Vessel wall magnetic resonance imaging (VW-MRI) is a modern imaging technique with expanding applications in the characterisation of intracranial vessel wall pathology. VW-MRI provides added diagnostic capacity relative to conventional luminal imaging methods. This review explores the principles of VW-MRI and typical imaging features of various vessel wall pathologies such as atherosclerosis, dissection and vasculitis. Radiologists should be familiar with this important imaging technique given its increasing usage and future relevance to everyday practice...

Polymyalgia rheumatica (PMR) represents the most common inflammatory rheumatic disease of the elderly. It is characterized by synovitis of proximal joints and extra-articular synovial structures, along with chronic high-grade systemic inflammation. PMR is closely related to giant cell arteritis (GCA), a large-vessel vasculitis that involves the major branches of the aorta, particularly the extracranial branches of carotid artery including temporal arteries. It is currently believed that PMR and GCA may represent different manifestations of the same disease process...

INTRODUCTION: Segmental arterial mediolysis (SAM) is a rare nonatherosclerotic, noninflammatory vasculopathy causing arterial wall necrosis that leads to strictures, dissections, and aneurysms, particularly in medium-sized abdominal arteries. Awareness of SAM is important because, unlike vasculitides, immunosuppressive treatment may worsen the disease process. CASE: A 58-year-old man with multiple medical comorbidities presented with acute epigastric pain and a right incarcerated inguinal hernia that was interpreted as showing bowel strangulation on computed tomography...

Intracranial vessel wall magnetic resonance (MR) imaging has gained much attention in the past decade and has become part of state-of-the-art MR imaging protocols to assist in diagnosing the cause of ischemic stroke. With intracranial vessel wall imaging, vessel wall characteristics have tentatively been described for atherosclerosis, vasculitis, dissections, Moyamoya disease, and aneurysms. With the increasing demand and subsequently increased use of intracranial vessel wall imaging in clinical practice, radiologists should be aware of the choices in imaging parameters and how they affect image quality, the clinical indications, methods of assessment, and limitations in the interpretation of these images...

The prospects for complement-targeted therapy in ANCA-associated vasculitis have been enhanced by a recent clinical trial in which C5a receptor 1 (C5aR1) inhibition safely replaced glucocorticoids in induction treatment. C5aR1 primes neutrophils for activation by anti-neutrophil cytoplasmic antibody (ANCA) and is therefore required in models of glomerulonephritis induced by anti-myeloperoxidase antibody. Although humoral and cellular autoimmunity play essential roles in ANCA-associated vasculitis, a role for C5aR1 in these responses has not been described...

Spontaneous coronary artery dissection (SCAD) is an emerging and rare cause of acute coronary syndrome and sudden cardiac death. While it was previously reported among young females with fibromuscular dysplasia, new literature indicates that this condition could occur in older populations. Polyarteritis nodosa (PAN) causes systemic necrotizing vasculitis which typically affects small to medium-sized muscular arteries and could affect the coronary arteries. A few case reports of PAN causing acute coronary artery disease have been reported in the literature...

Idiopathic carotidynia (IC) is a rare and poorly understood syndrome consisting of unilateral neck pain, tenderness, and increased pulsations over the affected carotid bifurcation. A growing body of evidence supports the hypothesis that IC is a distinct clinicopathologic entity with characteristic imaging features. We report the case of a 34-year-old Caucasian male presenting with intense unilateral neck pain in the emergency setting. Computed tomography and ultrasonography revealed fusiform eccentric thickening of the ipsilateral carotid bifurcation without vessel narrowing...

Over the last decades, the importance of inflammatory processes in pediatric stroke have become increasingly evident. Ischemia launches a cascade of events: activation and inhibition of inflammation by a large network of cytokines, adhesion and small molecules, protease, and chemokines. There are major differences in the neonatal brain compared to adult brain, but developmental trajectories of the process during childhood are not yet well known. In neonatal stroke ischemia is the leading pathophysiology, but infectious and inflammatory processes have a significant input into the course and degree of tissue damage...

BACKGROUND AND PURPOSE: Childhood arteriopathies are rare but heterogenous, and difficult to diagnose and classify, especially by nonexperts. We quantified clinical and imaging characteristics associated with childhood arteriopathy subtypes to facilitate their diagnosis and classification in research and clinical settings. MATERIALS AND METHODS: The Vascular Effects of Infection in Pediatric Stroke (VIPS) study prospectively enrolled 355 children with arterial ischemic stroke (2010-2014)...

The authors have analyzed the causes of ischemic stroke (IS) in more than 600 young patients examined in the cerebrovascular department of the Neurological Research Center (Moscow) during the period 2003-2016 years. It has been suggested that a wider use of high-resolution MRI and T1 weighted db-fs images as well as intracranial CTA will help to verify more often intracranial dissection and primary cerebral vasculitis that will result in a decrease of cryptogenic IS frequency.

BACKGROUND: So-called juvenile stroke, i.e., stroke in a person aged 18 to 55, affects approximately 30 000 persons per year in Germany and is thus an important cause of mortality and permanent morbidity. The spectrum of causes of stroke is broader in this age group than in older patients and is also differently distributed. METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed and on current guideline recommendations...

RATIONALE: Medial medullary infarction accounts for less than 1% of brain infarctions, and medial medullary infarctions is very rarely caused by antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. PATIENT CONCERNS: We report the case of a 76-year-old man at low risk of arteriosclerosis who presented with disorders on the left side including gaze-evoked nystagmus, paralysis of the extremities, pyramidal signs, sensory disturbance, and dysesthesia. Brain magnetic resonance imaging also showed right medial medullary infarction...

BACKGROUND: The etiology of spontaneous dissection of coronary artery (SDCA) is not well understood yet. Different studies have linked this entity to pregnancy, physical stress, collagen diseases and vasculitis. In general, patients do not exhibit the classic risk factors for coronary artery disease, which mandates the suspicion of this condition, especially in young adults with acute coronary syndrome. CASE REPORT: In this article, we report the case of a 63-year old male patient, asymptomatic, who came for periodic evaluation and after evaluation by exercise and myocardial scintigraphy had high suspicion for severe coronary artery disease and underwent coronary angiography, which showed spontaneous dissection of the left and right branches of the coronary arteries...

BACKGROUND: Takayasu arteritis is a rare, chronic large vessel vasculitis involving the aorta and its primary branches. As the disease progresses, the active inflammation of large vessels leads to dilation, narrowing and occlusion of the arteries. Arterial dissection is due to separation of the layers of the arterial wall resulting in a false lumen, where blood seeps into the vessel wall. Neurological sequelae of intracranial arterial dissection results from cerebral ischemia due to thromboembolism and hypo perfusion...

BACKGROUND: Patients with the kyphoscoliotic type of Ehlers-Danlos syndrome have an increased risk of vascular complications such as aortic dissection and perforation. Cerebral ischemia has only rarely been documented. PATIENT DESCRIPTION: This 13-year-old girl with the kyphoscoliotic type of Ehlers-Danlos syndrome experienced a large right middle cerebral artery distribution infarction. Full intravenous heparinization was started in response to presumed arterial dissection...

Segmental arterial mediolysis (SAM) is a rare non-atherosclerotic, non-inflammatory disease of unknown aetiology mostly affecting medium-sized arteries of the splanchnic circulation. Histologically, SAM is characterized by vacuolization and lysis of the arterial media leading to dissection, stenosis/occlusion or aneurysms. Symptoms vary from unspecific abdominal pain to hemorrhagic shock due to vessel rupture. The clinical and radiological presentation can mimic vasculitis, fibromuscular dysplasia or collagen vascular diseases...

BACKGROUND: Horton's disease is a systemic inflammatory vasculitis, usually found in persons over 50years old. It affects medium and large-sized arteries stemming from the external carotid, especially the superficial temporal arteries. It can affect extracranial large vessels but only rarely the aorta. Diagnosis of aortitis is difficult and its incidence is probably underestimated. CASE PRESENTATION: A 68-year-old Caucasian woman consulted in an emergency department for febrile abdominal pain with inflammatory syndrome...

Kawasaki disease (KD) is a pediatric vasculitis with coronary artery aneurysms (CAA) as its main complication. The diagnosis is based on the presence of persistent fever and clinical features including exanthema, lymphadenopathy, conjunctival injection, and changes to the mucosae and extremities. Although the etiology remains unknown, the current consensus is that it is likely caused by an (infectious) trigger initiating an abnormal immune response in genetically predisposed children. Treatment consists of high dose intravenous immunoglobulin (IVIG) and is directed at preventing the development of CAA...
