RESUMO

BACKGROUND: The resection of the jugum (planum) sphenoidale meningioma (JSM) is challenging, and there is a scarcity of available data in the literature. This study aimed to describe the surgical management and long-term outcome of jugum sphenoidale meningioma. METHODS: This was a retrospective, single-center, cohort study of 91 JSM patients treated in our department from 2005 to 2022. All the included patients have undergone surgical treatment. Clinical, radiologic, and surgical data were extracted with specific attention to the age at onset, family history, duration from symptoms to diagnosis, clinical presentation, quality of excision, recurrence, and treatment outcome. RESULTS: WHO grade I and grade II meningioma were 83.5% (n = 76) and 16.5% (n = 15) respectively. Fronto-lateral 42.9% (n = 39) and pterional approaches 57.1% (n = 52) were the 2 major surgical approaches used for the management of planum sphenoidale meningioma. Twelve patients needed emergency surgical treatment at admission: 4 (4.4%) External CSF Shunt and 8 (8.8%) VP-Shunt. We have found a statistically significant (P = 0.032) association between the quality of excision and the risk of recurrence. The GTR (Hazard ratio = 1) of the planum meningioma protects the patient from recurrence within 60 months of follow-up. Postoperative complications encountered were CSF-Leak in 2.2%, Meningitis 4.4%, surgical site infection 2.2%, and surgical site hematoma 3.3%. The overall postoperative favorable outcome was 68.1% (n = 62). CONCLUSIONS: The pterional approach has allowed the achievement of GTR for jugum sphenoidale meningioma with protective odds from recurrence risk.

RESUMO

Background: This study aims to appraise aneurysm scores and ratios' ability to discriminate between ruptured aneurysms and unruptured intracranial aneurysms (UIAs) in subarachnoid hemorrhage (SAH) patients harboring multiple intracranial aneurysms (MICAs). We, then, investigate the most frequent risk factors associated with MICAs. Methods: We retrospectively applied unruptured intracranial aneurysm treatment score (UIATS) and population hypertension age size of aneurysm earlier SAH from another aneurysm site of aneurysm (PHASES) score, aspect, and dome-to-neck ratio to the 59 consecutive spontaneous SAH patients with MICAs admitted between January 2000 and December 2015 to the Department of Neurosurgery of the University Hospital Center "Hôpital des Spécialités" of Rabat (Morocco). Patients with at least two intracranial aneurysms (IAs) confirmed on angiography were included in the study. Results: Fifty-nine patients were harboring 128 IAs. The most frequent patient-level risk factors were arterial hypertension (AHT) 30.5 % (n = 18) and smoking status 22.0 % (n = 13). A PHASES score recommended treatment in 52 of 60 ruptured aneurysms and in six of 68 UIAs with a sensitivity of 31.67% and a specificity of 76.47%. UIATS recommended treatment in 26 of 62 ruptured aneurysms and in 35 of 55 UIAs with a sensitivity of 41.9% and a specificity of 63.6%. Aspect ratio recommended treatment in 60 of 60 ruptured aneurysms and in 63 of 68 UIAs with a sensitivity of 100% and a specificity of 88.24%. Dome-to-neck ratio recommended treatment in 45 of 60 ruptured aneurysms and in 48 of 68 UIAs with a sensitivity of 80% and a specificity of 63.24%. The aspect ratio (area under the curve [AUC] = 0.953) AUC > 0.8 has a higher discriminatory power between ruptured aneurysms and UIAs. Conclusion: AHT and smoking status were the most common risk factors for intracranial multiple aneurysms and the aspect ratio and PHASES score were the most powerful discrimination tools between ruptured aneurysms and the UIAs.

RESUMO

Background: Cystic bone echinococcosis accounts for 0.5-4% of all reported cases, and 45% occur in the spine. Our aim was to review the clinical and radiological features, surgery, and outcomes for 39 patients with recurrent spinal hydatidosis. Methods: Thirty-nine reports of patients with recurrent spinal hydatidosis (2011-2020) were followed for an average of 9.28 ± 5.60 months. Results: Lesions occurred in descending order in the; lumbar (48.7%), thoracic (43.6%), and cervical spine (7.7%). Total cyst resection was achieved in 28 of 39 patients (71.8%). Intraoperative cyst rupture occurred in 13 patients (33.3%). The postoperative American Spinal Injury Association (ASIA) score was "good" in 82% of patients. Those with "poor" postoperative ASIA scores had a 41% incidence of recurrent thoracic hydatid cysts; further, they demonstrated significantly higher recurrence rates if cysts had ruptured intraoperatively (P = 0.001). In addition, laminectomy, subtotal original cyst resection (P < 0.007), and a thoracic location were all significantly associated with higher recurrence rates (P < 0.04). Conclusion: The majority of patients demonstrated improvement following surgery for cervical hydatid cysts. Notably, those with poor outcomes typically experienced intraoperative ruptures of their thoracic hydatid cysts, contributing to high cyst recurrence rates.

RESUMO

Liagmentum flavum hematoma (LFH) is a rare cause of radiculopathy and low back pain, sharing similar symptomatology with disc herniation. It predominantly affects the lumbar thoracic spine. The underlying mechanism of LFH remains unclear; however, surgical removal of the hematoma has consistently demonstrated excellent outcomes. The objective of this case report is to emphasize the significance of diagnosing LFH. We present a surgically confirmed lumbar LFH case that mimicked a lumbar tumor, highlighting the challenges encountered during diagnosis and subsequent management.

RESUMO

Background: Spinal cord compression (SCC) is a severe consequence of multiple myeloma (MM). Surgical management is appropriate when there are spinal instability and neurological function compromise. The reversibility of peripheral neuropathy during treatment of MM has been reported in some studies after a cycle of Bortezomib (Velcade), Thalidomide, and Dexamethasone (VTD), but very rare in myeloma patients with SCC. Case Description: We report a case of a 58-year-old male tetraplegic secondary to cervical SCC by MM who completely recovered after 5 cycles of VTD chemotherapy without surgery. Conclusion: Surgical spinal cord decompression by laminectomy is known as the gold standard for treating this condition. Nevertheless, some patients can completely recover from nervous insult without surgery.

RESUMO

BACKGROUND: Over the last decade, many advancements have been made in the management of low-grade gliomas (LGGs). Overall survival outcomes are correlated with factors such as postoperative residual volumes and specific tumor biomolecular profiles such as IDH mutation status. It is unclear whether these advancements have benefited LGG patients in Africa. This scoping review protocol outlines how the authors will evaluate the epidemiology, presentations, management and outcomes of LGGs in Africa. METHODS: MEDLINE, Embase and African Journals Online will be searched from database inception to date in order to identify the relevant studies. Patients of all ages with histologically and/or radiologically confirmed LGGs that were managed in an African country will be included. Surgical and chemoradiation management of LGG tumours will be considered. Original research, reviews, commentaries, editorials and case reports will be included. RESULTS: Primary outcomes of the review will include LGG management, morbidity and mortality. Secondary outcomes include epidemiology and recurrence of LGGs. DISCUSSION: This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research as well as health system strengthening efforts by policymakers and stakeholders. SCOPING REVIEW REGISTRATION: The protocol has been registered on the Open Science Framework (OSF; registration link: https://doi.org/10.17605/OSF.IO/E732G). HIGHLIGHTS: LGGs account for 17% to 22% of total brain tumours and have a median survival time between 5.6 and 13.3 years.Despite many recent advancements in the management of LGGs, there is a paucity in the data within the African landscape.This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research and policymaking efforts.

RESUMO

INTRODUCTION: Despite recent advancements in the management of low-grade gliomas (LGGs), there is a paucity in the data within the African landscape. We aim to evaluate the epidemiology, management, and outcomes of LGGs in Africa. METHODS: Systematic searches of MEDLINE, Embase and African Journals Online were performed from database inception to January 27, 2021, for studies reporting on LGGs in Africa. Pooled statistics were calculated using measures of central tendency and spread. RESULTS: 554 unique studies were identified, of which 25 were included. The mean age of patients was 15.7 years (95% confidence interval (CI): 11.8-19.6) and 56.4% were male (95% CI: 55.6-62.6%). Most patients had solitary lesions (86.0%, 95% CI: 82.8-89.1%) located in the infratentorial region (71.6%, 95% CI: 66.1-77.1%). Most LGGs received histopathological diagnosis (71.7%, 95% CI: 69.2-74.2%) and astrocytoma was the most common type (81.1%, 95% CI: 78.5-83.7%). 37 patients had awake surgery (3.1%, 95% CI: 2.0-4.0%) and there were no reports of molecular pathology testing, intraoperative neuroimaging, or 5-aminolevulinic acid. Gross total resection was achieved in 74.8% (95% CI: 69.6-80.0%) and there was a recurrence rate of 1.7% (95% CI: 0.9-2.4%), with a mean follow-up of 19.4 months (95% CI: 6.9-31.9). CONCLUSION: LGGs are underreported in Africa. We found a lag in the uptake of techniques established in high-income countries for improving patient outcomes. Future efforts will require further training and funding in molecular pathology testing and advanced surgical adjuncts.

RESUMO

Introduction: Intracranial suppurations account for a significant proportion of intracranial masses in low- and middle-income countries (LMICs), particularly among children. The development of better imaging equipment, antibiotics, and surgical techniques has enabled significant progress in detecting and treating intracranial abscesses. However, it is unclear whether these advances are accessible and utilised by LMICs. In this review, we aimed to describe the landscape of paediatric intracranial suppurations in LMICs. Methods: This scoping review was conducted using the Arksey and O'Malley framework. MEDLINE, EMBASE, WHO Global Index Medicus, AJOL and Google scholar were searched for relevant articles from database inception to January 18th, 2021. Publications in English and French were included. Results: Of the 1,011 records identified, 75 were included. The studies, on average, included 18.8 (95% CI = 8.4-29.1) children (mean age: 8.2 years). Most children were male (62.2%, 95% CI = 28.7-95.7%). Intracranial suppurations were most commonly (46.5%) located in the supratentorial brain parenchyma. The most prevalent causative mechanism was otitis (37.4%) with streptococcus species being the most common causative organism (19.4%). CT scan (71.2%) was most commonly used as a diagnostic tool and antibiotics were given to all patients. Symptoms resolved in 23.7% and improved in 15.3% of patients. The morbidity rate was 6.9%, 18.8% of patients were readmitted, and the mortality rate was 11.0%. Conclusion: Most intracranial suppurations were complications of preventable infections and despite MRI being the gold standard for detecting intracranial suppurations, CT scans were mostly used in LMICs. These differences are likely a consequence of inequities in healthcare and have resulted in a high mortality rate in LMICs.

RESUMO

Rationale: Interventional neurovascular procedures are effective in lowering the burden of mortality and complications resulting from aneurysmal subarachnoid hemorrhage (aSAH). Despite the wide uptake of interventional neurovascular procedures in high-income countries, access to care in low- and middle-income countries remains limited, and little is known about accessibility in Africa. In this survey, we decided to assess access to diagnostic tools and treatment of aSAH in Africa. Methodology: A Google form e-survey was distributed to African neurosurgery centers accepting responses from January 4th to March 21st 2021. Data on accessibility to diagnostic tools, treatment methodologies, and interventional neuroradiology personnel in African centers were collected. Ninety five percent confidence intervals were computed for each variable. Results: Data was received from 36 neurosurgical centers in 16 African countries (16/54, 30%). Most centers were public institutions. Ninety four percent of the centers had the necessary resources for a lumbar puncture (LP) and a laboratory for the diagnosis of aSAH. Most centers had at least one computed tomography (CT) scanner, 81% of the centers had access to CT angiography and some had access to conventional angiography. Forty seven percent of the centers could obtain a head CT within 2 h of presentation in an emergency. Sixty one percent of centers provided clipping of intracranial aneurysms whilst only 22% of centers could perform the endovascular treatment. Sixty four percent of centers did not have an endovascular specialist. Conclusion: This survey highlights health inequity in access to endovascular treatment for aSAH. Lack of diagnostic tools to identify an aneurysm and a shortfall of qualified endovascular specialists are prime reasons for this. Our findings can inform health system strengthening policies including the acquisition of equipment and capacity building in Africa.

RESUMO

The ossifying fibroma is a benign fibro-osseous tumor rarely affecting the skull base. The incidence of ossifying fibroma itself is uncommon. It is considered to be an aggressive and fast-growing bone lesion. Early detection and complete surgical removal are essential to deal with its aggressive nature and recurrence. We report a case of a 20-year-old man admitted for the management of ossifying fibroma of the orbital roof extending inside the orbit mimicking meningioma and revealed by a progressive proptosis and headache. The patient underwent surgery for the subtotal removal of the tumor with its frontal infiltration with a good outcome. All meningiomas like tumors are not meningiomas and other tumors such as ossifying fibroma might be mistaken for meningioma and even get confirmation from the pathological anatomy study. Need be for these tumors to be looked at more closely for better therapeutic decision-making.
