REVIEW
Joachim Berkefeld, Marlies Wagner, Richard du Mesnil
After a period of stagnation due to negative results of randomized trials for patients with symptomatic stenosis, the relevance of carotid artery stenting (CAS) is increasing again. CAS has become an important and evidence-based part of interventional stroke treatment. Our ability to manage acute recanalization of carotid occlusions and other niche indications properly led some skeptical neurologists to trust in carotid intervention for elective cases as well. The evolution of CAS from initial euphoria to more realistic views under consideration of trial results and guidelines is reviewed...

OBJECTIVE: It is well-known that there is a correlation between the neuropathological grade of hippocampal sclerosis (HS) and neuroradiological atrophy of the hippocampus in mesial temporal lobe epilepsy (mTLE) patients. However, there is no strict definition or criterion regarding neuron loss and atrophy of the amygdala neighboring the hippocampus. We examined the relationship between HS and neuronal loss in the amygdala. MATERIALS AND METHODS: Nineteen mTLE patients with neuropathological proof of HS were assigned to Group A, while seven mTLE patients without HS were assigned to Group B...

OBJECTIVES: Idiopathic normal pressure hydrocephalus (iNPH) is very prevalent in aging, underdiagnosed, and represents a rare cause of reversible neurological condition. The clinical triad of iNPH - gait, cognitive and urinary symptoms - and its neuroradiological features (i.e. ventriculomegaly) are not specific and found a various neurodegenerative and/or vascular conditions. We present our iNPH standardized protocol at the Geneva University Hospitals involving a multispecialty team of behavioral neurologists, neurosurgeons, neuropsychologists, engineers, and physical therapists...

Primary intraorbital ectopic meningiomas are rare and their existence remains controversial. We present a 30-year-old female with painless, non-axial proptosis and a palpable superomedial mass. The MRI demonstrated that the mass had no optic nerve sheath or sphenoid wing involvement and was initially reported to have no intracranial extension. The patient was initially thought to have an ectopic orbital meningioma. Subsequent multidisciplinary team (MDT) consultation and further specialist review of the MRI revealed a subtle dural tail connecting to an enhancing mass in the olfactory groove...

Hemophagocytic lymphohistiocytosis (HLH) is a rare multisystem disorder characterized by proliferation and diffuse infiltration multiple organs with histiocytes, including the central nervous system (CNS). Neurological manifestations of HLH have been recognized in different studies with children, but they remain relatively ill-defined in adults with HLH. From March 2008 to October 2014, 289 adult patients with HLH were admitted to our center. Clinical, radiological, and cerebral spinal fluid (CSF) data of the patients with CNS involvement were reviewed, and a retrospective study in our single-center was carried out...

Neural stem cell (NSC) therapy is a promising treatment for traumatic brain injury (TBI). In addition, mesenchymal stem cells (MSCs) have been investigated for the treatment of TBI due to their functions in neural regeneration and their neurotrophic effect. In the present study, the safety, feasibility and biological effects of autologous MSC-derived NSC-like cell transplantation were investigated in 10 patients with severe TBI. All patients received intravenous or intrathecal injections of human NSC-like cells and were evaluated with physical and neurological examinations, routine laboratory tests and neuroradiological findings...

BACKGROUND: Spasmus Nutans (SN) is a rare pediatric ophthalmologic syndrome of nystagmus, head bobbing and abnormal head positioning. Historically, SN has been associated with underlying optic pathway gliomas (OPG); however, evidence of this is association is based primarily on a small number of isolated case reports. Prior retrospective analyses have found the rate of OPG to be less than 2%, but only intermittently utilized neuroimaging with CT, which has limited sensitivity for detection of small lesions in the optic pathway...

BACKGROUND: Coma after acute head injury is always alarming. Depending on the type of injury, immediate treatment may be life-saving. About a quarter of a million patients are treated for traumatic brain injury in Germany each year. Treatment recommendations must be updated continually in the light of advancing knowledge. METHODS: This review of treatment recommendations, prognostic factors, and the pathophysiology of coma after acute head injury is based on a 2015 German guideline for the treatment of head injury in adults and on pertinent publications retrieved by a selective search in PubMed for literature on post-traumatic coma...

Vascular events in patients with coarctation of the aorta have been extensively reported and account for the majority of morbidity and mortality in untreated patients. The exact mechanism for this association is not completely understood and may include acquired anomalies or congenital abnormalities of intracranial vessel. Here we report a case of intracranial internal carotid artery dissection with subsequent formation of acquired large carotid aneurysm in a child with severe systemic hypertension and coarctation of the aorta...

Bilateral striatal necrosis (BSN) has many causes and is characterized by unique clinical and neuroradiological features. Herein, we report a clinical and genetic analysis of three BSN cases from two independent Japanese families harboring a mitochondrial DNA (mtDNA) 14459G>A mutation located in a coding region of the NADH dehydrogenase subunit 6 gene. In the first family, two male siblings from non-consanguineous parents exhibited similar phenotypes, with infantile-onset generalized dystonia. A third sporadic case involved a male patient with a comparatively milder phenotype characterized by juvenile-onset mild truncal ataxia and parkinsonism...

BACKGROUND: Hydrocephalus develops in up to 90% of patients born with myelomeningocele. Although Endoscopic Third Ventriculostomy (ETV) is currently considered the preferred treatment for obstructive hydrocephalus, its results have been inconsistent in patients with myelomeningocele. This study focuses on clinical and radiological outcomes of ETV in children with hydrocephalus related to myelomeningocele. METHODS: Medical records of 18 paediatric patients with myelomeningocele submitted to ETV from 1998 to 2015, at the Centro Hospitalar S...

Therapy-related neurotoxicity greatly affects possibility of survival and quality of life of pediatric patients treated for cancer. Central nervous system (CNS) involvement is heterogeneous, varying from very mild and transient symptoms to extremely severe and debilitating, or even lethal syndromes. In this review, we will discuss the broad scenario of CNS complications and toxicities occurring during the treatment of pediatric patients receiving both chemotherapies and hematopoietic stem cell transplantation...

OBJECTIVE Sporadic meningiomas have been classified in many different ways. Radiographically, these lesions can be described as occurring in either typical or atypical locations. The purpose of this study was to determine if there are any histopathological differences between sporadic meningiomas that arise in these varying locations in children. METHODS The neuroimaging, histopathological findings, and clinical records in patients with sporadic pediatric meningiomas not associated with neurofibromatosis Type 2 or prior radiation therapy were retrospectively reviewed...

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological syndrome associated with various clinical conditions, such as headache, encephalopathy, and seizures. It is reversible if a prompt diagnosis is made and treatment undertaken. We report a 52-year-old male with hypertensive crisis. Progressing somnolence and an unresponsive left pupil occurred. MRI revealed an intra-axial hyperintensity of the cerebellum and brainstem and occlusive hydrocephalus suggestive of encephalitis or a tumor...

The Chiari I malformation (CM-I) is a developmental alteration of the posterior cranial fossa (PCF), radiographically defined as the descent of the cerebellar tonsils = 5 mm below the foramen magnum (FM) inside the cervical canal. Headache is the most frequent symptom associated with CM-I. The association of CM-I and neurological symptoms configures with Chiari syndrome. A rare symptom associated with Chiari syndrome is intracranial hypertension syndrome with cephalea and papilloedema-the typical findings of pseudotumor cerebri (PTC)...

BACKGROUND: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments. OBJECTIVE: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment...
