INTRODUCTION: Spontaneous recanalization of an occluded internal carotid artery (ICA) is thought to be unlikely. However, there has been a growing number of reports describing this phenomenon. Despite this, the frequency, time course, and mechanism of spontaneous recanalization remain unknown. In this paper, we describe a patient with a symptomatic recanalization of an occluded left ICA. CASE REPORT: A 70-year-old woman presented with transient speech arrest and right upper extremity weakness related to an occluded ICA...

BACKGROUND: Both extrinsic (trauma or violent movement) and intrinsic (structural abnormality, atherosclerosis, or hemodynamic instability) factors may result in arterial dissection. The role of these factors in the origin or progression of dissection remains unclear. This study aimed to characterize the clinical features, radiologic features, and outcomes of intracranial vertebral artery dissection compared with carotid artery dissection and to determine the major causative factors. METHODS: Consecutive patients with craniocervical dissection (n=127) were retrospectively analyzed...

BACKGROUND: Subclinical paroxysmal atrial fibrillation (AF) is one of the main occult causative mechanisms of embolic stroke of undetermined source (ESUS). Aim of this study was to identify AF predictors, and to develop a score to predict the probability of AF detection in ESUS. METHODS: We retrospectively analyzed ESUS patients undergoing 2-week external electrocardiographic monitoring. Patients with and without AF detection were compared. On the basis of multivariate analysis, predictors of AF were identified and used to develop a predictive score, which was then compared with other existing literature scores...

INTRODUCTION: Permanent perioperative vision loss is caused by ischemic optic neuropathy (ION) or central retinal artery occlusion (CRAO). Whereas diffusion restriction of the optic nerve (ON) on brain magnetic resonance imaging has been previously reported in perioperative posterior ION (PION), there are no reports of ON diffusion restriction in patients diagnosed with acute perioperative CRAO. We present a case of perioperative CRAO to highlight this neuroimaging finding for neuroradiologists and neurologists...

INTRODUCTION: Cerebral vasculitides are often devastating conditions that require immediate diagnosis and treatment. CASE REPORT: We report a pathologically proven clinical case of primary central nervous system vasculitis in a 50-year-old man with a diagnosis of relapsing-remitting multiple sclerosis after alemtuzumab therapy, which required additional immunosuppression to control this life-threatening condition. CONCLUSION: In patients presenting subacute neurological deterioration after alemtuzumab therapy, primary central nervous system vasculitis should be considered as a differential diagnosis among other autoimmune conditions...

BACKGROUND: Migraine is associated with neuroimaging differences in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). However, it is unknown if migraine-related disability (MRD) or if calcitonin gene-related peptide (CGRP), a vasoactive peptide important in migraine pathology, have radiographic implications. The aims of this study were to identify whether MRD or interictal serum CGRP levels impacted neuroimaging findings for those with CADASIL...

INTRODUCTION: Dural arteriovenous fistula (DAVF) is a vascular malformation. Although rare, DAVFs can represent a potentially reversible cause of dementia. Bilateral white matter changes can be detected on the magnetic resonance imaging of patients with DAVFs. Familiarity with symptoms of DAVFs can reduce the incidence of misdiagnosis of dementia syndrome. This study aimed to explore the clinical manifestation, imaging characteristics, and prognosis of dementia with bilateral white matter changes caused by DAVFs...

BACKGROUND: Patients with cerebellar ischemic stroke may be misdiagnosed and may exhibit a delayed time to acute stroke treatment compared with patients with anterior circulation ischemic stroke. The posterior circulation Alberta stroke program early computed tomography score (pc-ASPECT) score has been used to evaluate hyperacute stroke, much as the ASPECT in anterior circulation stroke recently. Our main objective was to evaluate the associations of the clinical and etiological characteristics of ischemic cerebellar infarction patients on admission with their pc-ASPECT scores, as well as the correlations of the pc-ASPECT score with morbidity and mortality rates...
