerhans' cells could be the physiopathological basis for the formation of intradural eosinophilic granuloma. This is a mechanism similar to that of chronic subdural haematoma formation. Histological demonstration of eosinophilic granuloma cells around the lesion margin suggests the need to remove dura mater peripherally to the lesion.

Computed tomography (CT) as well as magnetic resonance imaging (MRI) revealed an intracranial, space-occupying mass with no meningeal attachment, located in the left frontal lobe. The entire tumour was removed, the pathological examination revealed a chondroma. The origin of this tumour is analysed, the clinical and histological findings are described and the literature is reviewed.

It combines the advantages of a blunt muscle-spreading approach that produces little damage to the soft tissues, and the avoidance of large bone removal that may jeopardize vertebral stability. Since this approach does not permit sufficient exploration of the intervertebral disc space of origin, it should be limited to patients without significant bulging of the disc itself.

However, hemangioblastomas should not be ignored as a possible differential diagnosis for intraparenchymal brainstem hemorrhage. While the prognosis in hypertensive brainstem bleedings is mostly disastrous and surgery rarely indicated, an operative therapy should be considered in cases of hemorrhages caused by underlying tumors. Especially in the treatment of hemangioblastoma, the surgical management strategy is crucial for a successful result. Therefore, the authors recommend including the search for hemangioblastomas into the diagnostic workup in patients with brainstem hemorrhages.

The functionality of this system has been proven by technical tests. Recording and integration of the ultrasound data can be repeated at any time during surgery and can be used to update anatomical data and consequently for resection control. Another application is the intraoperative adaptation of preoperative datasets (MRI or CT) in order to compensate for "brain shift" during neurosurgical operations.

Most pedicle screws are still inserted conventionally. Although nearly 50 % of German neurosurgeons believe that spinal navigation could enhance safety when placing pedicle screws, they clearly reject efforts to make spinal navigation mandatory. With only one exception, the German neurosurgical community unanimously rejects the idea that placing pedicle screws without spinal navigation is medical malpractice.

WHO grade II astrocytomas, oligodendrogliomas, and mixed gliomas are characterized by their infiltrative growth, frequent tumor recurrence and a more than 50 % risk for malignant progression. In contrast, pilocytic astrocytomas and SEGAs are circumscribed tumors amenable to a (radio)surgical cure. There are few universally accepted guidelines for the treatment of low-grade gliomas.

He commenced his work in the field of neurosurgery in Münster from 1937. In 1938 he published a new classification of the anterior circulation of cerebral arteries in states of tumorous mass lesions. From 1939 through to the end of WW II, Tönnis and Fischer-Brügge worked closely together, mainly in the field of war surgery. After WW II, in 1949, Fischer-Brügge published another relevant clinical contribution on the "Clivuskantensyndom".

The surgical approach was determined by the location and type of the lesion. The most common primary cancers that metastasized to the orbit were lung cancer, and breast cancer. In 6 patients, there was no history of cancer and in 1 patient the primary site remained obscure despite systemic evaluation. Three patients showed recurrent tumor growth despite chemo- and/or radiotherapy. The mean survival time was 15 months after diagnosis of orbital metastases. The systemic prognosis is generally poor. A multidisciplinary treatment is required. Therapeutic options include surgical biopsy, debulking or excision, hormonal therapy, chemotherapy, and radiation therapy. ...

A second objective was to assess segmental bony fusion using this technique. 21 patients, suffering from degenerative disc disease of the cervical spine, were included into this prospective study. They all underwent anterior decompression, cage insertion and plate stabilisation. The cage (Rabea, Signus Medizintechnik, Alzenau, Germany), was filled with bone chips made from the anterior osteophytes of the segment that underwent discectomy.

It lies along a natural corridor and is non-muscle splitting. Although it requires a deep surgical corridor, the transaxillary approach allows definitive treatment of both bony and soft-tissue components causing TOS, provided the anatomical boundaries are recognized and respected. A persistent cervical rib, however, calls for an additional ventral approach. The complications are minimal and the results are predominantly acceptable.

Its thinnest middle part immediately above the optic recess is composed mainly of gliotic tissue. Above, prominent loosened tissue and the rather rudimental structure of the OVLT seem to be additional favorable factors for a safe fenestration of the LT.

An AVM surrounding the trigeminal nerve was demonstrated on thin-slice heavily T (2)-weighted 3D-sequence on magnetic resonance imaging (MRI) and confirmed by angiography. The first therapeutic step was endovascular embolization with complete obliteration of the AVM and cessation of pain. Nevertheless surgical excision was performed in order to remove compressive vessels and to prevent a recurrence of pain.

The latencies after rTCMS are close to those of normal data after single TCMS, which indicates that in awake humans identical cortical and spinal structures are similarly activated. The discrete variations of latency and amplitude after changing the frequency and stimulus number suggest that inhibitory and excitatory mechanisms on the cortical and/or spinal level modulate the muscle response.

The absence of brain damage may due to two factors: 1) in elderly patients with hyperostosis, an additional atrophy of the brain is present; 2) extracerebral tumors, with their space-occupying growth, shift the underlying brain away from the calvaria. Considering the design of a robot-assisted trepanation system, the following conclusions seem possible: dural tears cannot be avoided because predisposing factors are overriding. For improved safety, additional, specialized instrumentation is required.

It is not enough to anticipate good from such use: morality is concerned not merely with outcome, but with choices and their impact on character. The human moral subject is the human organism, who has rights and interests from the beginning of his or her existence. Harvesting cells or tissue from an embryo or fetus who is deliberately destroyed -- in some cases, by the harvesting itself -- is a violation of the rights of the individual concerned. To accept cells or tissue from those who did the harvesting (as opposed to using a much older cell-line) is to give the impression that we condone the harvesting, and indeed the taking of the donor...

Recent studies have demonstrated that ceftriaxone induces reversible precipitates in the gallbladder. This complication is referred to as "biliary pseudolithiasis", and it has symptoms similar to the raised intracranial pressure (ICP) symptoms of the perioperative period. Symptomatic biliary pseudolithiasis should be kept in mind in all pediatric neurosurgery cases under ceftriaxone therapy in order to prevent unnecessary postoperative investigations and surgery.

In meningiomas after subtotal surgical resection, the age of the patients seems to present a predictive factor for tumor growth in analogy to our previous observation in incidental meningiomas. Significantly higher relative growth rates were detected in younger patients. Gender does not seem to play a major role as a predictive factor. Radiological features such as calcification or T (2)-signal intensity may provide additional information to predict the growth potential of meningiomas. Close clinical and radiological observation should be performed in young patients harboring tumors with absence of calcification or high T (2)-signal ...

We compared six different co-registration algorithms including surface-oriented, mutual information-based and landmark-based methods. The resulting overlay matrices were analyzed by calculating rotational and translational shifts and by judging co-registered MRI and CT scans visually. A brain surface oriented method had the lowest rotational (axial 0.7 +/- 0.6 degrees; coronal 1.7 +/- 1.1 degrees; sagittal 1.9 +/- 1.8 degrees) and translational shifts (3.7 +/- 1.3 mm). It was judged visually to be the best, had a low intra- and inter-observer variability, and lasted approximately 15 minutes.
