Primary varicella zoster virus (VZV) infection, predominantly in the pediatric population, presents with pyrexia and a classic pruritic vesicular rash. In adults, although less common, it is more severe and linked to more complications. Neurological complications, which account for less than 1% of all VZV complications, include meningitis, encephalitis, arterial vasculopathy, and venous thrombosis. We present a case of a 39-year-old male who developed extensive cerebral venous sinus thrombosis following primary VZV infection...

The importance of the posterior cerebral artery (PCA) involvement in moyamoya disease has been highlighted in recent years. However, few studies compared the impact of PCA lesions in moyamoya disease between pediatric and adult patients. We conducted this study to summarize the clinical features of moyamoya patients with PCA lesions and describe the difference between pediatric and adult patients. We reviewed the records of 696 consecutive moyamoya vasculopathy patients from 2009 to 2015. The Suzuki and the Miyamoto stages were used to evaluate the steno-occlusive lesions of the anterior and posterior arteries...

BACKGROUND AND PURPOSE: The effects of lytic stroke therapy in patients with sickle cell anemia are unknown, although a recent study suggested that coexistent sickle cell anemia does not increase the risk of cerebral hemorrhage. This finding calls for systemic analysis of the effects of thrombolytic stroke therapy, first in humanized sickle mice, and then in patients. There is also a need for additional predictive markers of sickle cell anemia-associated vasculopathy. METHODS: We used Doppler ultrasound to examine the carotid artery of Townes sickle mice tested their responses to repetitive mild hypoxia-ischemia- and transient hypoxia-ischemia-induced stroke at 3 or 6 months of age, respectively...

BACKGROUND AND PURPOSE-: Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a monogenic small vessel disease, caused by C-terminal truncating TREX1 mutations, that can be considered a model for stroke and vascular dementia. The pathophysiology of RVCL-S is largely unknown, but systemic endothelial involvement has been suggested, leading to pathology in the brain and other highly vascularized organs. Here, we investigated circulating endothelial markers to confirm endothelial involvement and identify biomarkers for disease activity...

Migraines are generally considered a relatively benign neurological condition. However, research has shown an association between migraines and stroke, and especially between migraine with aura and ischaemic stroke. Patients can also suffer from migrainous infarction, a subset of ischaemic stroke that often occurs in the posterior circulation of younger women. The exact pathogenesis of migrainous infarct is not known, but it is theorised that the duration and local neuronal energy level from cortical spreading depression may be a key factor...

Radiotherapy is one of the standard treatments for medulloblastoma. However, therapeutic central nervous system irradiation in children may carry delayed side effects, such as radiation-induced tumor and vasculopathy. Here, we report the first case of coexisting meningioma and moyamoya syndrome, presenting 10 years after radiotherapy for medulloblastoma. A 13-year-old boy presented with an enhancing mass at the cerebral falx on magnetic resonance imaging (MRI) after surgery, radiotherapy (30.6 Gy craniospinal axis, 19...

BACKGROUND: Magnetic resonance imaging-visible perivascular spaces (PVS) are related to interstitial fluid clearance pathways (including amyloid-β) in the brain and are suggested to be a marker of cerebral small vessel disease. We investigated the role, topography, and possible implications of PVS in cognitive impairment. METHODS AND RESULTS: A total of 1504 patients undergoing memory clinic investigation and an associated brain magnetic resonance imaging scan were included in this cross-sectional study...

Stroke is a dramatic complication of sickle cell disease (SCD), which is associated with cerebral vasculopathies including moya moya, intravascular thrombi, cerebral hyperemia, and increased vessel tortuosity. The spontaneous occurrence of these pathologies in the sickle cell mouse model has not been described. Here, we studied Townes humanized sickle cell and age-matched control mice that were 13 months old. We used in vivo two-photon microscopy to assess blood flow dynamics, vascular topology, and evidence of cerebral vasculopathy...

Moyamoya vasculopathy (MMV) is a stenoocclusive cerebrovascular disease frequently affecting adolescent females. Thus, the management of pregnancy is of major interest for physicians dealing with MMV patients. However, clinical data concerning pregnant MMV patients is lacking. Our aim was to analyze the course of pregnancy in our European MMV patient cohort. We retrospectively identified MMV patients with a history of pregnancy who were treated in our institution. We analyzed demographic data, clinical symptoms, treatment, and detailed history of pregnancies...

Intracranial Arterial Aneurysms (IAAs) are relatively rare in paediatric population and they account for at least 10%-15% of haemorrhagic strokes which occur during the first two decades of life. Here we present a unique and unusual case of Human Immunodeficiency Virus (HIV) infected child who presented with intracranial aneurysms with formation of collaterals and vasculopathy, demonstrating low viral count despite receiving adequate antiretroviral treatment. Intracranial vascular involvement, their complications and its incidence in these patients may become increasingly common as the management of human immunodeficiency virus infection continues to improve and afflicted patients survive for longer periods because of advancement in the antiretroviral treatment...

Pompe disease is an autosomal recessive disorder in which deficiency of the lysosomal enzyme acid alpha-glucosidase results in the accumulation of glycogen mostly in muscle tissues. Several reports suggest a higher incidence of intracranial vascular abnormalities (IVAs) in this condition, as well as brain microbleeds and cerebral vasculopathy. The aim of our study was to evaluate through neuroimaging studies the incidence of these anomalies in our cohort of late-onset Pompe disease (LOPD) patients asymptomatic for cerebrovascular disease, looking for correlations with clinical and genetic data...

BACKGROUND: Children with sickle cell anemia (SCA) have an 11% risk of stroke by the age of 18. Chronic transfusion applied in patients detected to be at risk by transcranial Doppler allows a significant reduction of stroke risk. However, chronic transfusion exposes to several adverse events, including alloimmunization and iron overload, and is not curative. Hematopoietic stem cell transplantation allows termination of the transfusion program, but its benefit has not been demonstrated...
