PURPOSE: To assess the role of perfusion-related signal decay on diffusion kurtosis imaging (DKI) estimates for in vivo stratification of glioma according to the integrated approach of the 2016 World Health Organization classification of tumors of the central nervous system (2016 CNS WHO). METHODS: In this study 77 patients with histopathologically confirmed glioma were retrospectively assessed between January 2013 and February 2017 in a prospective trial. Mean kurtosis (MK) and mean diffusivity (MD) metrics from DKI were assessed by two physicians blinded to the study from a volume of interest around the entire solid tumor...

Differential diagnosis of acute and subacute transverse myelopathy includes inflammatory, infectious, vascular, metabolic and paraneoplastic etiologies. Information on the diagnostic approach to transverse myelopathy with regard to daily clinical practice is provided. The differentiation between five lesion patterns on magnetic resonance imaging (MRI) in myelitis may be helpful: (1) longitudinal extensive transverse myelitis, (2) short segment ovoid or peripherally located, (3) "polio-like", (4) granulomatous and (5) segmental with rash...

BACKGROUND AND PURPOSE: The estimates on the risk of rupture of intracranial aneurysms remain a controversial topic. Circumferential aneurysmal wall enhancement (CAWE) on vessel wall magnetic resonance imaging (MRI) has been described in unstable aneurysms. Sentinel headaches and third nerve palsy are possible symptoms prior to the rupture of intracranial aneurysms. In this study, we aimed to demonstrate that CAWE could be associated with these symptoms. METHODS: We performed a retrospective analysis of consecutive symptomatic or asymptomatic patients with unruptured intracranial aneurysms who were examined by high-resolution MRI from October 2014 to November 2016...

Neurodegeneration with brain iron accumulation (NBIA) is a heterogeneous group of inherited neurologic disorders with iron accumulation in the basal ganglia, which share magnetic resonance (MR) imaging characteristics, histopathologic and clinical features. According to the affected basal nuclei, clinical features include extrapyramidal movement disorders and varying degrees of intellectual disability status. The most common NBIA subtype is caused by pathogenic variants in PANK2. The hallmark of MR imaging in patients with PANK2 mutations is an eye-of-the-tiger sign in the globus pallidus...

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...

PURPOSE: Susceptibility-weighted imaging (SWI) visualizes small cerebral veins with high sensitivity and could, thus, enable quantification of hemodynamics of deep medullary veins. We aimed to evaluate volume changes of deep medullary veins in patients with acute cerebral venous sinus thrombosis (CVST) over time in comparison to healthy controls. METHODS: All magnetic resonance imaging (MRI) experiments were executed at 3 T using a 32-channel head coil. Based on SWI and semiautomatic postprocessing (statistical parametric mapping [SPM8] and ANTs), the volume of deep medullary veins was quantified in 14 patients with acute CVST at baseline and the 6‑month follow-up, as well as in 13 healthy controls undergoing repeated MRI examination with an interscan interval of at least 1 month...

Intracranial schwannomas are common but intra-suprasellar schwannomas are extremely rare. We represent the case of a 57-year-old woman with an intra-suprasellar tumor that was presurgically diagnosed as an anterior clinoidal meningioma. Intraoperatively it adhered tightly to the internal carotid artery wall and could not easily be dissected, possibly leading to profuse hemorrhage and sacrifice of the carotid artery with coil embolization. Histopathology demonstrated a schwannoma. We reviewed and summarized the clinical, imaging, and intraoperative findings of previously reported intra-suprasellar schwannomas...

PURPOSE: During endovascular treatment of intracranial aneurysms using coils, migration is a serious complication that increases neurological morbidity. The aim of this experimental study was to assess the effectiveness and complications of retrieving volume coils with different, currently available clot retrievers in a porcine model. METHODS: Volume coils of three-dimensional (3D) shape and different sizes were placed in the axillary artery of pigs. By means of 4 different clot retrievers (Trevo ProVue; Solitaire FR; 3D-Separator; ERIC) a total of 40 retrieval maneuvers (10 per retriever) were performed by deploying the retrievers within the migrated coils and trying to trap parts of the coils by advancing the microcatheter...

BACKGROUND AND PURPOSE: In unenhanced computed tomography (CT) of acute ischemic stroke, the density of occluding clots is associated with the content of red blood cells and successful recanalization with stent thrombectomy. However, no CT marker for fibrin content is established. In order to improve clot diagnostics, we conducted an in vitro study to investigate thrombus composition of histologically defined ovine blood clots with unenhanced and contrast-enhanced CT using spectral detector CT (SDCT)...

OBJECTIVE/BACKGROUND: We have anecdotally observed patients with high-flow ventral cerebrospinal fluid (CSF) leaks resulting from penetrating osseous spicules or calcified discs to be relatively thin. The purpose of this study was to explore the validity of this observation and determine if a potential association exists between low body mass index (BMI) and high-flow spinal ventral CSF leaks resulting from such dura-penetrating lesions. METHODS: Sixteen consecutive patients with precisely localized high-flow ventral spinal CSF leaks on dynamic myelography were identified...

PURPOSE: Most recent guidelines recommend the use of stent retriever devices in endovascular treatment of acute ischemic stroke with large vessel occlusion (LVO). Recently published data reported convincing results with thromboaspiration devices such as the Penumbra System (Penumbra, Alameda, CA, USA) combined with supple reperfusion catheters by using the ADAPT (A Direct Aspiration First-Pass Thrombectomy) technique. The aim of this study was to report our initial experience with the 3MAX (3...

PURPOSE: There is limited information available on the incidence of in-stent stenosis (ISS) secondary to the use of flow-diverting stents in the intracranial vasculature. We sought to determine the incidence, severity, and clinical course of ISS on angiographic follow-up after treatment of saccular aneurysms with p64. METHODS: We retrospectively reviewed all patients who underwent treatment of a saccular (ruptured and unruptured) intracranial aneurysm with ≥1 p64 between 2011 and 2015...

PURPOSE: To evaluate arterial spin labeling (ASL) perfusion and dynamic contrast-enhanced (DCE) perfusion in glioma grading according to the previous WHO classification of 2007, as well as concerning isocitrate dehydrogenase (IDH) mutation status and ATRX expression as required by the new WHO 2016 brain tumor classification. METHODS: The mean values of Ktrans, Kep, Ve, and Vp by DCE perfusion, and cerebral blood flow (CBF) by ASL perfusion were assessed retrospectively in 40 patients with initial glioma diagnosis...

OBJECTIVE: To illustrate the added value of flat-detector computed tomography angiography with intravenous contrast media injection (intravenous FDCTA) in the evaluation of complex A1/A2/AcomA aneurysms. PATIENTS AND METHODS: We retrospectively reviewed 15 patients with ruptured aneurysms. In each patient, an intravenous FDCTA was performed and its diagnostic value investigated. RESULTS: In all patients, FDCTA contributed relevant additional information concerning the anatomy of the A1/A2/AcomA complex and the relationship of the aneurysm neck to these vascular structures, which could not be gained by 2D- and 3D-DSA, and changed the management in 33% of the patients (5 out of 15)...
