PURPOSE: Small meningiomas causing hydrocephalus without obstruction of the ventricular system are rare. Herein, we report a case of small clinoidal meningioma with communicating hydrocephalus, which resolved after tumor removal. CASE PRESENTATION: A 70-year-old woman presented with a 1-month history of memory disturbance followed by gait disturbance. MR images revealed a right clinoidal meningioma, 2 cm in diameter, and dilatation of the ventricles suggesting communicating hydrocephalus...

A wide range of pathologies can cause papilloedema. Vestibular schwannoma is a benign and slow-growing tumour that causes symptoms and findings on ophthalmic examination when the diagnostic is delayed. The authors report a case of a 64-year-old male who presented with bilateral disc oedema secondary to a vestibular schwannoma grade 4. Obstructive hydrocephalus was not evident. The authors suggest that cerebrospinal fluid protein may have a role in the formation of optic disc oedema. A right suboccipital craniectomy was performed to remove the tumour, leading to secondary facial palsy...

BACKGROUND: Primary diffuse leptomeningeal primitive neuroectodermal tumor (PDL PNET) is extremely rare, with only 19 cases reported in the literature to date. We present a case of a child with rapidly progressive PDL PNET and a literature review. A 10-year-old boy presented with mood lability, hallucinations, generalized pain, enuresis, and headaches. Initial investigation failed to produce a diagnosis. The symptoms progressed to seizure, back pain, and papilledema. Imaging showed acute hydrocephalus and mild diffuse leptomeningeal enhancement without an identifiable primary lesion...

A 4-year-old-boy required emergent craniectomy and drainage of a large right-sided acute subdural hematoma after head trauma, during which massive sinus hemorrhage with brain swelling occurred. Acute intraoperative management entailed dural cover using synthetic dural membrane substitute and scalp coverage over the herniated brain using acellular dermal matrix. After intensive monitoring and control of raised intracranial pressure over the next few days, the exposed brain was then covered by scalp and forehead flaps with cadaveric skin grafting to the donor site...

BACKGROUND: Primary intracranial anaplastic gangliogliomas are rare tumors in the pediatric patient group. Most of them present with symptoms of elevated pressure or symptomatic epilepsy. Extraaxial location is far more common than axial location. On MRI examination, they mimic pilocytic astrocytomas. The outcome after surgery depends mainly on the possible amount of surgical resection, and oncological therapy is necessary to prevent recurrence of the disease. CASE REPORT: An 11-year-old boy presented with headache and double vision due to obstructive hydrocephalus...

BACKGROUND/AIM: To explore the theory of 'growing into deficits', a concept known from developmental neurology, in a series of cases with chronic hydrocephalus (CH). METHODS: Patients were selected from the Amsterdam Dementia Cohort and underwent extensive dementia screening. RESULTS: Twelve patients with CH were selected, in whom Alzheimer's disease was considered unlikely, based on biomarker information and follow-up. Mean Mini-Mental State Examination score was 24 (range 7-30)...

BACKGROUND: Sarcoidosis is a chronic, multisystem disease characterised by non-necrotising granulomatous inflammation of unknown aetiology. Most commonly, the lungs, lymph nodes, skin and eyes are affected in sarcoidosis; however, nervous system involvement occurs in approximately 5%-15% of cases. Any part of the nervous system can be affected by sarcoidosis. CASES: Herein we describe three unusual patient presentations of neurosarcoidosis, one with optic neuritis, a second with hydrocephalus and a third with cervical myelopathy...

We report the case of a 72-year-old patient presenting in our ICU with persistent postoperative coma in a context of recent unexplored neurological dysfunction. Detailed medical history taking from the patient's family revealed he recently suffered from gait instability, urinary incontinence, and slight cognitive impairment. These constituted the clinical triad of normal pressure hydrocephalus syndrome. The presence of normal cerebrospinal fluid (CSF) pressure and distinctive radiological findings confirmed the diagnosis of normal pressure hydrocephalus or Hakims-Adams syndrome...

We report the case of a 41-year-old female with neurofibromatosis Type 1 (NF1) who developed a rosette-forming glioneuronal tumor (RGNT) in the tectal plate. This tumor was diagnosed in 2002 when the patient presented with obstructive hydrocephalus, which was subsequently treated with a ventriculoperitoneal shunt and then an endoscopic third ventriculostomy. Initially thought to be a pilocytic astrocytoma, it was followed with serial magnetic resonance imaging (MRI) until tumor progression and development of a large fourth ventricular cystic component prompted resection via suboccipital craniotomy...

A 61-year-old woman presented with a 10-month history of gait disturbance and a 7-month history of urinary incontinence. The Hasegawa dementia scale-revised score indicated cognitive impairment. Brain magnetic resonance imaging (MRI) indicated hydrocephalus with disproportionately enlarged subarachnoid space. This is usually considered a characteristic finding in idiopathic normal pressure hydrocephalus (iNPH). Ventriculo-peritoneal shunting improved the patient's symptoms. Neurosarcoidosis was suspected as a cause of the hydrocephalus because of the abnormalities in the cerebrospinal fluid and the abnormal enhancement of the cauda equina, the leptomeninges of the brainstem, and the spinal cord, as seen on MRI with gadolinium enhancement...

BACKGROUND: Choroid plexus papillomas (CPPs) are rare benign intracranial tumors. Here, we report a rare case of CPP presenting with typical symptoms of normal-pressure hydrocephalus not with obstructive hydrocephalus. CASE DESCRIPTION: A 45-year-old female presented with a 6-year history of headache and typical symptoms of normal-pressure hydrocephalus (NPH) such as gait disturbance, urinary incontinence, and cognitive dysfunction in addition to the more common symptoms of choroid plexus papillomas (CPP), such as lower cranial nerve dysfunctions and ataxia...

BACKGROUND: Patients presenting with the classical idiopathic normal pressure hydrocephalus (iNPH) triad often show additional parkinsonian spectrum signs. Accurate differential diagnosis strongly influences the long-term outcome of cerebrospinal fluid (CSF) shunting. OBJECTIVE: The aim of this study was to find potential CSF microRNA (miRNA) biomarkers for NPH mimics with parkinsonian syndromes that can reliably distinguish them from iNPH patients. METHODS: Two cohorts of 81 patients (cohort 1, n = 55; cohort 2, n = 26) with possible iNPH who were treated in two centers between January 2011 and May 2014 were studied...

The nonoperative management of sylvian fissure dermoid/epidermoid cysts presents a risk that is difficult to quantify. With rupture, potentially fatal complications such as chemical meningitis, hydrocephalus, fever, seizure, or meningeal irritation may occur. In this paper, we present an asymptomatic case of such a cyst with imaging evidence of prior rupture, and we review the literature for the likelihood of future complications. We use for illustration a case of a 68-year-old woman with imaging features of a sylvian fissure epithelial inclusion cyst who refused surgical intervention and review the literature for further investigation...

Spinocerebellar ataxia 15 (SCA15) is a clinically heterogeneous movement disorder characterized by the adult onset of slowly progressive cerebellar ataxia. ITPR1 is the SCA15 causative gene. However, despite numerous reports of genetically-confirmed SCA15, phenotypic uncertainty persists. We reviewed the phenotypes of 60 patients for whom SCA15 was confirmed by the presence of a genetic deletion involving ITPR1. The most prevalent symptoms were gait ataxia (88.3%), dysarthria (75.0%), nystagmus (73.3%), and limb ataxia (71...

Neurosurgeons increasingly use decompressive craniectomy (DC) in neurocritical care. In this review, the authors summarize the topic of DC for the neurointensivist. Following a brief overview of the procedure, the major indications for the procedure are described. This includes a review of the literature regarding well-established indications, such as infarction and traumatic brain injury, as well as lesser known indications, including intracerebral hemorrhage, ruptured cerebrovascular malformations, sinus thrombosis, and infection...

OBJECTIVE Glioblastoma multiforme (GBM) is composed of cells that migrate through the brain along predictable white matter pathways. Targeting white matter pathways adjacent to, and leading away from, the original contrast-enhancing tumor site (termed leading-edge radiosurgery [LERS]) with single-fraction stereotactic radiosurgery as a boost to standard therapy could limit the spread of glioma cells and improve clinical outcomes. METHODS Between December 2000 and May 2016, after an initial diagnosis of GBM and prior to or during standard radiation therapy and carmustine or temozolomide chemotherapy, 174 patients treated with radiosurgery to the leading edge (LE) of tumor cell migration were reviewed...

OBJECTIVE Craniopharyngioma (CP) adherence strongly influences the potential for achieving a radical and safe surgical treatment. However, this factor remains poorly addressed in the scientific literature. This study provides a rational, comprehensive description of CP adherence that can be used for the prediction of surgical risks associated with the removal of these challenging lesions. METHODS This study retrospectively analyzes the evidence provided in pathological, neuroradiological, and surgical CP reports concerning 3 components of the CP attachment: 1) the intracranial structures attached to the tumor; 2) the morphology of the adhesion; and 3) the adhesion strength...

OBJECTIVE There is a paucity of literature regarding the learning curve associated with performing endoscopic endonasal cranial base surgery. The purpose of this study was to determine to what extent a learning curve might exist for endoscopic endonasal resection in cases of craniopharyngiomas. METHODS A retrospective review was performed for all endoscopic endonasal craniopharyngioma resections performed at Thomas Jefferson University from 2005 to 2015. To assess for a learning curve effect, patients were divided into an early cohort (2005-2009, n = 20) and a late cohort (2010-2015, n = 23)...

OBJECTIVE When complete resection of craniopharyngioma is not achievable or the sequelae are prohibitive, limited surgery and radiation therapy have demonstrated excellent local disease control while minimizing treatment-related sequelae. When residual tissue exists, there is a propensity for further cyst development and expansion during and after radiation therapy. This can result in obstructive hydrocephalus, visual changes, and/or clinical decline. The authors present a quantitative analysis of cyst expansion during and after radiotherapy and examine how it affected subsequent management...
