A Case of Hypertensive Encephalopathy with Enlarged Optic Nerve Sheath Measured by Transorbital Sonography
This case report describes our experience in using transorbital sonography to evaluate pathological changes in the central nervous system in hypertensive encephalopathy. A 49-year-old man with nausea, headache, and mild confusion was diagnosed with hypertensive encephalopathy by brain magnetic resonance imaging (MRI), which revealed vasogenic edema in the bilateral thalamus and the brain stem. Lumbar puncture showed no severe intracranial hypertension. Transorbital sonography showed an increase in the optic nerve sheath diameter (ONSD).

T1-Weighted Magnetic Resonance Carotid Plaque Imaging: a Comparison between Conventional and Fast Spin-Echo Techniques
Magnetic resonance imaging is widely used to evaluate the intraplaque components of the cervical carotid artery. The non –gated T1-weighted spin-echo (SE) technique has been reported to have an excellent ability for discriminating stable and unstable plaques. However, the diagnostic performance of various SE-based techniques remains unclear. Hence, we compared plaque signals obtained by 3 kinds of SE-based methods w ith histological findings.

A Case of Transient Global Amnesia with Small Left Putamen Infarction
A 67-year-old right-handed woman experienced a sudden anterograde and retrograde short-term memory deficit that recovered on the next day. Magnetic resonance imaging (MRI) showed a spotty high-intensity lesion in the left putamen in the diffusion-weighted and fluid-attenuated inversion recovery images. Transient global amnesia due to lacunar infarction of the left putamen was diagnosed. Transient global amnesia is characterized by a sudden onset of anterograde amnesia that disappears within 24 hours.

Assessment of Carotid Plaque Inflammation in Diabetic and Nondiabetic Patients —An Exploratory Ultrasmall Superparamagnetic Iron Oxide-Enhanced Magnetic Resonance Imaging Study
Ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance (MR) imaging enables the identification of inflammation within the atheroma, predominantly by USPIO uptake by macrophages present in atherosclerotic tissue. Diabetic patients, however, may have dysfunctional macrophage activity, which may affect utilization of USPIO in identifying plaque inflammation in this patient cohort.

Venous Infarcts Mimicking Large Vessel Arterial Disease: Watershed Lesions in Deep Cerebral Venous Thrombosis
We read with interest the recent report by Washida et al on multiple deep white matter hyperintensities seen in diffusion-weighted imaging (DWI) in a patient with straight sinus thrombosis.1 We would like to report a similar instance of a 30-year-old female who presented to us with a 4-day history of headache, vomiting, and progressive drowsiness; on examination, she was drowsy and had left hemiparesis. Her initial magnetic resonance imaging demonstrated thalamic and basal ganglia signal changes and bilateral centrum semiovale punctate infarcts (Fig 1, A,B) that suggested possible deep cerebral venous sinus thrombosis a...

Cerebral Venous Sinus Thrombosis Presenting Feature of Systemic Lupus Erythematosus
CVST (cerebral venous sinus thrombosis) may sometimes be associated with autoimmune disorders that require specific treatment. The clinical and magnetic resonance imaging (MRI) findings of systemic lupus erythematosus (SLE) patients with CVST are presented and contrasted with CVST without SLE.

Diagnostic and Prognostic Relevance of Magnetic Resonance Imaging and Electrophysiological Findings in Acute Spinal Ischemia
Our purpose was to classify the rare entity of spontaneous spinal ischemia with clinical, magnetic resonance-tomographic, and electrophysiological parameters to determine criteria for outcome prediction.

Characterizing Deep White Matter Hyperintensities in Patients with Symptomatic Isolated Cortical Superficial Siderosis
In patient with cerebral amyloid angiopathy (CAA) presenting with lobar hemorrhage (LH), magnetic resonance imaging (MRI) white matter hyperintensities (WMH) tend to be predominant in posterior regions with the “multiple subcortical spots” WMH pattern as the most frequent topographical WMH pattern. Our aim was to analyze WMH severity and topographical distribution in patients with cortical superficial siderosis (CSS).

Isolated Medial Rectus Palsy: Rare Presentation of Mesencephalon Infarction
Isolated medial rectus palsy due to mesencephalon lesion is extremely rare. We here describe a patient of midbrain infarction involving the medial rectus subnuclei presenting as isolated medial rectus palsy. Axial diffusion-weighted and coronal T2-weighted magnetic resonance imaging showed acute ischemic lesion in mesencephalon.

High-Resolution Magnetic Resonance Imaging Evidence for Intracranial Vessel Wall Inflammation Following Endovascular Thrombectomy
Intracranial high-resolution vessel wall magnetic resonance imaging evidence of vessel wall inflammation is present following stent retriever manipulation but absent following aspiration thrombectomy. This is presented in a case of rotatory vertebral artery compression causing multiple posterior circulation infarctions requiring multiple separate aspiration and stent retriever thrombectomies.

N ε-(carboxymethyl)lysine Concentration in Debris from Carotid Artery Stenting Correlates Independently with Signal Intensity on T1-Weighted Black-Blood Magnetic Resonance Images
We examined the correlation between N ε-(carboxymethyl)lysine (CML), a main chemical structure of advanced glycation end-products, and the vulnerability of plaques visualized on MRI scans.

Perfusion-weighted MRI parameters for prediction of early progressive infarction in middle cerebral artery occlusion
【Objective】Early progressive infarction (EPI) is frequently observed and related to poor functional outcome in patients with middle cerebral artery (MCA) infarction caused by MCA occlusion. We evaluated the perfusion parameters of magnetic resonance imaging (MRI) as a predictor of EPI.

Proximal Bright Vessel Sign on Arterial Spin Labeling Magnetic Resonance Imaging in Acute Cardioembolic Cerebral Infarction
The congestion of spin-labeled blood at large-vessel occlusion can present as hyperintense signals on perfusion magnetic resonance imaging with 3-dimensional pseudo-continuous arterial spin labeling (proximal bright vessel sign). The purpose of this study was to clarify the difference between proximal bright vessel sign and susceptibility vessel sign in acute cardioembolic cerebral infarction.

Cortical Microinfarcts in Patients with Middle Cerebral Artery Stenosis
Cortical microinfarcts (CMIs) have been correlated to cognitive decline and dementia. It was previously considered only visible on microscope, but was recently reported to be visible on 3.0 Tesla magnetic resonance imaging (MRI) and linked to presence of intracranial stenosis. We aimed to investigate CMIs on 3.0 Tesla MRI in patients with M1 middle cerebral artery (MCA-M1) stenosis.

Isolated Hypoglossal Paralysis Caused by Ischemic Infarction in the Centrum Semiovale
In the present report, we discuss the case of a 66-year-old woman with isolated unilateral hypoglossal paralysis due to cerebral infarction in the centrum semiovale. To date, it has hardly been discussed where the corticolingual tract passes through in the centrum semiovale. Brain magnetic resonance imaging revealed a small ischemic infarction in the contralateral centrum semiovale. We could demonstrate a route of the corticolingual tract.
