First case of cyproterone acetate induced multiple meningiomas in identical female twins: A case report.

Meningiomas are the most common tumors of the central nervous system. Most meningiomas are benign and occur mainly in middle-aged women. Only a few cases of meningiomas in identical twins have been reported.

Prognostic factors for survival in adult patients with recurrent glioblastoma: a decision-tree-based model.

We assessed prognostic factors in relation to OS from progression in recurrent glioblastomas. Retrospective multicentric study enrolling 407 (training set) and 370 (external validation set) adult patients with a recurrent supratentorial glioblastoma treated by surgical resection and standard combined chemoradiotherapy as first-line treatment. Four complementary multivariate prognostic models were evaluated: Cox proportional hazards regression modeling, single-tree recursive partitioning, random survival forest, conditional random forest.

Tau protein as a possible marker of cerebrospinal fluid leakage in cerebrospinal fluid rhinorrhoea: A pilot study.

Introduction: The management of posttraumatic cerebrospinal fluid (CSF) rhinorrhoea remains a clinical challenge. Cerebrospinal fistula is a dural defect responsible for possible CSF leakage into the contiguous air-filled cavities located at the skull base. The risk of central nervous system infection in these conditions is severe and can be life threatening.

Recurrent glioblastomas in the elderly after maximal first-line treatment: does preserved overall condition warrant a maximal second-line treatment?

A growing literature supports maximal safe resection followed by standard combined chemoradiotherapy (i.e. maximal first-line therapy) for selected elderly glioblastoma patients.

Is spinal cord stimulation safe? A review of 13 years of implantations and complications.

Objective: The aim of this review was to evaluate the complications of spinal cord stimulation (SCS) for chronic pain.

Methods: This was a retrospective case series of 212 patients treated with SCS for chronic lower-limb neuropathic pain between March 2002 and February 2015 in a Reims academic hospital. All patients received a surgically implanted paddle-type electrode.

[Adult orbital tumors].

Orbital tumors are a rather frequent pathology. Their diagnosis and treatment may be difficult. They can be benign or malignant.

Transglabellar approach for resection of anterior midline skull base meningiomas: technical note.

Background: We describe our experience of minimally invasive approach of the anterior skull base through the transglabellar approach.

Method: The technical details of the transglabellar approach are described in this article as we have been using it for the past 3 years. After an inter-eyebrow skin incision, the scalp is elevated allowing the creation of a 3-cm bone flap in the frontal sinus, which gives direct access to the anterior midline skull base.

Metastatic odontoid fracture management by anterior screw fixation and kyphoplasty.

We report the case of a patient diagnosed with a pathological fracture of the odontoid dens related to a renal carcinoma metastasis and treated by an original technique. In order to achieve correct stabilization of the fracture and to preserve rotational neck mobility, an anterior approach combining an odontoid screw fixation and a balloon kyphoplasty was performed. This minimal invasive strategy provided satisfactory clinical and radiological results for this unstable lesion.

[Brain abscess due to Nocardia cyriacigeorgica simulating an ischemic stroke].

Nocardia spp. are bacteria often implicated in pulmonary diseases and central nervous system infections, especially in immunocompromised patients. We report here the case of an immunocompromised woman presenting an insidious brain abcess initially treated as a cerebral stroke.

Combined treatment of brain AVMs with use of Onyx embolization followed by radiosurgery.

Background And Purpose: The treatment of cerebral AVMs is complex, reliant on interventions such as embolization, surgery, and radiosurgery, or a combination of these modalities. To date, treatment with the embolic agent Onyx, followed by radiosurgery, has not been evaluated. The goal of this study was to evaluate the safety and efficacy of this combination in a homogeneous, monocentric series.

Fractionated stereotactic radiotherapy for acoustic neuromas: a prospective monocenter study of about 158 cases.

Purpose: To evaluate long-term outcomes and efficacy of fractionated stereotactic radiotherapy in the treatment of acoustic neuromas.

Material And Methods: Between January 1996 and December 2009, 158 acoustic neuromas were treated by FSR in 155 patients. They received a dose of 50.

[Treatment for intracranial aneurysms].

Aneurysm rupture is suspected in case of sudden, intense headache, sometimes associated with nausea or vomiting, focal neurologic deficit or loss of consciousness. Aneurysm rupture is a diagnostic and therapeutic emergency that has to be managed in highly specialized centers. Ruptured aneurysms have to be treated in emergency to avoid rebleeding.

Intramedullary spinal cord cavernous angioma in children: case report and literature review.

Introduction: Intramedullary cavernous angiomas (ImCA) of the spinal cord are very uncommon malformations especially in the pediatric population where only ten cases have yet been reported within the available literature.

Case Report: In this paper, the authors report the case of a 12-year-old girl presenting with a T11 level hematomyelia because of a cavernous angioma. Microsurgical excision was performed with good clinical outcome and no magnetic resonance imaging evidence of residual cavernoma 30 months later.

Acquired aqueductal stenosis in preterm infants: an indication for neuroendoscopic third ventriculostomy.

Object: The object of this study is to demonstrate the delayed occurrence of aqueductal stenosis in preterm infants who have suffered from intraventricular hemorrhage (IVH) and to try to explain the mechanisms of this stenosis.

Method: From January 1996 to June 2002, 1,046 premature infants were admitted to our institution. Thirty-six neonates suffered from grade 3 or 4 intraventricular hemorrhage (Papile grading), of whom 16 died.
