Intracranial vessel wall magnetic resonance imaging features of infectious vasculitis
Vasculitis is a complication of several infectious diseases affecting the central nervous system, which may result in ischemic and/or hemorrhagic stroke, transient ischemic attack, and aneurysm formation. The infectious agent may directly infect the endothelium, causing vasculitis, or indirectly affect the vessel wall through an immunological mechanism. The clinical manifestations of these complications usually overlap with those of non-infectious vascular diseases, making diagnosis challenging.

Ultrasound Criteria for Diagnosing Spontaneous Cervical Artery Dissections
This article describes the diagnostic criteria and typical findings of spontaneous dissection, in which no dissecting membrane is to be expected as in aortic dissection. Traumatic dissections following blunt or penetrating injuries also present with different findings. Examiners should be aware of possible differential diagnoses whose ultrasound image may mimic a dissection. A frequently occurring but avoidable cause of misdiagnosis is idiopathic carotidynia. Ultrasound also enables differentiation between dissection and vasculitis or carotid web and detection of normal variants such as fenestration of the vertebral artery...

Childhood Cerebral Vasculitis
AbstractCerebral vasculitis is increasingly recognized as a  common cause of pediatric arterial stroke. It can present with focal neurological deficits, psychiatric manifestations, seizures, and encephalopathy. The etiopathogenesis of childhood cerebral vasculitis (CCV) is multifactorial, making an inclusive classification challenging. In this review, we de scribe the common and uncommon CCV with a comprehensive discussion of etiopathogenesis, the role of various imaging modalities, and advanced techniques in diagnosing CCV. We also highlight the implications of relevant clinical, laboratory, and genetic findings to reac...

High-resolution MR vessel wall imaging in determining the stroke aetiology and risk stratification in isolated middle cerebral artery disease
ConclusionHigh-resolution MRVWI can help in identifying the aetiology of stroke. The HRVWI characteristics in ICAD can help in risk stratification.

In vitro and pilot in vivo imaging of 18  kDa translocator protein (TSPO) in inflammatory vascular disease
ConclusionDespite good uptake on surgical samples in vitro, [11C]-PBR28 and [18F]-PBR06 are not viable clinical tools for imaging inflammatory vascular disease.Trial registration: NCT02513589, registered 31 July 2015 and NCT00547976, registered 23 October 2007.https://clinicaltrials.gov.

Endovascular treatment of pediatric ischemic stroke: A single center experience and review of the literature.
We report our single-center experience with thrombectomy of LVO in a series of pediatric patients, and perform a review of the literature. METHODS: Retrospective review of consecutive pediatric thrombectomy cases between 2011 and 2018. Demographic variables, imaging data, technical aspects and clinical outcome were recorded. RESULTS: In a period of 7 years, 7 children were treated for LVO at our center. Median age was 13 (2-17), and median Ped-NIHSS was 15 (3-24), and the median ASPECTS was 8 (2-10). Five patients had cardiac disease, and 2 of them were under external cardiac assistance. Median time from onset of...

COVID-19 Neurologic Complication with CNS Vasculitis-Like Pattern ADULT BRAIN
We report a unique neurologic complication of COVID-19 in a patient who had extensive cerebral small-vessel ischemic lesions resembling cerebral vasculitis in a characteristic combined imaging pattern of ischemia, hemorrhage, and punctuate postcontrast enhancement. Also, a characteristic lower extremity skin rash was present in our patient. Our observation lends support to the increasingly suspected mechanism of "endotheliitis" associated with this novel coronavirus.

Clinical and Imaging Characteristics of Arteriopathy Subtypes in Children with Arterial Ischemic Stroke: Results of the VIPS Study PEDIATRICS
CONCLUSIONS: Childhood arteriopathy subtypes have some typical features that aid diagnosis. Better imaging methods, including vessel wall imaging, are needed for improved classification of focal cerebral arteriopathy of childhood.

Intracranial and Extracranial Neurovascular Manifestations of Takayasu Arteritis ADULT BRAIN
CONCLUSIONS: Intracranial vascular abnormalities in patients with Takayasu arteritis presenting with neurologic symptoms are not rare, with cerebral vasculitis seen in 7.8% of patients, and stroke secondary to large-vessel occlusion, in 3.9% of patients. Cervical vascular manifestations of Takayasu arteritis were present in most patients in our study.

Impact of Implementing Cardiac CT in Evaluating Patients Suspected of Cardioembolic Stroke
Conclusions: Implementing cardiac CT in assessing patients suspected of cardioembolic stroke added value to echocardiographic evaluation, by detecting major embolic potential findings. In addition, cardiac CT revealed additional potentially significant stroke-unrelated findings and CAD.
