Herpetic Meningoencephalitis Complicating the Resection of a Vestibular Schwannoma: A Case Report.

After surgery involving cranial nerves and more generally the central nervous system, nonbacterial meningitis should raise suspicion of herpes simplex virus type 1 reactivation. No time should be wasted in diagnosis and treatment; therefore, a polymerase chain reaction testing on cerebrospinal fluid should be systematic in this situation, without neglecting to consider other differential diagnoses.

Endovascular treatment of distal anterior cerebral artery aneurysms: Long-term results.

Background And Purpose: Endovascular therapy is the first-line therapeutic option for intracranial aneurysms, however the results of the endovascular approach for distal anterior cerebral artery (DACA) aneurysms are not well-known. We assessed the immediate and long-term clinical and angiographic outcomes after endovascular coiling of DACA aneurysms.

Materials And Methods: We performed a retrospective analysis of all consecutive DACA aneurysms treated by endovascular coiling.

sEEG is a Safe Procedure for a Comprehensive Anatomic Exploration of the Insula: A Retrospective Study of 108 Procedures Representing 254 Transopercular Insular Electrodes.

Background: The exploration of the insula in pre-surgical evaluation of epilepsy is considered to be associated with a high vascular risk resulting in an incomplete exploration of the insular cortex.

Objective: To report a retrospective observational study of insular exploration using stereoelectroencephalography (sEEG) with transopercular and parasagittal oblique intracerebral electrodes from January 2008 to January 2016. The first purpose of this study was to evaluate the surgical risks of insular cortex sEEG exploration.

Vestibular schwannomas treated with Cyberknife®: clinical outcomes.

Purpose: Fractionated stereotactic radiotherapy (FSR) is a recognized treatment for vestibular schwannomas (VS). This study's aim is to present clinical outcomes and local control (LC) results for patients with VS treated with FSR using the Cyberknife® (CK) in 2 French cancer centers.

Methods: Patients treated with FSR for VS between 2007 and 2012 were retrospectively analyzed.

Expression of minichromosome maintenance MCM6 protein in meningiomas is strongly correlated with histologic grade and clinical outcome.

The 2007 World Health Organization histologic grading of meningiomas is associated with recurrence and clinical outcome. However, distinction of grade I from grade II (atypical) meningiomas can be challenging. In the World Health Organization classification, there are 4 parameters on the basis of which grade II status can be determined: mitotic rate, cytoarchitectural features, brain invasion, and/or histologic subtype.

Treatment of hemorrhagic intracranial dissections.

Objective: To analyze the treatment options in hemorrhagic intracranial dissections.

Methods: This study involved a retrospective review of 27 patients with 29 dissections treated during a 16-year period, mainly by endovascular treatment (EVT).

Results: EVT was performed in the acute stage in 12 of the 29 dissections, and occlusion was performed using coils at the dissection site in six dissections and with proximal balloon occlusion in six dissections.

Aneurysm clipping after endovascular treatment with coils: a report of 13 cases.

In 1996, Civit et al. (Neurosurgery, 38:955-961, 1996) reported a series of eight patients whose aneurysms were clipped after previous embolization with coils. This paper highlighted the safety of this surgery in second line, with a low complication rate and a favorable outcome.

Angioleiomyoma of the cavernous sinus: case report.

Objective: Angioleiomyomas are soft tissue tumors with smooth muscle and vascular components. They are extremely rare in intracranial locations and only three cases have been reported in the literature, including one in the cavernous sinus. Furthermore, long-term follow-up after surgery for a tumor at this site has not been described.

Cavernous angioma within an olfactory groove meningioma. Case report.

The authors present the case of a 60-year-old woman who was admitted to their institution after suffering a subarachnoid hemorrhage (SAH). Neuroimaging data demonstrated an olfactory groove meningioma surrounded by a slight edema, but there was no evidence of SAH, although results of the lumbar puncture demonstrated xanthochromic cerebrospinal fluid. Angiography confirmed the diagnosis of meningioma, but results of magnetic resonance imaging led the authors to suspect a cavernoma within the meningioma.
