Many strokes from a single non-stenosing plaque: from the last event a light to the first one?

Introduction: Large artery atherosclerosis is a relevant cause of ischemic stroke. Beyond carotid artery stenosis ≥ 50%, causative in etiological classification of stroke, non-stenosing plaques are an increasingly reported cause of stroke with embolic pattern.

Methods: We are presenting the case of a 56 years old woman presenting with a first symptomatic multifocal ischemic stroke in the right internal carotid artery (ICA) territory on 2018 and a finding of asymptomatic past vascular injury in the same vascular territory on neuroimaging studies.

Trigeminal Pontine Sign: From Imaging to Diseases Beyond Trigeminal Neuralgia.

The so-called trigeminal pontine sign has been described as a marker of different diseases, from multiple sclerosis to herpetic infections. First, it has been proposed as linear hyperintensity in the pons on the Magnetic Resonance Imaging (MRI) of patients with multiple sclerosis and trigeminal neuralgia. After these descriptions, it has been reported as incidental findings in the same patients and in patients with HSV or VZV infections.

Double strike without stroke: a postpartum headache with too many causes.

Introduction: Pregnancy and postpartum are phases in the women's life where the thrombotic risk is increased both on the venous and on the arterial side.

Methods: We are presenting the case of a young woman at the third pregnancy, carried out without complications until delivery, whose postpartum was characterized by the occurrence of headache. Neuroimaging studies were performed, firstly brain computed tomography (CT) with CT Angiography and after brain Magnetic Resonance Imaging (MRI) with MR Angiography.

Post-infectious central nervous system vasculitides in adults: an underdiagnosed and treatable disease part II. Neuroimaging of selected etiologies : Part II. Neuroimaging of selected etiologies.

Introduction: As detailed in the first part of this review, post-infectious vasculitides are a wide and complex category, including several clinical, microbiological and neuroradiological patterns. In order to raise the suspicion for diagnosis, the knowledge of two different neuroradiological issues is needed, i.e.

Post-infectious central nervous system vasculitides in adults: an underdiagnosed and treatable disease : Part I. Overview.

Introduction: The differential diagnosis of Primary Central Nervous System Angiitis (PACNS) is complex and includes several inflammatory and non-inflammatory conditions. Among the first ones, post-infectious CNS vasculitides represent a relevant topic and they are often underdiagnosed.

Aims: The main aim of this review is to summarize the clinical and neuroimaging features of post-infectious vasculitides, highlighting the diagnostic clues and the need to carefully consider them in the differential diagnosis of PACNS.

Intravenous thrombolysis in young adults with ischemic stroke: A cohort study from the international TRISP collaboration.

Background And Aims: Previous observational data indicate that young adults treated with intravenous thrombolysis (IVT) for acute ischemic stroke have more favorable outcomes and less complications when compared to older adults. Given the limited data on this topic, we aimed to provide more evidence on clinical outcomes and safety in such patients, using a large international thrombolysis registry.

Methods: In this prospective multicenter study, we used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry from 1998 to 2020.

Middle cerebral artery fenestration with a contralateral early branching investigated through magnetic resonance angiography: an embryological view on an incidental finding.

Purpose: Middle cerebral artery (MCA) anomalies are a small group of congenital variants, including fenestration, duplication and Twig-like MCA. Some other variants, i.e.

Premorbid frailty, stress hyperglycemia ratio, and functional outcome in patients with acute ischemic stroke.

Background: Frailty, defined as multidimensional prognostic index (MPI), has been recently identified as strong predictor of disability and mortality in the elderly with acute ischemic stroke (AIS). The stress hyperglycemia ratio (SHR) is a recently introduced biomarker significantly associated with poor outcome in AIS.

Objectives: This study aimed to investigate in what extent frailty, measured by MPI, and SHR affects the 3-months outcome of patients > 65 years-old with AIS.

Endovascular therapy in patients with acute intracranial non-terminal internal carotid artery occlusion (ICA-I).

Background: Acute intracranial occlusion of the internal carotid artery (ICA) can be distinguished into (a) occlusion of the terminal ICA, involving the proximal segments of the middle or anterior cerebral artery (ICA-L/-T) and (b) non-terminal intracranial occlusions of the ICA with patent circle of Willis (ICA-I). While patients with ICA-L/-T occlusion were included in all randomized controlled trials on endovascular therapy (EVT) in anterior large vessel occlusion, data on EVT in ICA-I occlusion is scarce. We thus aimed to evaluate effectiveness and safety of EVT in ICA-I occlusions in comparison to ICA-L/-T occlusions.

Acute Encephalopathies in SARS-CoV-2 Infection: A Clinical and Neuroimaging Perspective.

Neurological manifestations are frequent in patients with SARS-CoV-2 infection and can be correlated with different pathogenic mechanisms which can be divided into two categories: direct invasion of the central nervous system by the virus and indirect effects deriving from the severity of the systemic infection and by the inflammatory response correlated with cytokine storm. Among the neurological manifestations, acute encephalopathy is very frequent and its nomenclature has recently been updated. The occurrence of a condition of altered mental status, reduced consciousness, delirium up to coma represents an element associated with a greater severity of the infection and mortality both in an Intensive Care Unit setting and in an Emergency Department setting.

Pathophysiology of COVID-19-Related Extrapyramidal Disorders.

Coronavirus disease 2019 (COVID-19) has been associated with a variety of neurological manifestations (i.e., anosmia, ageusia, myalgia, headache) and neurological syndromes (i.

Two novel compound heterozygous HOXB1 variants in congenital facial palsy: A case report and a brief review of the literature.

Hereditary congenital facial palsy (HCFP) is a medical condition caused by dysfunction of the seventh cranial nerve. HCFP is characterized by feeding difficulties and dysmorphic features in the orofacial region. In some cases hearing loss, strabismus, limb malformations, and musculoskeletal defects may be associated.

Contrast-Induced Encephalopathy: A Case Series Analysis.

Background: Contrast-induced encephalopathy (CIE) is a rare adverse event linked to intravascular use of iodine-containing contrast media. The prevalence of CIE could increase in the future due to growing numbers of endovascular procedures. We provide insights from a case series of 7 patients.

Neurovascular Issues in Antiphospholipid Syndrome: Arterial Vasculopathy from Small to Large Vessels in a Neuroradiological Perspective.

Antiphospholipid syndrome (APS) is an autoimmune prothrombotic condition characterized by venous thromboembolism, arterial thrombosis, and pregnancy morbidity. Among neurological manifestations, arterial thrombosis is only one of the possible associated clinical and neuroradiological features. The aim of this review is to address from a neurovascular point of view the multifaceted range of the arterial side of APS.

Expanding the Neurological Phenotype of Anderson-Fabry Disease: Proof of Concept for an Extrapyramidal Neurodegenerative Pattern and Comparison with Monogenic Vascular Parkinsonism.

Anderson-Fabry disease (AFD) is a genetic sphingolipidosis involving virtually the entire body. Among its manifestation, the involvement of the central and peripheral nervous system is frequent. In recent decades, it has become evident that, besides cerebrovascular damage, a pure neuronal phenotype of AFD exists in the central nervous system, which is supported by clinical, pathological, and neuroimaging data.

Statin use and long-term risk of recurrent intracerebral haemorrhage: the MUCH-Italy.

Background: Whether statin use after spontaneous intracerebral haemorrhage (ICH) increases the risk of recurrent ICH is uncertain.

Methods: In the setting of the Multicentric Study on Cerebral Haemorrhage in Italy we followed up a cohort of 30-day ICH survivors, consecutively admitted from January 2002 to July 2014, to assess whether the use of statins after the acute event is associated with recurrent cerebral bleeding.

Results: 1623 patients (mean age, 73.
