PURPOSE: Pediatric intraventricular tumors of the third ventricle are among the most difficult-to-treat brain tumors. Recently, endonasal endoscopic surgery for suprasellar, third ventricle, and median clivus lesions has become the common procedure, and its indications are expanding to pediatric cases. We describe our strategy for endonasal endoscopic surgery for pediatric third ventricle tumors. METHOD: We report on surgical anatomies and our surgical procedures in detail, including case presentations...

BACKGROUND: Neural tube defects (NTD), such as spina bifida, are surgically treatable and primarily preventable non-communicable diseases. How incidence, mortality and disability-adjusted life year (DALYs) rates of NTD have modulated over time is not well defined. Correspondingly, the aim of this study was to quantitively define the global, regional, and national epidemiological trends in these. METHODS: A retrospective review of data from the Global Burden of Disease Study 2019 Database was performed...

Colloid cysts of the third ventricle are benign intracranial lesions that account for 0.5 to 2% of all brain tumors and are even rarer in pediatric population. Dandy was the first to successfully excise a colloid cyst of the third ventricle via a transcortical transventricular approach in 1921. For several decades to follow, the transcortical transventricular and transcallosal microsurgical approaches remained the cornerstone of surgical management of these lesions. With time and refinements in endoscopic equipment and techniques, endoscopic resection of colloid cysts evolved into a currently well-established and appealing minimally invasive alternative to microsurgery...

BACKGROUND: Medulloblastoma is the most common malignant primary pediatric brain tumor. Over the years, an increase in published research has been observed on this topic. However, there is a lack of analysis on the characteristics and trends and the socioeconomic indicators associated with medulloblastoma research productivity and impact. METHODS: The Scopus database was used to search all articles from inception to 2020. Bibliometric information was obtained from Scopus, and bibliometrics diagrams were created using VOSviewer software...

BACKGROUND: Artery of Percheron (AOP) as main feeder artery of arteriovenous malformation (AVM) is extremely rare. Two cases of thalamic AVM fed by AOP have been reported to date and only one AVM been removed by microsurgery when attempt of intervention embolization failed. Midbrain AVM fed by AOP has not been reported yet. CASE PRESENTATION: Here, we presented the first successful embolized case of midbrain AVM supplied by the AOP in a 10-year-old boy, who suffered dual oculomotor nerve palsy and secondary hemorrhage before embolization...

INTRODUCTION: Vein of Galen malformation (VOGM) is an exceptionally uncommon form of congenital intracranial vascular malformations. It is highly unusual for this lesion to spontaneously thrombose. The clinical presentation of a patient may range from being asymptomatic to critically ill. The underlying pathophysiological mechanisms that cause spontaneous thrombosis are still poorly understood. METHODS AND RESULTS: The literature on spontaneous thrombosis of VOGM was systematically reviewed, analyzed, and summarized with a focus on its pathophysiology, types, clinical presentations, diagnosis, management, and outcomes...

INTRODUCTION: The treatment of hydrocephalus accounts for 40% of all procedures in pediatric neurosurgery. Ventriculoperitoneal shunt placement is the treatment of choice for most patients. When contraindicated due to different abdominal complications, the use of a ventriculoatrial shunt is a safe second option. Nevertheless, this procedure is not without risk of complications. An extremely rare complication is the displacement of the distal catheter by a central venous catheter. CASE REPORT: We present two atypical cases of shunt dysfunction related to the placement of a central venous catheter...

BACKGROUND: Tumors of the choroid plexus of the third ventricle are uncommon. Surgical excision is technically challenging because of the rich vascularisation, central location, and high incidence in young children. Open microsurgical resection is considered the standard treatment. However, attempts at purely endoscopic removal of choroid plexus tumors of the third ventricle have also been made in the past, with encouraging results. CASE REPORTS: We report our experience with endoscopic ultrasonic removal of two cases of tumors of the third ventricular choroid plexus...

Pontine gliomas represent difficult to treat entity due to the location and heterogeneous biology varying from indolent low-grade gliomas to aggressive diffuse intrinsic pontine glioma (DIPG). Making the correct tumor diagnosis in the pontine location is thus critical. Here, we report a case study of a 14-month-old patient initially diagnosed as histone H3 wild-type DIPG. Due to the low age of the patient, the MRI appearance of DIPG, and anaplastic astrocytoma histology, intensive chemotherapy based on the HIT-SKK protocol with vinblastine maintenance chemotherapy was administered...

OBJECTIVE: Due to evidence for proton beam therapy (PBT) in pediatric central nervous system (CNS) tumors, compact proton therapy systems became commercially available to allow better integration in a hospital setting. However, these systems have a non-zero magnetic field at the level of the patient. Often, these patients have a cerebrospinal fluid shunt, and most of them are adjustable through a magnet. Whether the induced magnetic fields could interfere with adjustable shunts is unknown...

Paediatric intracranial aneurysms are rare entities accounting for less than 5% of all age intracranial aneurysms. Traumatic aneurysms are more common in children and have an association with anatomical variations such as arterial fenestrations. Here, we present a case of a child initially presenting with traumatic subarachnoid haemorrhage who returned to baseline and was discharged home only to return within 2 weeks with diffuse subarachnoid and intraventricular re-haemorrhage. A dissecting aneurysm of a duplicated (fenestrated) V4 vertebral artery segment was identified as a rare cause of rebleeding...

BACKGROUND: Spinal atypical teratoid rhabdoid tumor (AT/RT) is an extremely rare tumor and represents less than 2% of all AT/RTs. METHODS: Available medical literature on spinal AT/RT in English was retrieved from PubMed and comprehensively reviewed. Clinical presentation, diagnosis, management, prognosis, and outcome in patients with spinal AT/RT have been elucidated by citing a case of extradural AT/RT of the cervicodorsal spine. RESULTS: The age at presentation is usually less than 3 years...

BACKGROUND: Gorlin-Goltz syndrome is a rare autosomal dominant disorder resulting from PTCH1 gene mutation and presents with variable clinical manifestations. The co-occurrence of medulloblastoma and cardiac fibroma in Gorlin-Goltz syndrome is extremely rare. The present article discusses a patient diagnosed with Gorlin-Goltz syndrome and concurrent medulloblastoma and cardiac fibroma. CASE PRESENTATION: A 19-month-old boy transferred to our hospital after a radiological finding of posterior fossa lesion and hydrocephalus...

Many tools and techniques have been developed to obtain maximal safe tumoral resection in neurosurgery. Fluorescent dyes, including sodium fluorescein, have become also part of this armamentarium to localize the lesion and its boundaries peroperatively. Considering its alleged safety profile and its ability to diffuse in areas of altered blood-brain barrier, a typical characteristic of a number of both benign and malignant pediatric tumors, sodium fluorescein may appear an ideal candidate as intraoperative adjunct in pediatric neurosurgery...

PURPOSE: We tested the role of age and sex in surgery following pediatric TBI hospitalization. METHODS: Records of 1745 children hospitalized at a pediatric neurotrauma center in China included age, sex, cause of injury, diagnosis of injury, days of hospitalization, in-house rehabilitation, Glasgow Coma Scale score, mortality, 6-month post-discharge Glasgow Outcome Scale score, and surgery intervention. The children were 0-13 years (M= 3.56 years; SD = 3.06), with 47...

Cerebellar mutism syndrome (CMS) is a well-known complication of posterior fossa (PF) tumour surgery. CMS has previously been reported in cases of non-tumour surgical aetiology in a limited number of publications. We report a case of a 10-year-old girl who suffered a cerebellar haemorrhage and subsequent CMS following surgical treatment of a ruptured arteriovenous malformation (AVM) in the cerebellar vermis. The AVM was removed acutely through a transvermian access, and hydrocephalus was treated with temporary external drainage...

PURPOSE: The purpose of this study is to determine whether patients with unoperated craniosynostosis have different frontal sinus pneumatization than unaffected controls. METHODS: Retrospective review was performed between 2009 and 2020 of previously unoperated patients with craniosynostosis older than 5 years old at first presentation to our institution. Total frontal sinus volume (FSV) was calculated using 3D volume rendering tool in Sectra IDS7 PACS system...
