BACKGROUND: We have previously proposed that pineal cysts (PCs) may result in crowding of the pineal recess, causing symptoms due to compression of the internal cerebral veins and central venous hypertension. In the present study, we compared clinical outcome of different treatment modalities in symptomatic individuals with non-hydrocephalic PCs. METHODS: The study included all patients managed surgically for non-hydrocephalic PCs in our Department of Neurosurgery over a 10-year period...

Primary central nervous system lymphoma (PCNSL) is an extranodal Non-Hodgkin's lymphoma that is confined to the brain, eyes, and/or leptomeninges without evidence of a systemic primary tumor. Although the tumor can affect all age groups, it is rare in childhood; thus, its incidence and prognosis in children have not been well defined and the best treatment strategy remains unclear. A nine-year old presented at our department with complaints of diplopia, dizziness, dysarthria, and right side hemiparesis. Magnetic resonance image suggested a diffuse brain stem glioma with infiltration into the right cerebellar peduncle...

BACKGROUND: We would like to report a case of ruptured massa intermedia (MI) as a sequela of hydrocephalus. CASE DESCRIPTION: A single case report describing the sequelae of tumor bed hematoma after a posterior fossa hemangioblastoma resection where the patient bled three days after surgery resulting in secondary hydrocephalus and subsequently dilatation of the third ventricle which resulted in rupture of the MI. The patient was managed on emergency basis with an external ventricular drain then endoscopically with a third ventriculostomy and clot extraction...

PURPOSE: Very long-term follow-up and outcome are rare for pediatric patients with hydrocephalus and shunt operations. The aim of this study was to determine the long-term mortality rates in these patients. METHODS: Pediatric patients with first shunt operation between 1982 and 1992 were included. For each patient, time and cause of death were determined. Further, patients with first operation from 1982 to 1987 were compared to those first operated from 1988 to 1992...

Objective To compare the resolution rate of hydrocephalus after endoscopy (predominantly endoscopic third ventriculostomy [ETV]) using flexible endoscopes during a 5-year period in patients with a permeable and a nonpermeable subarachnoid space (SAS). Material and Methods We conducted a retrospective cohort study of the videos and records of 150 hydrocephalic patients chosen randomly who underwent ETV (and other endoscopic procedures) with a flexible endoscope. The patients were classified into two groups based on the neuroendoscopic findings...

It is proposed that negative central nervous system (CNS) pressure is one of the filling mechanisms of the fluid spaces of the CNS. Negative CNS pressure is caused by the combination of gravitational force and body movement. The venous system imposes pressure fluctuations on the CNS due to changes in posture and body cavity pressure. It is proposed here that filling of veins, arteries and cerebrospinal (CSF) spaces are all assisted by negative CNS pressure. Hyperemia in the CNS in response to pressure changes with movement was described in the first part of this hypothesis...

OBJECTIVE/AIM: The aim of this report was to investigate the effect of ventriculoperitoneal shunt insertion for the treatment of hydrocephalus on thyroid hormones in the first 3 months of life. METHODS: Thyroid-stimulating hormone (TSH), free T3 (fT3), and free T4 (fT4) levels were compared at 7 days (preoperatively) and at 30 and 90 days (postoperatively) after birth between 25 ventriculoperitoneal shunt-inserted hydrocephalic newborns and 20 healthy newborns. RESULTS: The TSH level at 7 days was higher in the hydrocephalic patient group (6...

BACKGROUND: In symptomatic individuals with non-hydrocephalic pineal cysts (PCs), it remains controversial what causes the symptoms. Based on magnetic resonance imaging (MRI) biomarkers, we proposed that PC-associated crowding of the pineal recess may cause central venous hypertension. The aim of this study was to compare pulsatile and static ICP in patients with PCs and chronic daily headache (CDH), and compare ICP data in PC patients with the previously identified MRI biomarkers. METHODS: All patients assessed with over-night ICP monitoring for PCs or CDH who had been ruled out for idiopathic intracranial hypertension without papilledema (IIHWOP) were retrieved from the database...

OBJECTIVE At present, endoscopic treatment is advised as the first procedure in cases of suprasellar arachnoid cysts (SSCs) with hydrocephalus. However, the appropriate therapy for SSCs without hydrocephalus has not been fully determined yet because such cases are very rare and because it is usually difficult to perform the neuroendoscopic procedure in patients without ventriculomegaly given difficulties with ventricular cannulation and the narrow foramen of Monro. The purpose of this study was to find out the value of navigation-guided neuroendoscopic ventriculocystocisternostomy (VCC) for SSCs without lateral ventriculomegaly...

Folate is vital in a range of biological processes and folate deficiency is associated with neurodevelopmental disorders such as neural tube defects and hydrocephalus (HC). 10-formyl-tetrahydrofolate-dehydrogenase (FDH) is a key regulator for folate availability and metabolic interconversion for the supply of 1-carbon groups. In previous studies, we found a deficiency of FDH in CSF associated with the developmental deficit in congenital and neonatal HC. In this study, we therefore aimed to investigate the role of FDH in folate transport and metabolism during the brain development of the congenital hydrocephalic Texas (H-Tx) rat and normal (Sprague-Dawley) rats...

OBJECTIVE: A substantial number of infants in Ethiopia suffer from hydrocephalus. Neurosurgical expertise has until recently been virtually nonexistent in the country; however, since 2006, a neurosurgery training program has been established in Addis Ababa, where hydrocephalus surgery now is performed in 3 hospitals. Our experience is that hydrocephalus is diagnosed and treatment is too late to avoid severe brain damage. Introducing routine head circumference (HC) measurements can ease the detection of hydrocephalus and thus lead to earlier diagnosis, thereby reducing the brain damage caused by the condition...

BACKGROUND: Gravitational valves (GVs) prevent overdrainage in ventriculoperitoneal shunting (VPS). However, there are no data available on the appropriate opening pressure in the shunt system when implementing a GV. We performed a retrospective analysis of hydrocephalic patients who were successfully treated with VPS which included one or more GV. METHOD: In this retrospective study in adult VPS patients with GVs, we analysed all available data, including the most recent computed tomography (CT) scans, to determine the best adjustments for alleviating any symptoms of overdrainage and underdrainage...

OBJECTIVE Endoscopic third ventriculostomy (ETV) with choroid plexus (CP) cauterization (CPC) represents a viable treatment option for congenital hydrocephalus in infants younger than 2 years. Imaging studies complement clinical data in the evaluation of treatment success or failure. The objectives of this study were to investigate novel radiographic markers-cerebrospinal fluid (CSF) turbulence and CP visualization-and their ability to reflect or predict clinical outcomes following ETV/CPC. METHODS Hydrocephalic patients younger than 2 years who were initially treated by ETV/CPC at the senior authors' institution between March 2013 and February 2014 were retrospectively reviewed...

Technical limitations restrict routine anaerobe isolation from clinical materials in resource-limited laboratories. An innovative two steps combustion candle jar technique may be suitable for such setup. This system was tried with one case of chronic osteomyelitis developed on supracondyler compound fracture. Porphyromonas spp. was isolated and identified. Vancomycin was recommended based on in vitro sensitivity test, but the leg was amputed after receiving a resistant drug gentamycin. While in another child with hydrocephalous, V-P shunt associated infection by Peptostreptococcus anaerobius was successfully controlled by sensitive drug vancomycin...

BACKGROUND: In minimally invasive endoscopic port surgery, the medium is air, and the image is clearer than in fluid. The most commonly used port is a single-channel port, which accommodates the rod lens of the endoscope and 2 microsurgical instruments. This setup decreases the freedom of movement of the 3 instruments, making the bimanual procedure difficult. We describe a novel "dual-channel" endoscopic port to facilitate a bimanual refinement procedure for removing deep-seated spontaneous intracerebral hematomas, and we demonstrate the feasibility of this method...

BACKGROUND: Previous work with 3-week hydrocephalic rats showed that white matter damage could be reduced by the calcium channel antagonist magnesium sulfate (MgSO4). We hypothesized that MgSO4 therapy would improve outcomes in ferrets with hydrocephalus induced with kaolin at 15 days. METHODS: MRI was performed at 29 days to assess ventricle size and stratify ferrets to treatment conditions. Beginning at 31 days age, they were treated daily for 14 days with MgSO4 (9 mM/kg/day) or sham saline therapy, and then imaged again before sacrifice...

Intracranial teratoma is a rare neoplasm derived from omnipotent germinal cells that can contain mesoderm, endoderm and/or ectoderm layer tissue. Histologically teratomas are characterized by abnormal structures like teeth or bone that can be further subdivided into mature and immature according to the presence of incompletely differentiated tissue. Characteristic intracranial teratomas are space-occupying lesions in the pineal region and often present with hydrocephalic symptoms due to aqueduct stenosis. A 3-year-old boy presented with a peracute hemiparesis, fatigue and speech deficit...

BACKGROUND: Mutant rodent models have highlighted the importance of the ventricular ependymal cells and the subcommissural organ (a brain gland secreting glycoproteins into the cerebrospinal fluid) in the development of fetal onset hydrocephalus. Evidence indicates that communicating and non-communicating hydrocephalus can be two sequential phases of a single pathological phenomenon triggered by ependymal disruption and/or abnormal function of the subcommissural organ. We have hypothesized that a similar phenomenon may occur in human cases with fetal onset hydrocephalus...

OBJECTIVES: Suspected cerebrospinal fluid shunt (CSF) dysfunction in hydrocephalic patients poses a diagnostic uncertainty. The clinical picture can be non-specific and CT imaging alone is not always pathognomonic. Infusion tests are an increasingly used investigation for real-time hydrodynamic assessment of shunt patency. We report the correlation between infusion test results with the quality of ventricular drain placement on CT scans in a large retrospective group of hydrocephalic patients...
