RESUMO

Neurocysticercosis is a rarely diagnosed but significant clinical problem from infestation with taenia solium. It occurs as a result of ingestion of infested pork and the mode of transmission is usually feco-oral. It is commonly associated with non-specific neurologic manifestations expected of intracranial space-occupying lesions with its most common neurological presentation being seizures. However, its diagnosis without seizure is rarely reported. We report a recent experience in this regard and outcome of this disease which was inadvertently managed surgically. A good history and high index of suspicion especially in developing and low socioeconomic region is helpful for diagnosis in the presence of appropriate radiological findings. Prognosis is good when treatment is tailored to well selected cases. Treatment options include medical with or without surgical removal of encapsulated cyst. A high index of suspicion will be helpful in making appropriate diagnosis and proper management of this disease.

RESUMO

Background: Aneurysmal Subarachnoid Haemorrhage (aSAH) is a vascular injury with significantly high mortality, especially when poorly managed. This study seeks to outline the experiences in setting up a neurovascular service in Lagos, Nigeria. Methods: A series of 45 patients were operated after aSAH over a period of 10 years. Patients consecutively were recruited following computed tomography angiography (CTA) diagnosis of aSAH. Clinical data were recorded on a predesigned form after obtaining informed consent; aSAH was classified using the WFNS classification, intraoperative findings were documented. Challenges in the management were analysed in a post-operative root cause analysis (RCA) review. Outcomes and factors responsible for the observed outcomes and actions taken were recorded. Results: Forty-five patients were operated after aSAH was confirmed; there were 29 females and 16 males. (M:F 1:1.8), the age ranged from 14 to 76 years (mean 49.1±13.58). All the aneurysms were on the anterior circle of Willis, mainly on Anterior Communicating Artery aneurysm (18/48).Thirty-eight patients (84.4%) survived and were discharged within an average of 10 days after surgery. Lower GCS at presentation was associated with poor prognosis (p = 0.026); however, data analysis demonstrated that other factors (financial issues, lack of appropriate instrumentation and equipment, experience of the surgeon) played a significant role in determining the outcome. Conclusions: Aneurysmal Subarachnoid Haemorrhage (aSAH) is a challenging pathology and its management may be further burdened in resource constrained countries, as shown by the data analysed in this study from Lagos, Nigeria. Specialized and well-funded Neurovascular centres are needed to overcome the challenges faced and to improve care for aSAH patients in Nigeria.

RESUMO

Background: Intracranial subdural empyema (SDE) is a seemingly uncommon life-threatening ailment with varying presentations and outcomes. A variety of risk factors have been associated with predisposition to intracranial SDEs; however, they may be cryptogenic. There is an increased predilection for intracranial SDE in children and teenagers with paranasal sinusitis or middle ear infections. The clinical presentation is non-specific and thus a high index of suspicion is required. Neuroimaging is an invaluable diagnostic tool for early diagnosis and surgical intervention. There have been multiple proponents for either burr hole or craniotomy to treat intracranial SDEs; however, despite surgical intervention, adverse neurologic sequelae and even mortality still occur. Extended antibiotic therapy is mandatory and impacts significantly on patients' outcomes. Objectives: This study describes the demographics, clinical presentation, and surgical outcomes in patients with intracranial SDEs over the study period. Design: This is a retrospective single-centre case series. Setting: This study takes place in a tertiary referral centre, university hospital. Materials and Methods: This was a retrospective review of patients presenting with intracranial SDEs over a 10-year period in a tertiary neurosurgical unit serving south-western Nigeria. Demographic, clinical, and radiologic data were retrieved from patient records. Results: Forty-nine patients presented with intracranial SDEs during the review period. These patients aged between 16 months and 75 years, most of whom were 20 years of age and below. The mean age was 21.37 ± 19.29 years with a median age of 15 years. There were 35 males and 14 females giving a male-to-female ratio of 2.5:1. The most common presentations were headache (73.5%), altered sensorium (55.1%), and seizures (38.8%). Forty patients (81.6%) had evacuation of SDE by burr hole and subdural washout. There was a significant post-op residual SDE in six patients. There were eight (16.3%) mortalities in this series. Forty-seven (95.9%) patients had sterile cultures of the subdural pus collection. Conclusion: Intracranial SDE affects mostly children and teenagers. Early diagnosis, emergent surgery, extended antibiotic therapy, and concurrent source control employing a multidisciplinary approach are essential in managing this condition. Burr hole and subdural washout help control the disease process, reduce operation time, and may yield outcomes similar to craniotomies, which are more invasive.

RESUMO

BACKGROUND: Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt; however, there is growing evidence that endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) is an alternative. OBJECTIVE: To compare the success rate and morbidity of ETV with CPC and ventriculoperitoneal shunt (VPS) as the primary treatment of hydrocephalus in patients with myelomeningocele. METHODS: A prospective study from January 2016 to February 2019, involving 46 patients with myelomeningocele who developed hydrocephalus after repair in a tertiary hospital in southwestern Nigeria. Biodata and preoperative features of hydrocephalus were documented. ETV + CPC or VPS was done using standard operative techniques. Patients were followed up monthly for 6 mo. RESULTS: There were 23 patients in the ETV + CPC arm and 22 patients in the VPS arm. Morbidities were cerebrospinal fluid leak, 8.3% in the ETV + CPC arm and 4.5% in the VPS arm, wound dehiscence, 13.6% in the VPS arm, none in the ETV + CPC arm. At 6-mo follow-up, success rate for ETV + CPC was 60.9% and 59.1% for VPS, P = .9. CONCLUSION: ETV + CPC had similar success rate with VPS at 6 mo with lower morbidity. ETV + CPC should be considered a viable alternative when treating patients with myelomeningocele and hydrocephalus.

RESUMO

Context: Congenital brain anomalies are of diverse types however few are seen in clinical practice. They are associated with high morbidity and mortality; prompt diagnosis and management aid in mitigating some of their adverse effects. Magnetic resonance imaging (MRI) is ideal for imaging these conditions, especially in pediatric cases due to its lack of ionizing radiation and excellent soft-tissue delineation. Not much literature exists for Nigeria due to challenges with statistics and record keeping. Aim: The aim of this study is to document the common congenital brain anomalies encountered using MRI in our environment. Settings and Design: A 5-year retrospective study of all pediatric brain MRI conducted and reviewed in Lagos University Teaching Hospital. 73 pediatric brain MRI scans were reviewed. Materials and Methods: Morphologic evaluation of all pediatric brain MRI conducted in the last 5 years (March 2012­February 2016) was reviewed, retrospectively, by three independent radiologists. Clinical presentations were also documented. Statistical Analysis Used: Descriptive statistics was done using SPSS: PASW Statistics for Windows, Version 18.0 Results: Seventy-three pediatric brain MRI scans were conducted in the last 5 years with congenital brain anomalies seen in 19 (26.0%) of the cases. Their ages ranged from 3 months to 17 years with a mean age of 6.7 ± 6.1 years. There were 9 (47.4%) males and 10 (52.6%) females. The common anomalies are congenital hydrocephalus 7 (35%), of which aqueductal stenosis was 6 (32%), arteriovenous malformations 3 (16%), cerebral atrophy 3 (16%), and arachnoid cysts 2 (11%). Predominant clinical features were delayed developmental milestones, macrocephaly, seizures, headaches, and vomiting. Conclusion: The common congenital brain anomalies in our environment are congenital hydrocephalus, aqueductal stenosis, arteriovenous malformations, cerebral atrophy and arachnoid cysts. MRI is useful in evaluating these anomalies; early diagnosis and prompt intervention can be offered to mitigate adverse effects
