BACKGROUND: The surgical methods of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VS) for patients with noncommunicating hydrocephalus have rapidly increased in the past 2 decades. However, there is controversy regarding the efficacy and safety of these 2 surgical methods for noncommunicating hydrocephalus. The purpose of this study was to identify whether ETV is safer and more efficacious than VS for patients with noncommunicating hydrocephalus. METHODS: We performed electronic searches in PubMed, Embase, China National Knowledge Internet, and the Cochrane Library to identify studies published up to February 03, 2018...

PURPOSE: Phase-contrast cine magnetic resonance imaging (PC-MRI) is a widely used technique for determination of possible communication of arachnoid cysts (ACs). Three-dimensional (3D) sampling perfection with application-optimized contrasts using different flip-angle evolutions (3D-SPACE) technique is a relatively new method for 3D isotropic scanning of the entire cranium within a short time. In this research, the usage of the 3D-SPACE technique in differentiation of communicating or noncommunicating type ACs was evaluated...

OBJECTIVE The clinical course of high-grade central nervous system gliomas is occasionally complicated by hydrocephalus. The risks of shunt placement and clinical outcome following CSF diversion in this population are not well defined. METHODS The authors retrospectively reviewed the outcomes of patients with pathologically confirmed WHO grade III or IV gliomas with shunt-treated hydrocephalus at their institution. Outcomes of patients in this cohort were compared with those of patients who underwent shunt treatment for normal pressure hydrocephalus (NPH)...

BACKGROUND: Entrapment of the temporal horn, known as isolated lateral ventricle (ILV), is a rare type of noncommunicating focal hydrocephalus, and standard treatment has not been established. We report 2 cases of endoscopic surgery for ILV and highlight the anatomic surgical nuances to avoid associated surgical risks. CASE DESCRIPTION: The first patient presented with recurrent ILV following initial shunt placement for ILV, owing to shunt malfunction. In the second patient, ILV recurred secondary to choroid plexus inflammation caused by cryptococcal infection...

Endoscopic third ventriculostomy (ETV) is a common treatment for noncommunicating hydrocephalus. Although rare, vascular injury and traumatic pseudoaneurysm development during ETV have been reported. The authors present the case of a 13-year-old boy who underwent repeat ETV (rETV) for shunt and ETV failure, and who suffered an intraoperative subarachnoid hemorrhage due to iatrogenic injury to the basilar tip, with subsequent development of a pseudoaneurysm. Despite initial primary coil embolization, the aneurysm recurred and was definitively treated with flow diversion...

We present a pediatric case of a rapidly expanding third ventricle germ cell tumor (GCT). A 14-year-old boy suffered from gradual-onset central diabetes insipidus (DI) and received desmopressin treatment. Magnetic resonance imaging (MRI) showed nonspecific findings of the pituitary-hypothalamic axis. Nine months after the initial DI diagnosis, he developed progressively worsening headache. MRI demonstrated a third ventricle tumor causing noncommunicating hydrocephalus, although an MRI 16 weeks before admission did not show the lesion...

OBJECTIVE The pathophysiology of chronic noncommunicating hydrocephalus (ncHC) is poorly understood. This present study explored whether lessons about the pathophysiology of this clinical entity might be retrieved from results of overnight monitoring of pulsatile and static intracranial pressure (ICP) and ventricular infusion testing. METHODS The study cohort included adult patients (> 20 years of age) with chronic ncHC due to aqueductal stenosis in whom symptoms had lasted a minimum of 6 months. A reference cohort consisted of age- and sex-matched patients managed for communicating HC (cHC)...

A patient with Klippel-Feil syndrome presented with hydrocephalus secondary to intraventricular hemorrhage. Fusion of the cervical vertebrae may have impeded cerebrospinal fluid flow. Change in the properties of cerebrospinal fluid flow after hemorrhage may have induced noncommunicating hydrocephalus. Endoscopic third ventriculostomy was effective for the treatment of hydrocephalus associated with Klippel-Feil syndrome.

INTRODUCTION: There have been no reports of occult medulloblastoma nor noncommunicating hydrocephalus due to radiologically occult brain tumors. Herein, we report radiologically occult medulloblastoma with noncommunicating hydrocephalus. CASE REPORT: A 3-year-old boy presented with macrocephaly, visual field constriction, and papilledema. Neuroimagings showed enlargement of the ventricles without any mass lesions. The CT cisternography did not show influx of the contrast into the ventricles, which suggested local cerebrospinal fluid (CSF) circulatory disturbance at the outlet of the fourth ventricle...

Background and purpose Enlargement of the subarachnoid spaces in infancy (ESSI) is a common cause of macrocephaly without proven explanation. We have observed subarachnoid diffusion to be decreased in these patients. We aim to quantify the diffusivity of ventricular and subarachnoid cerebrospinal fluid in ESSI patients, to determine if diffusion characteristics deviate from normocephalic infants, and to propose a unique mechanism for ESSI. Materials and methods 227 consecutive brain magnetic resonance exams from different macrocephalic children were retrospectively reviewed after institutional review board waiver...

BACKGROUND: Hydrocephalus is classified as noncommunicating and communicating based on whether all ventricular and subarachnoid spaces are communicating. Although the diagnosis between the two different states is crucial, it is difficult in certain conditions. In particular, communicating hydrocephalus and noncommunicating hydrocephalus owing to fourth ventricle outlet obstruction are highly misdiagnosed. We describe a case of fourth ventricle outlet obstruction of unknown origin that was initially misdiagnosed as communicating hydrocephalus...

Neuromyelitis optica is an inflammatory disease characterized by neuritis and myelitis of the optic nerve. Its physiopathology is connected with the aquaporin-4 water channel, since antibodies against aquaporin-4 have been found in the cerebrospinal fluid and blood of neuromyelitis optica patients. The seropositivity for aquaporin-4 antibodies is used for the diagnosis of neuromyelitis optica or neuromyelitis optica spectrum disease. On the other hand, aquaporin-4 is expressed in astrocyte feet in the brain-blood barrier and subventricular zones of the brain ventricles...

BACKGROUND: Glioblastoma patients can develop hydrocephalus, either obstructive, typically at diagnosis as a result of mass effect, or communicating, usually later in the disease. OBJECTIVE: To characterize the indications and efficacy of ventriculoperitoneal (VP) shunting for patients with glioblastoma-associated hydrocephalus. METHODS: Retrospective review was conducted of 841 glioblastoma patients diagnosed from 2004 to 2014, 64 (8%) of whom underwent VP shunting for symptomatic hydrocephalus, to analyze symptoms and outcomes after shunting...

Entrapment of the temporal horn is a rare form of noncommunicating focal hydrocephalus. Standard treatment has not yet been established for this condition, and only a few cases have been reported in the literature. The authors reviewed their cases of temporal horn entrapment treated between May 2013 and December 2014 and report their experience with endoscopic temporal ventriculocisternostomy. Four patients were identified (3 adults and 1 child) who underwent this treatment. In 3 patients, the condition developed after tumor resection, and in 1 patient it developed after resection of an arteriovenous malformation...

BACKGROUND: Treatment of low-pressure hydrocephalus (LPH) may require prolonged external ventricular drainage (EVD) at sub-zero pressures to reverse ventriculomegaly. Endoscopic third ventriculostomy (ETV) has been used in the treatment of noncommunicating hydrocephalus; however, indications for ETV are expanding. METHODS: Patients with the diagnosis of LPH as defined by the Pang and Altschuler criteria who underwent sub-zero drainage treatment over an 8-year period were included...

REVIEW
Vijetha V Maller, Richard Ian Gray
Noncommunicating hydrocephalus is often referred to as obstructive hydrocephalus and is by definition an intraventricular obstruction of cerebrospinal fluid flow. Patient symptoms depend on the rapidity of onset. Acute obstructive hydrocephalus causes sudden rise in the intracranial pressure, which may lead to death, whereas in chronic hydrocephalus there may not be any symptoms. Computed tomography and magnetic resonance imaging play important roles in the diagnosis and management of hydrocephalus. Advances in magnetic resonance imaging such as the 3D sequences and phase-contrast imaging have revolutionized the preoperative and postoperative assessment of noncommunicating hydrocephalus...

Hydrocephalus basically means an increase in the volume of cerebrospinal fluid (CSF) and the ventricles. As simple as it may sound, the definition and classification of hydrocephalus have been a matter of debate over many decades. Many international neurosurgical and radiological workgroups have tried to develop a consensus and over the last 5-10 years have been able to put forth a more well-defined and standardized approach. Though, the debate and controversy surrounding this topic is expected to continue, we have tried to review the most recent and consensually accepted definition and classification...

CONTEXT: Endoscopic third ventriculostomy (ETV), wherein a stoma is created in the floor of the third ventricle, has now become the standard procedure for noncommunicating hydrocephalus across the world. However, in certain situations, this procedure may pose technical difficulties. These include a narrow prepontine space, vascularized third ventricular floor, the presence of prominent blood vessels traversing within the prepontine space, significant basal exudates, thickened and ill-defined third ventricular floor, and distorted floor anatomy...

Lumbar puncture is a safe and commonly performed procedure, with an overall complication rate of 0.1% to 0.5%. Well-known contraindications to lumbar puncture are an intracranial tumor, noncommunicating hydrocephalus, coagulopathy, and ruptured aneurysm with subarachnoid hemorrhage. We report a case of a young man with epilepsy who, after a lumbar puncture performed for research purposes, presented with an intracerebral hematoma and neurological deficits. To the best of our knowledge, post-tap intraparenchymal hematoma is extremely rare and only 1 case has been reported previously...
