Craniopharyngiomas are benign epithelial tumors which may very occasionally recur in ectopic locations. We present two cases of ectopic recurrence, both in the posterior fossa, and provide a review of the literature with basic statistics. Two patients admitted to our institution with posterior fossa lesions underwent gross total resection.

Methods: A total of 29 pediatric patients diagnosed with UVH or BVH were included in this study. In UVH, a neuroendoscopic SPT was performed (sometimes accompanied by NEFPFMO).
In the late 1980s, craniofacial surgery units reported suboptimal cosmetic results, cranial volume restriction, and intracranial hypertension after anterior cranial vault remodeling in bilateral coronal synostosis associated with severe brachyturricephaly. A possible explanation was a severe associated growth restriction of the posterior calvaria with radiological synostosis at the lambda sutures. "Conventional" or "fixed" posterior cranial vault expansion techniques were developed to address these limitations, sometimes as the first surgical step in a two-staged protocol of total calvarial reconstruction, combined with suboccipital decompression in cases of symptomatic cerebellar tonsillar herniation or, more easily, to resolve the characteristic occipital flattening of lambdoid synostosis.

Current literature suggests that the topic requires more examination. An insight into this condition is limited by a lack of universally agreed-upon diagnostic criteria, heterogeneity of published series, the multitude of different management options and misunderstanding of relationships among pathophysiological mechanisms involved.

Methods: A cross-sectional study was performed between 2015 and 2018. Parents of pediatric patients with PHH attending our neurosurgery outpatient clinic were invited to complete the HOQ-sv and to enroll in the study.
Background: Every year, there are an estimated 22.6 million new neurosurgical consultative cases worldwide, of which 13.8 million require surgery.

The presence of external cerebrospinal fluid (CSF) leakage is infrequent and very few authors have reported about surgical complications.

Case Report: We report the case of a 9-year-old child with an extensive suprasellar ganglioglioma presenting with a cerebral infarction due to direct compression of the medium cerebral artery.
Purpose: Shunt independence remains a matter of debate for neurosurgeons, and little information on this subject is available in the literature. The aims of the study were to analyse the incidence of shunt removal in a series of paediatric patients and to describe our experience with attempts at shunt removal.
Methods: Thirty of 212 paediatric patients shunted between 2000 and 2016 at our institution were studied for shunt independence.
Surgery for intraventricular tumors remains a controversial and evolving field, with endoscopic resection becoming more popular. We present a series of nine consecutive cases of purely endoscopic resection of intraventricular tumors with the aid of an ultrasonic aspirator specific for neuroendoscopy. Nine patients (five men, four women) aged 18-74 years (mean 43.

METHODS The authors performed this cross-sectional study between March 2015 and April 2016. All the parents of a pediatric patient with hydrocephalus who attended the Hospital Regional Universitario de Málaga neurosurgery outpatient clinic were invited to enroll in the study and complete the HOQ-Spanish version.

For these reasons, an analysis is performed on the factors related to the first shunt failure in the long-term follow-up of a series in a single centre.
Methods: A retrospective review was conducted on 166 hydrocephalic paediatric patients shunted for the first time between 2000 and 2014.
Somatostatin analogs (SSA) are the mainstay of pharmacological treatment for pituitary adenomas. However, some patients escape from therapy with octreotide, a somatostatin receptor 2 (sst2)-preferring SSA, and pasireotide, a novel multi-sst-preferring SSA, may help to overcome this problem. It has been proposed that correspondence between sst1-sst5 expression pattern and SSA-binding profile could predict patient's response.

Although first shunt survival rates and complications have been studied by several teams, much less is known about survival and complications of subsequent systems. The goals of this study were to evaluate the surgical outcome in a series of pediatric patients followed for a long time and establish the differences between first and subsequent extracranial shunt survival and complications.

The study's main objectives were to prospectively evaluate the effectiveness and safety of 5-ALA when used in clinical practice setting on high-grade gliomas' patients.
Methods: National, multicenter and prospective observational study.

Aims: Here, we tested the hypothesis that glial responses via the production of cytokines such as transforming growth factor-beta 1 (TGFβ1) and tumour necrosis factor alpha (TNFα), which play important roles in neurodegenerative diseases, are correlated with the severity of congenital hydrocephalus in the hyh mouse model. We also searched for evidence of this association in human cases of primary hydrocephalus.
Methods: Hyh mice, which exhibit either severe or compensated long-lasting forms of hydrocephalus, were examined and compared with wild-type mice.
Among the prognostic factors when it comes to patients with high-grade gliomas, we find the radicality of the surgery performed. The limitations of this factor are caused by either the extension of the tumour or its location in an eloquent area. To achieve this goal, in the last few years we have developed several methods that allow us to maximise tumour resection, while always trying to cause the least possible co-morbidity.

Different definitions of ETV success, hydrocephalus aetiology or patient age at diagnosis may influence the outcome of the ETV procedure. The aim of this work was to analyse our clinical series and to examine the influence of different factors on ETV outcome.

Their management remains controversial, but histopathologic diagnosis after complete or partial resection must be performed to differentiate these tumors from other multiple cerebral lesions. Three cases of multicentric glioma are presented, one of which had supra- and infratentorial lesions.

The present investigation was designed to obtain evidence whether or not ependymal denudation occurs in 16- to 40-week-old human fetuses developing a communicating hydrocephalus (n = 8) as compared to fetuses of similar ages with no neuropathologic alterations (n = 15). Sections through the walls of the cerebral aqueduct and lateral ventricles were processed for lectin binding and immunocytochemistry using antibodies against ependyma, astroglia, neuroblasts, and macrophages markers.
