Endoscopic Visualization of an Iatrogenic Valve Mechanism – Elucidating the Pathogenesis of Postoperative Tumor Bed Cysts  Voir?

Space-occupying tumor bed cysts have been reported after resection of intracranial tumors, although the exact mechanism of their pathogenesis is unclear. Opening of the ventricular system during the tumor resection appears to be a risk factor. Occlusion of the surgical opening of the ventricle using fibrinogen-coated collagen fleece has been suggested to restore the integrity of the ventricular system. Here we present a clinical image depicting an iatrogenic valve mechanism caused by a fleece intended to seal a surgical opening of the lateral ventricle, leading to development of a space-occupying tumor bed cyst and cerebrospinal fluid fistula.

In Vivo Microscopy in Neurosurgical Oncology  Voir?

Intraoperative neurosurgical histopathologic diagnoses rely on evaluation of rapid tissue preparations such as frozen sections and smears with conventional light microscopy. Though useful, these techniques are time consuming and therefore unable to provide real-time intraoperative feedback. In vivo molecular imaging techniques are emerging as novel methods for generating real-time diagnostic histopathologic images of tumors and their surrounding tissues. These imaging techniques rely on contrast generated by exogenous fluorescent dyes, autofluorescence of endogenous molecules, fluorescence decay of excited molecules, or light scattering.

Arterial Spin Labeling Method as a Supplemental Predictor to Distinguish Between High- and Low-Grade Gliomas  Voir?

Preoperative evaluation of malignancy in gliomas is important for surgical planning, particularly to determine whether a 1,3-bis-2-chloroethyl-1-nitrosourea wafer should be placed into the tumor cavity. In some cases, the intraoperative pathologic diagnosis of World Health Organization grade differs from the final diagnosis. Supplemental methods in addition to the routine contrast tomography or magnetic resonance imaging sequences may provide a more accurate preoperative diagnosis. Because tumor vascularity has been useful in distinguishing between low- and high-grade gliomas, we evaluated the accuracy of the arterial spin labeling (ASL) method, which could measure the cerebral blood flow (CBF) without using contrast medium, to determine the malignancy of gliomas.

Divergent Bilateral Posterior Lumbar Interbody Fusion with Cortical Screw Fixation: Description of New Trajectory for Interbody Technique from Midline Exposure  Voir?

A major drawback to use of cortical bone trajectory pedicle screws (CBTPSs) with traditional posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion grafts is that traditional graft insertion trajectories require wider posterior exposure. This wider exposure, beyond the limits otherwise required for CBTPS placement, negates a primary benefit of CBTPS fixation. The aim of this study was to define an alternative surgical technique for interbody graft placement that, when used in conjunction with CBTPS fixation, permits both minimal soft tissue dissection and optimal graft placement.

It is even more uncommon for this abnormal communication to be caused by an ectopic prolactinoma arising from the sphenoid sinus and eroding into the sella. This atypical growth pattern makes diagnosis very difficult because there may be no displacement of the normal pituitary gland. The first reported case of a patient with an ectopic prolactinoma originating within the sphenoid sinus presenting primarily with meningitis is presented, and the management strategy and surgical and nonsurgical treatment options are discussed.

Oncogenic Viruses in Skull Base Chordomas  Voir?

Chordomas are rare tumors assumed to derive from notochordal remnants. We believe that a molecular switch is responsible for their malignant behavior. The involvement of oncogenic viruses has not been studied, however. Thus, in the present study, we investigated the presence of oncogenic viruses in chordomas.

Supernumerary Abducens Nerves: A Comprehensive Review  Voir?

Branching and/or replication of the abducens nerve is not an uncommon occurrence. Although numerous variations have been documented, the rarest forms are duplicated or triplicated nerves, where multiple nerve roots originate from the brainstem, travel intracranially, and attach to the lateral rectus as separate entities.

Global Neurosurgery  Voir?

In this issue of WORLD NEUROSURGERY, Franco Servadei (President of the World Federation of Neurosurgical Societies), et al address our ongoing global neurosurgery crisis (Role of Neurosurgery in Countries with Limited Facilities: Facts and Challenges on pages 315-321). This wonderful review of the current status of global neurosurgery, with the authors' accompanying critique and recommendations for future action, have stimulated further invited commentary, the first two of which are by James Bean and Robert Dempsey (also presented in this issue on pages 322-324 and pages 325-327).

Less Dogmatic Approach to Severe Traumatic Brain Injury  Voir?

We appreciate the comments made by Szczygielski et al1 to our paper entitled “Cisternostomy for Refractory Posttraumatic Intracranial Hypertension.” Szczygielski et al,2 in a mouse model of traumatic brain injury (TBI), showed that decompressive craniectomy (DC) was associated with increased development of brain edema and hemorrhagic transformation of the contusion zone that results in impaired neurologic outcome. Though the findings of similar studies in literature are not unanimous,3 the authors attributed the variance of results to the heterogeneity of the brain injury that is often found in severe TBI.

Letter to the Editor Regarding “Cisternostomy for Refractory Posttraumatic Intracranial Hypertension”  Voir?

We read with great interest the case report of Giammattei et al,1 providing a succinct yet significant description of surgical cisternostomy application used for the treatment of increased intracranial pressure (ICP) after brain trauma. The authors refer to our animal study as a rationale for their treatment strategy because we were able to report increased neurologic impairment and extended structural damage following decompressive craniectomy in a mouse model of closed head injury.2 We are glad to see that our preclinical investigation has been recognized by clinical researchers and are eager to provide some reflections considering surgical decompression after traumatic brain injury (TBI) from the vantage point of an experimental neurotraumatologist.

In Reply to the Letter to the Editor “On the Use of Catheter Angiography for Stereoelectroencephalography Trajectory Planning”  Voir?

We received the commentary from Dr. Cardinale regarding our protocol for stereoelectroencephalography (SEEG) electrode implantation with great enthusiasm. We believe that this strategy enables the safe planning of multiple, complex electrode trajectories by combining preoperative magnetic resonance imaging with high-resolution flat detector–computed tomography imaging.1 The additional commentary and data provided by Dr. Cardinale provides further credence to the safety of this technique.2,3 The relatively young population undergoing SEEG implantation and the low occurrence of complications for cerebral angiography in this population cannot be overemphasized.

Actual Oncologic Impact of Radical Surgical Resection for Malignant Gliomas  Voir?

We enjoyed reading the recent paper by Al-Tamimi et al.1 The authors are to be congratulated for this original and striking case series, which suggests that isocitrate dehydrogenase (IDH)-mutated World Health Organization (WHO) grade II gliomas with foci of malignant transformation that have been treated by early and radical resection as first-line treatment may have adjuvant therapy postponed under a close clinical and imaging follow-up without oncologic detriment to the patient. We fully support the conclusions since we have the same experience from isolated cases (Figure 1), and we wish to discuss some of the results with the authors to extend their work.

Ideally, How Early Should Cranioplasty Be Performed—Days, Weeks, or Months Following Decompressive Craniectomy Surgery to Label as “Optimal Early Cranioplasty”? Big Enigma  Voir?

I read with great interest the article by Yang et al1 entitled “How Early Can We Perform Cranioplasty for Traumatic Brain Injury After Decompressive Craniectomy? Retrospective Multicenter Study,” published recently in your esteemed journal. In a retrospective study, the authors compared cranioplasty between 2 groups, an early group with 15 cases and a late group with 144 cases. The optimal timing of cranioplasty was judged on the basis of resolution of raised intracranial pressure features picked up on serial cranial computed tomography (CT) scans.

Anterior Transdiskal Screws  Voir?

We read with interest the article “Anterior Transdiskal Axial Screw Fixation for Subaxial Cervical Spine: A Biomechanical Study” by Zheng et al.1 The authors performed a biomechanical assessment of the strength of anterior transdiskal axial screws for subaxial cervical spine fixation. They identified that such a mode of screw fixation provides a stable construct and can be a useful technique of spinal stabilization. It is unfortunate that the authors were not able to locate our contribution to the subject.

With great interest and appreciation, we read the recent article by Li et al1 titled “Computed Tomography Angiography Spot Sign as an Indicator for Ultra-Early Stereotactic Aspiration of Intracerebral Hemorrhage.” It is important to investigate if ultra-early stereotactic aspiration can benefit patients with intracerebral hemorrhage (ICH). In Li et al's study, the authors used negative spot sign as an indicator for ultra-early stereotactic aspiration in ICH and found this strategy could benefit ICH patients with negative spot sign.

Unusual Appearance of Trigemino-Cardiac Reflex During Cerebellopontine Angle Surgery  Voir?

In a recent paper published by Shibao et al,1 they analyzed the data of 92 patients who underwent surgery using an anterior transpetrosal approach between December 2005 and June 2015 for various sizes of petroclival tumors. The trigemino-cardiac reflex (TCR) presentation in their series included bradycardia and hypotension secondary to stimulation of the trigeminal nerve region during a middle fossa approach. The TCR was observed in 14 of 92 patients (15.2%). Shibao et al1 also noted that it was related to the size of the tumor involving the Meckel cave and to the degree of tumor adhesion to the trigeminal nerve.

Neurosurgical Management in Anticoagulated Patient: Always a Challenge  Voir?

I read with interest the article “Safe Burr Hole Surgery for Chronic Subdural Hematoma Using Dabigatran with Idarucizumab” published in a recent issue of WORLD NEUROSURGERY.1 Intracerebral hemorrhage is an important cause of worldwide disability and mortality due to the increase in elderly patients and the use of oral anticoagulation. The decision to initiate anticoagulation in an elderly patient (person aged 80 years according to the World Health Organization) is complex. Several factors must be considered, among them the limitation to adherence to treatment and potential risk of falls.
