Thrombosed Aneurysm of the Posterior Inferior Cerebellar Artery and Lateral Medullary Ischemia as the Initial Presentation of Polyarteritis Nodosa: Case Report and Literature Review
A 27-year-old woman with a previously undiagnosed polyarteritis nodosa (PAN) developed lateral medullary stroke related to a thrombosed posterior inferior cerebellar artery (PICA)-origin aneurysm. A concurrent thrombosis of the PICA was identified on high-resolution 3-dimensional CUBE T1 magnetic resonance imaging sequence at 3 T. Body computed tomography angiography, magnetic resonance imaging–magnetic resonance angiography, and digital angiography revealed multiple tiny aneurysms of the visceral arteries and bilateral kidney infarcts.

Carotid Intraplaque Hemorrhage in Patients with Embolic Stroke of Undetermined Source
Many embolic strokes are of undetermined source (ESUS). Carotid artery intraplaque hemorrhage (IPH), an unstable component of atherosclerosis, may be an under-recognized etiology in patients with ESUS. We investigated the prevalence of carotid IPH detected noninvasively by magnetic resonance imaging (MRI).

Positional Brain Single-Photon Emission Computed Tomography Findings in a Case of Limb-Shaking Syndrome
An 84-year-old man, who presented lower limbs limb-shaking syndrome at orthostatism lasting a few seconds, was referred in our stroke unit. Magnetic resonance imaging showed an acute infarction in the right thalamus and the insular cortex, left extracranial carotid stenosis at 80%, and low flow in the right middle cerebral artery but did not explain limb-shaking syndrome symptomatology. We performed comparative positional brain perfusion single-photon emission computed tomography (SPECT), in the upright and in the supine position, to explore and localize hypoperfusion-endangered brain structures that may be involved in the...

Subacute Methotrexate Encephalopathy Mimicking Ischemic Stroke With Dynamic Changes on Magnetic Resonance Imaging
We report a 35-year-old woman who suddenly developed left hemiparesis and dysarthria at 13 days after treatment with intrathecal and intravenous methotrexate for intravascular large B cell lymphoma with possible central nervous system infiltration. Seven hours after onset, she developed further right hemiparesis and aphasia. However, the majority of neurologic symptoms disappeared spontaneously and completely by 34 hours. We also recorded the dynamic progression and regression of abnormal signals in the bilateral corona radiata on diffusion-weighted imaging, in parallel with neurologic symptoms.

The Processing Time for Recanalization and Size of Ischemic Lesions on DWI is Related With Complete Reperfusion After Mechanical Thrombectomy
Recent studies demonstrated that modified thrombolysis in cerebral infarction (TICI) 3 reperfusion have better functional outcomes than modified TICI 2b after mechanical thrombectomy in acute ischemic stroke with large vessel occlusion. The purpose of this study was to determine significant factors to forecast the presence of complete reperfusion after mechanical thrombectomy based on multimodal magnetic resonance imaging (MRI). We investigated 96 consecutive patients with acute large intracranial artery occlusion of anterior circulation who based on multimodal MRI.

Intraplaque Microvascular Flow Signal in Superb Microvascular Imaging and Magnetic Resonance Imaging Carotid Plaque Imaging in Patients with Atheromatous Carotid Artery Stenosis
Carotid artery atherosclerosis is one of the major risk factors for ischemic stroke. Intraplaque neovascularization (IPN) is one of the steps toward the development of vulnerable plaque. Superb microvascular imaging (SMI) is a new ultrasonographic technique for visualizing low-velocity and microvascular flow by clutter suppression to extract flow signals from large to small vessels and enables visualization of intraplaque microvascular flow (IMVF) without echo contrast media. We aimed to investigate the association between IMVF signal in SMI and MRI plaque imaging among patients with atherosclerotic carotid stenosis.

Parity As a Protective Biomarker Against Silent Brain Infarction in Community-Dwelling Older Adults: The Sefuri Study
Background: Although several studies have reported an association between parity and increased risk of stroke, this relationship remains controversial. Aims: The present study aimed to determine whether parity is associated with silent brain infarction (SBI), independent of other confounders. Methods: We analyzed the brain magnetic resonance imaging findings in 576 of community-dwelling older adults with a mean age of 72.1 years. All female participants were asked to provide information regarding the total number of live births, their age at the last parity, and their age at menopause.

Response to Letter to the Editor
We appreciated Sneha et al. ’s comments on our recent article.1 Among the 109 total patients, 25 patients (22.9%) developed symptomatic hemorrhagic infarction (HI) in this study.2 The prevalence of HI in this study was high compared to that of a previous study.3 This difference might be explained by the longer-onset treatmen t timing (24 hours-1 week in this study versus 24-36 hours in the previous study), lower Alberta Stroke Program Early CT-Diffusion-Weighted magnetic resonance Imaging (ASPECT-DWI) score, and higher age, as Sneha et al.

Racial Disparities in Magnetic Resonance Imaging and Perfusion-Diffusion Mismatch
The central concept of mismatch between perfusion and diffusion targets identified by magnetic resonance imaging offers an approximation of the tissue at risk of infarction if reperfusion is not achieved. This measure is becoming increasingly relevant in determining eligibility for and prognosis following thrombolytic and endovascular treatments, particularly at extended time windows. A few studies have shown that Black stroke patients are more likely to suffer small-vessel ischemic strokes and fewer cardioembolic strokes occluding large vessels.

Brachial-Ankle Pulse Wave Velocity is Related to the Total Cerebral Small-Vessel Disease Score in an Apparently Healthy Asymptomatic Population
Cerebral small-vessel disease (CSVD) is an extensive cerebrovascular disease that mainly involves the perforating arterioles, capillaries and venules and plays a crucial role in stroke and dementia.1 Due to the inability of conventional noninvasive angiography to display small cerebral vessels, relevant brain parenchymal lesions on brain magnetic resonance imaging (MRI) can be used as an alternative marker for CSVD. These markers include recent small subcortical infarcts, lacunes of presumed vascular origin, white matter hyperintensity (WMH) of presumed vascular origin, perivascular space (PVS), cerebral microbleeds (CMBs)...
