Carotid splaying, also known as the Lyre sign, is a widening of the carotid bifurcation due to the displacement of the internal carotid artery and the external carotid artery just distal to the point of divergence. This phenomenon is classically exhibited by highly vascularized carotid body tumors and, in rare cases, by cervical sympathetic chain schwannomas. Demonstration of the Lyre sign by a cervical vagal neurofibroma, however, is a unique occurrence that has not been previously documented in the literature...

Surgery in and around eloquent brain structures poses a technical challenge when the goal of surgery is maximal safe resection. Magnetic resonance imaging (MRI) has revolutionized the diagnosis and treatment of neurological disorders, but tractography still remains limited in terms of utility because of the requisite manual labor and time required combined with the high risk of bias and inaccuracy. Automated whole brain tractography (AWBT) has simplified this workflow, overcoming historical barriers, and allowing for integration into modern neuronavigation...

Grade IV glioma is the most common and aggressive primary brain tumour. Gross total resection with 5-aminolevulinic acid (5-ALA) guided surgery combined with local chemotherapy (carmustine wafers) is an attractive treatment strategy in these patients. No previous studies have examined the benefit carmustine wafers in a treatment programme of 5-ALA guided resection followed by a temozolomide-based chemoradiotherapy protocol. The objective of this study was to examine the benefit of carmustine wafers on survival in patients undergoing 5-ALA guided resection...

Bottom of sulcus dysplasias (BOSDs) are localized focal cortical dysplasias (FCDs) centred on the bottom of a sulcus that can be highly epileptogenic, but difficult to delineate intraoperatively. We report on a patient with refractory epilepsy due to a BOSD, successfully resected with the aid of a multimodal surgical approach using neuronavigation based on MRI and PET, intraoperative ultrasound (iUS) and electrocorticography (ECoG) using depth electrodes. The lesion could be visualized on iUS showing an increase in echogenicity at the grey-white matter junction...

Symptomatic spinal epidural hematoma (SSEH) following spinal surgery is rare but one of the serious complications. SSEH can leave devastating neurological consequences if missing the optimal timing for treatment. The early diagnosis of SSEH is critical to the neurologic recovery, and MRI examination can help to check the location and the scope of the hematoma and provide imaging information for surgical operation. The risk factors of SSEH can be divided into preoperative factors, intraoperative factors and postoperative factors...

BACKGROUND: Even after decades of research in the field of gliomas, the overall prognosis is still quite dismal. Several factors have been proposed that affect the outcome and survival length of patients with a glioma. Here, we present a series of 471 patients, who underwent surgical resection of their glioma at a tertiary level neurosurgical centre. MATERIALS AND METHODS: We noted retrospective data of patients' age, histological tumor grade, and whether or not intraoperative magnetic resonance imaging (MRI) was used, and assessed the survival length of these patients from the day of surgery...

OBJECTIVE Maximal safe resection is a primary objective in the management of gliomas. Despite this objective, surgeons and referring physicians may, on the basis of radiological studies alone, assume a glioma to be unresectable. Because imaging studies, including functional MRI, may not localize brain functions (such as language) with high fidelity, this simplistic approach may exclude some patients from what could be a safe resection. Intraoperative direct electrical stimulation (DES) allows for the accurate localization of functional areas, thereby enabling maximal resection of tumors, including those that may appear inoperable based solely on radiological studies...

INTRODUCTION: Multiple subpial transection (MST) has been applied to the treatment of refractory epilepsy when epileptogenic zone involves eloquent areas since 1989. However, there is a lack of data evaluating the effect of this surgical technique on the cortex as measured by Magnetic Resonance Imaging (MRI). PATIENTS AND METHODS: Ten consecutive patients (3F/7M, average age: 18.5 years) were operated on using radiating MST (average: 39; min: 19, max: 61) alone (n=3) or associated with another technique (n=7)...

Surgery is paramount in glioma management and extent of resection is an independent significant prognostic factor. However, these tumors are often invisible intraoperatively. Hence imaging plays an important role in surgical guidance. A critical literature review, using MEDLINE/PubMed service was carried out. It demonstrated a gross total resection (GTR) with neuronavigation (NNS) of 31-36%, adding 5-aminolevulinic acid or fluorescein fluorescence, or intraoperative ultrasound or MRI improved GTR to 69.1, 84...

Meningioangiomatosis (MA) is a rare benign, hamartomatous lesion within the leptomeninges and cerebral cortex. Three percent of intractable epileptic patients with tumor develop MA. It may be accompanied with neurofibromatosis type II, or it may occur sporadically. Three patients, age range of 2-16 years old, presented with episodes of seizure. The patients demonstrated no family history or stigmata of neurofibromatosis type II. Electroencephalogram (EEG) was unremarkable for epileptiform activity. Magnetic resonance imaging (MRI) revealed enhancing lesions within the frontal gyrus, the anterior cingulate gyrus, and the parietal lobe...

Introduction: There have been attempts to alter the prognosis of severe spinal cord injury in different centers, but none of which have reliably altered the outcome. Some trials use stem cells (SCs) that produced widely differing results. We hereby add our experience in our center of a surgical reconstruction of the damaged spinal cord using a mixture of SCs and Platelet-Rich Protein (PRP) with fibrin coated as a biological scaffold. Materials and Methods: Four cases of severely damaged spinal cord have been operated for neurolysis and reconstruction of the spinal cord using SCs and platelet-rich protein (PRP) with fibrin coated harvested from the peripheral circulation of the patient...
