Objective In epilepsy, early diagnosis, accurate determination of epilepsy type, proper selection of antiseizure medication, and monitoring are all essential. However, despite recent therapeutic advances and conceptual reconsiderations in the classification and management of epilepsy, serious gaps are still encountered in day‐to‐day practice in Egy...

Gliomas are a type of brain tumor that requires accurate monitoring for progression following surgery. The Brain Tumor Reporting and Data System (BT-RADS) has emerged as a potential tool for improving diagnostic accuracy and reducing the need for repeated operations. This prospective multicenter study aimed to evaluate the diagnostic accuracy and r...

Objectives: The international league against epilepsy (ILAE) recommended the harmonized neuroimaging of epilepsy structural sequences (HARNESS-MRI) to improve the detection of epileptogenic lesions in patients with focal drug-resistant epilepsy (DRE). The application of this protocol is still limited in low-resource countries, mainly due to appare...

Background Multidisciplinary pre-surgical evaluation is vital for epilepsy surgery decision and outcomes. Resective epilepsy surgery with assisted monitoring is currently a standard treatment for focal drug resistant epilepsy (DRE). In resource-limited countries, lack of epilepsy surgery center is a huge challenge. We presented and illustrated how...

Background: Awake craniotomy (AC) is a common neurosurgical procedure for the resection of lesions in eloquent brain areas, which has the advantage of avoiding general anesthesia to reduce associated complications and costs. A significant resource limitation in low- and middle-income countries constrains the usage of AC. Objective: To review the...

Background BT-RADS is a structured reporting system of post-treatment glioma. BT-RADS category 3 carries a probability of recurrent malignancy versus treatment-related changes. The aim of this study is to evaluate the additive value of DWI and resection cavity FLAIR signal changes to BT-RADS category 3 in the prediction of tumor progression. We pro...

Background Lumboperitoneal (LP) shunting is an effective treatment option aiming at cerebrospinal fluid diversion in cases of idiopathic intracranial hypertension. Confirming the distal end position, on the other hand, could be technically difficult, especially in obese people. With minimal invasive procedures, laparoscopic-assisted placement of th...

Original Article BACKGROUND: Cranioplasty is performed after decompressive craniectomy (DC) mainly for protection of the brain and cosmetic purposes. Furthermore, cranioplasty may also improve neuronal and cognitive functions. Despite cranioplasty after DC is a common procedure, the proper timing for cranioplasty is still debatable. OBJECTIVE: This...

Background Tentorial meningiomas are uncommon entity, related to tentorium and representing 3-6% of intracranial meningiomas. Being related to surrounding vital neurovascular structures, complete surgical resection of such tumors was limited in the early stages with poor outcomes, but with the continuous improvements in microsurgery and the advent...

In epilepsy, early diagnosis, accurate determination of epilepsy type, proper selection of anti-seizure treatment, and monitoring; all are essential. However, despite recent therapeutic advances and conceptual reconsiderations in the classification and management of epilepsy, serious gaps are still encountered in day-to-day practice in Egypt as wel...

Background Primary intradural spinal arachnoid cysts are rare pathologies of uncertain etiology and variable presentation from no symptoms to myelopathy or radiculopathy according to cord or root compression. MRI with diffusion and contrast differentiates them from many pathologies. There is a lot of debate regarding when to treat and how to treat...

Background Intraoperative mapping techniques maximize safety and efficacy during perirolandic glioma resection but may induce seizures and limit the procedure. We aim to report the incidence and predictors of stimulation-induced seizures during mapping either patient is awake or under general anesthesia (GA). Methods Retrospective analysis of 64 p...

Methodology: Forty patients were randomly allocated into 4 equal groups based on LA mixture used for scalp block: Group I:received 1.5 mg/kg bupivacaine 0.25% + 5 mg/kg lidocaine 1% with 1:200,000 epinephrine. Group II:same as Group I + 8 mg dexamethasone. Group III:same as Group I + 500 mgMgSO4. Group IV:same as Group I + 8 mgdexamethasone + 500 m...

Objective: According to the 2007 WHO classification of central nervous system tumours, perivascular pseudorosettes are a “histological hallmark” of anaplastic ependymoma. However, glioblastomas may also feature perivascular pseudorosettes, and their distinction from anaplastic ependymoma may present a diagnostic challenge. Method: A 60 year old mal...

Aim: We hypothesize that re-do craniotomy for recurrent grade IV glioblastomas improves survival while preserving outcome in selected patients. Methods: A retrospective analysis was conducted of 141 patients, from a prospectively collected database from 2004 to 2014, with grade IV glioblastomas who underwent craniotomy and excision. 65 patients...

We report our institutional experience using an electromagnetic navigation system, without rigid head fixation, for awake craniotomy patients. The StealthStation® S7 AxiEM™ navigation system (Medtronic, Inc.) was used for this technique. Detailed preoperative clinical and neuropsychological evaluations, patient education and contrast-enhanced MRI (...
