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.

Ischaemic stroke as the first presentation of antineutrophilic cytoplasmic autoantibody ‐associated vasculitis
We present the case of a 71-year-old woman with positive myeloperoxidase antineutrophil cytoplasmic antibodies and negative proteinase 3 autoantibodies. The patient presented with 1  week history of pyramidal weakness in both upper and lower limbs, hyperreflexia, and clonus. Magnetic resonance imaging of the brain demonstrated widespread bihemispheric cortical and deep white matter acute infarcts, which are consistent with features of stroke secondary to vasculitis. Myelopero xidase antineutrophilic cytoplasmic autoantibody-positive vasculitis diseases are more commonly associated with renal, pulmonary, and cutaneous man...

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...

Immunoglobulin G4-Related Disease Presenting as Temporal Bone Lesion with Facial Nerve Palsy
We report a case of IgG4-RD with infiltration of the temporal bone and surrounding structures in a patient with systemic vasculitis on systemic steroids. A 31-year-old woman presented with right-sided facial weakness, headache, and right ear hearing loss. On examination, redness and retraction of the right tympanic membrane and facial paresis (House-Brackman IV) were noted. Computed tomography imaging showed mastoiditis, temporal lobe stroke, and brain abscess. Magnetic resonance imaging (MRI) showed infiltration in the infratemporal fossa, nasopharynx, spreading along the Eustachian tube and perineurally along the branche...

COVID-19 Infection and Recurrent Stroke in Young Patients With Protein S Deficiency: A Case Report
Conclusions: SARS-CoV-2 infection potentializes the prothrombotic effect and vascular inflammation by accentuating protein S deficit. The place of steroids seems justifiable in the presence of symptoms of vasculitis in brain imaging.

A brief report on incidence, radiographic feature and prognostic significance of brain MRI changes after anti-PD-1/PD-L1 therapy in advanced non-small cell lung cancer
ConclusionsBrain MRI aberrations developed after ICI treatment are not uncommon, and their manifestations vary a lot. Patients developing brain MRI aberrations tended to have better prognosis, which needed to be further investigated.

Herpes simplex virus 2 vasculitis as cause of ischemic stroke in a young immunocompromised patient
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...

Diagnostic value of HR ‐MRI and DCE‐MRI in unilateral middle cerebral artery inflammatory stenosis
ConclusionHR ‐MRI is an accurate direct imaging method and has a high value for the etiological diagnosis of central nervous system vasculitis. DCE‐MRI could be an effective way to evaluate and monitor blood–brain barrier to prevent clinical ischemic stroke.

Q Fever, CNS Vasculitis, and Stroke: A Case Report
A 43-year-old male pet shop owner on leflunomide for seronegative rheumatoid arthritis presented locally with strange behavior and aphasia, preceded by flu-like symptoms and high fevers. Initial workup revealed cerebrospinal fluid lymphocytic pleocytosis (22 cells, 74% lymphocytes), for which he was started on empiric antimicrobial therapy. Magnetic resonance imaging of the brain revealed extensive, bilateral ischemic strokes (Figure). A transesophageal echocardiogram was negative. He was then transferred to our institution for further evaluation.

Disseminated cutaneous herpes zoster and multiple cerebral infarcts in an adult with diabetes mellitus
We present the case of a patient with a medical history of type 2 diabetes mellitus (DM) who experienced disseminated cutaneous VZV infection followed by multiple cerebral infarcts associated with VZV vasculopathy. Brain magnetic resonance imaging revealed multiple hyperintense lesions over the bilateral deep white matter and basal ganglia. A skin biopsy revealed small-vessel leukocytoclastic vasculitis with neutrophilic, lymphocytic, and eosinophilic infiltration. This case report describes the rare finding of cutaneous leukocytoclastic vasculitis in VZV infection and highlights that VZV infection is an uncommon but criti...

Behcet's Disease With Cerebral Artery Infarction Caused by Cerebral Arteritis as an Early Symptom Only With Elevated Interleukin-8
Conclusion: This case demonstrates that neurological involvement might be an early symptom of BD. IL-8 could act as a novel target for the treatment of BD theoretically and probably play a key role in disease recovery.

Combined brain/heart magnetic resonance imaging in systemic lupus erythematosus.
Authors: Mavrogeni S, Koutsogeorgopoulou L, Dimitroulas T, Markousis-Mavrogenis G, Boki K, Katsifis G, Vartela V, Kallenberg CG, Kolovou G, Kitas G Abstract Cardiovascular disease (CVD) in systemic lupus erythematosus (SLE) and neuropsychiatric SLE (NPSLE) have an estimated prevalence of 50% and 40% respectively and both constitute major causes death among SLE patients. In this review, we propose a combined brain/heart magnetic resonance imaging (MRI) for SLE risk stratification. The pathophysiologic background of NPSLE includes microangiopathy, macroscopic infarcts and accelerated atherosclerosis. Classic brain MR...

A case of acute encephalophathy with residual neurological sequelae induced by immunoglobulin A vasculitis
In conclusion, acute encephalopathy with IgAV could cause neurological sequelae by prolonged seizure, and elevated IL-6 in CSF and laterality of cerebral blood flow in ASL might be useful to predict the prognosis of CNS dysfunction of IgAV.
