BACKGROUND: Treating idiopathic normal pressure hydrocephalus (iNPH) with lumboperitoneal shunts (LPSs) may cause cerebrospinal fluid (CSF) overdrainage. OBJECTIVE: To investigate whether LPSs, including gravitational "add-on" and programmable pressure valves (PPVs/+GVs), reduce complications and improve outcomes. METHODS: We compared PPVs/+small lumen abdominal catheters (SLs) to PPVs/+GVs using different opening pressures for supine and standing positions...

Objective Ventricular shunts are a mainstay of hydrocephalus treatment, but the detection of its clinical failure often relies on circumstantial evidence. A direct, non-interventional method for reliably evaluating cerebrospinal fluid (CSF) function does not exist due to the difficulty of measuring in vivo flow characteristics. The objective of this study is to apply a novel method of ultrasound monitoring to characterize the oscillation observed during pulsatile CSF flow and failure states in an in vitro and cadaveric model...

Intra-abdominal metastasis (IAM) of central nervous system (CNS) tumors through ventriculoperitoneal shunt (VPS) is rare but has been previously reported (e.g., germinomas and medulloblastomas). However, there has been no previous reports in literature involving meningiomas. A case of primary rhabdoid meningioma with widespread intra-abdominal carcinomatosis after placement of a VPS in a 36-year-old man is described. The patient underwent preoperative angioembolization of the tumor, craniotomy, and surgical excision, followed by postoperative gamma knife radiosurgery...

PURPOSE: We investigated the possible beneficial effects that hyperbaric oxygen therapy could offer in different brain structures affected by ventriculomegaly in pup rats submitted to experimental hydrocephalus. METHODS: Seven-day-old Wistar rats were submitted to hydrocephalus by intracisternal injection of 10% kaolin into the cisterna magna. The animals were divided into four groups: control (n = 5); control with HBOT (3ATA/2 h/day) (n = 5); untreated hydrocephalic (n = 10); hydrocephalic treated with HBOT (3ATA/2 h/day) (n = 10)...

BACKGROUND:  Primary pineal malignant melanoma is a rare type of primary central nervous system melanoma with only 19 cases reported in the literature. CASE REPORT:  We present a case of a 53-year-old man with primary melanoma of the pineal region. He presented to the emergency department with gait unsteadiness and ataxia. Magnetic resonance imaging (MRI) revealed a 22 × 17 × 22-mm mass in the pineal region. On MRI the tumor was hyperintense in T1, isointense in T2, and on T1-weighted images with gadolinium enhancement it appeared homogeneously hyperintense with hypointense spots...

Background: Symptomatic hydrocephalus due to vertebrobasilar dolichoectasia is a rare occurrence. Case Description: We report a patient who presented with acute confusion and vomiting. Neuroimaging revealed elongated and tortuous basilar artery indenting and elevating the floor of third ventricle causing obstructive hydrocephalus. Initially, the patient was treated with external ventricular drain and then with ventriculo-peritoneal shunt. Conclusion: We suggest prompt surgical intervention upon diagnosis as a first choice of treatment in order to avoid further complications...

Memantine is a selective, non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist that has previously been shown to have neuroprotective qualities in some animal models of neurologic disease. We hypothesized that memantine therapy would improve behavioral, neuropathological, and/or biochemical outcomes in juvenile rats with kaolin-induced hydrocephalus. Three-week old rats received an injection of kaolin (aluminum silicate) into the cisterna magna. Magnetic resonance imaging was performed one week later to assess ventricle size and stratify rats to three treatment groups...

Patients presenting with spontaneous, non-aneurysmal subarachnoid hemorrhage (SAH) achieve better outcomes compared to patients with aneurysmal SAH. Nevertheless, some patients develop shunt-dependent hydrocephalus during treatment course. We therefore analyzed our neurovascular database to identify factors determining shunt dependency after non-aneurysmal SAH. From 2006 to 2016, 131 patients suffering from spontaneous, non-aneurysmal SAH were admitted to our department. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non-perimesencephalic SAH (npSAH)...

INTRODUCTION: Traumatic brain injury (TBI) in children and adolescents is a community-based medical and educational challenge world-over due to increasing urbanization and motorization. In India, children between 1 to 15 years constitute significant proportion of the total population, who are vulnerable for TBI. In developed countries, pediatric trauma mortality still represents more than half of all childhood fatalities, which is 18 times more common than brain tumors. In this study, we attempted to analyze epidemiological factors, management, and outcome of TBI in children at a tertiary care center in Pune, Maharashtra...

Although responsive neurostimulation (RNS) is approved for treatment of resistant focal epilepsy in adults, little is known about response to treatment of specific cortical targets. We describe the experience of RNS targeting the insular lobe. We identified patients who had RNS implantation with at least one electrode within the insula between April 2014 and October 2015. We performed a retrospective review of preoperative clinical features, imaging, electrocardiogram (EEG), intraoperative electrocorticography (ECoG), and postoperative seizure outcome...

Objectives  Ideal treatment of craniopharyngiomas is still controversial. Radiotherapy (RT) is considered effective for recurrences or after subtotal tumor removal (STR). About 40 to 50% of patients may experience tumor cyst expansion soon after RT; in these cases, the role of salvage surgery is debated. Design  Operative video. Setting  Tertiary care center. Participants  An 11-year-old boy diagnosed with persistent craniopharyngioma. In 2015, the patient underwent right frontotemporal craniotomy for STR at another center, complicated by panhypopituitarism...

INTRODUCTION: Focal hydrocephalus including trapped temporal horn (TTH), isolated lateral and fourth ventricles, is caused by obstruction and/or adhesion related to various etiologies. With the advent of the neuroendoscope, endoscopic procedures have become an alternative in selected cases. CASE REPORT: A 2-year-old male from a rural town in México was referred to our institution because of multiple supra- and infra-tentorial abscesses and hydrocephalus. The patient had progressive deterioration and developed bilateral trapped temporal horn related to multi-septated hydrocephalus, so we performed an endoscopic ventricular-cistern-ventriculostomy through a single right temporal burr hole...
