Herein, safe and reliable neuroendoscopic biopsy via an extremely narrow foramen of Monro (ENFM) for a non-hydrocephalic patient with hypothalamic and pineal region tumors was successfully applied. A 17-year-old boy presented with hypothalamic manifestations attributed to hypothalamic and pineal region tumors. Small ventricles were seen. Intraoperatively, to advance different diameter steerable fiberscopes via ENFM, the third ventricle was flushed to induce a moment increase in the intraventricular pressure with subsequent dilatation of FM...

INTRODUCTION: Hydrocephalus represents impairment in cerebrospinal fluid (CSF) dynamics. If the treatment of hydrocephalus is considered difficult, the repeated revisions of ventriculo-peritoneal (VP) shunts are even more challenging. OBJECTIVE: The aim of this article is to evaluate the efficiency of ventriculo-epiplooic (VEp) shunt as a feasible alternative in hydrocephalic patients. MATERIAL AND METHODS: A technical modification regarding the insertion of peritoneal catheter was imagined: midline laparotomy 8-10cm long was performed in order to open the peritoneal cavity; the great omentum was dissected between its two layers; we placed the distal end of the catheter between the two epiplooic layers; a fenestration of 4cm in diameter into the visceral layer was also performed...

This report describes a pregnancy with a triploid fetus identified from a scan for anomalies at 18 weeks and confirmed by amniocentesis. A 29-year-old, primigravida woman was referred to our clinic for genetic counseling at 18 weeks of gestation because of a mild oligohydramnios due to amniotic fluid index (AFI) less than the fifth percentile in her 18th week. The woman underwent amniocentesis, which revealed a karyotype of 69,XXX. There was no consanguinity in this family. In postmortem evaluation, we encountered a hydrocephalic fetus with an aberrant skull shape, including dysplastic calvaria with large posterior fontanel, marked intrauterine growth retardation (IUGR) in addition to syndactyly of third and fourth fingers, exophthalmia, cleft palate, low set malformed ears, micrognathia and club foot...

To determine the clinical value of radionuclide shuntography in the evaluation of adult hydrocephalic patients with suspected ventriculoperitoneal (V-P) shunt malfunction. All adult patients who underwent Tc-99m diethylenetriamine pentaacetic acid shuntographic scans at Far Eastern Memorial Hospital between August 2005 and December 2015 were included. Shuntographic results were visually evaluated in a simple qualitative manner: prompt flow that reached the peritoneum on 30-minute early images and diffuse peritoneal tracer distribution on 2-hour delayed images were interpreted as nonobstructive shunt flow...

Choroid plexus tumors are rare intracranial tumors which account for only 0.4-0.6% of all brain tumors. These are intraventricular papillary neoplasms derived from choroid plexus epithelium and range from choroid plexus papillomas (World Health Organisation (WHO) grade I) to choroid plexus carcinomas (WHO grade III). It is an important albeit rare cause of hydrocephalous. We present to you the case of a 1-year-old child who presented with the signs and symptoms of hydrocephalous and was diagnosed as choroid plexus papilloma on histopathology...

BACKGROUND: Cerebrospinal fluid (CSF) shunts are life-long implants, and patients have reported anecdotally on noises associated with their shunts. There is, however, a marked lack of information regarding acoustic phenomena related to CSF shunts. METHODS: We identified all patients who had been treated or followed in our neurosurgical department within a 15-year period from January 2000 up to the end of 2014. After approval of the local ethics committee all patients who were cognitively intact were explored by a questionnaire and by personal interview about acoustic phenomena related to their shunts...

PURPOSE: We investigate the effects of environmental enrichment (EE) on morphological alterations in different brain structures of pup rats submitted to hydrocephalus condition. METHODS: Hydrocephalus was induced in 7-day-old pup rats by injection of 20% kaolin into the cisterna magna. Ventricular dilatation and magnetization transfer to analyze myelin were assessed by magnetic resonance. Hydrocephalic and control rats exposed to EE (n = 10 per group) were housed in cages with a tunnel, ramp, and colored plastic balls that would emit sound when touched...

The correlation between hydrocephalus and Chiari type I malformation (CIM) has been debated since Chiari's first descriptions of CIM but some studies have shown that CIM and hydrocephalus (HCP) could cause symptoms/disease of each other or vice versa. Recent research has found that treatment focused on hydrocephalus with ventricle enlargement also provides alleviation of CIM and even of syringomyelia. However, the lack of consensus among previous studies left unanswered the question of how endoscopic third ventriculostomy (ETV) addresses CIM and why it fails...

Hydrocephalus is usually associated with functional deficits which can be assessed by neurobehavioral tests. This study characterizes the neurobehavioral deficits occurring with increasing duration and severity of ventriculomegaly in an experimental neonatal hydrocephalic rat model. Hydrocephalus was induced in three weeks old albino rats by intracisternal injection of kaolin while controls received sterile water injection. They were sacrificed in batches at one, four and eight weeks post-injection after neurobehavioral tests (forelimb grip strength, open field and Morris water maze tests) were performed...

Why a catheter can be correctly placed in the ventricle by inserting perpendicular to the frontal bone on the ventricular drainage? We performed a study on the accuracy of a path perpendicular to the skull surface into the anterior horn using computed tomography (CT), and a clinical study. Twenty patients were studied on CT images. Using the curved multi-planar reconstruction method, the curved frontal skull and brain were reconstructed to flat structures, and perpendicular lines were drawn from the flat surface to the foramen of Monro on the reconstructed images...

INTRODUCTION: We examined mortality, dementia, and progression of hydrocephalic symptoms among untreated individuals with idiopathic normal-pressure hydrocephalus (iNPH) in a population-based sample. METHODS: A total of 1235 persons were examined between 1986 and 2012. Shunted individuals were excluded. We examined 53 persons with hydrocephalic ventricular enlargement (probable iNPH: n = 24, asymptomatic or possible iNPH: n = 29). Comparisons were made with individuals without hydrocephalic ventricular enlargement...

BACKGROUND: Improved shunt survival and a better understanding of factors related to failure in paediatric hydrocephalus still pose a challenge for neurosurgeons, in order to avoid morbidity and mortality, as well as the economic impact of repeated revision surgeries. 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...

INTRODUCTION: Shunt disconnection (SD), or migration of the distal end to extra-peritoneal tissues, may lead to shunt malfunction or be diagnosed incidentally. We present a systematic approach for treatment options that is tailored to each patient's personalized history, CSF physiology, and distribution (MRI), as well as a careful informed consent process. METHODS: We present two algorithms, for symptomatic and asymptomatic SD. In cases presenting with symptomatic elevated intracranial pressure, a distal shunt revision (DSR), or, in selected patients, an endoscopic third ventriculostomy (ETV), should be performed...

Follow-up observation is required for mild-to-moderate hydrocephalic patients because of the potential damage to brain. However, effects of mild-to-moderate hydrocephalus on gray and white matter remain unclear in vivo. Using structural MRI and diffusion tensor imaging (DTI), current study compared the cortical thickness and white matter integrity between children with mild-to-moderate communicating hydrocephalus and healthy controls. The relationships between cortical changes and intelligence quota were also examined in patients...

The authors report on a patient harbouring an unruptured cortical arteriovenous malformation (AVM), who had presented with obstructive hydrocephalus due to compression of the cerebral aqueduct by a large venous varix. A ventriculoperitoneal (VP) shunt was inserted in emergency. Due to its large volume, the AVM was not referred for treatment and a follow-up policy was chosen. After the second VP shunt dysfunction, endoscopic third ventriculostomy was performed under neuronavigation. The procedure went uneventfully and the patient recovered well...
