Painless Hypoglossal Palsy as an Isolated Symptom of Spontaneous Carotid Dissection
We report a case of a 49-year old woman with a left sICAD presenting with isolated ipsilateral hypoglossal palsy as the sole clinical sign. Compared to other cases, local pain was absent and other cranial nerves were not affected. Further, sICAD could not be detected in repeated Doppler-/Duplex-sonography, but magnetic resonance imaging and MR-angiography only.

A Simple Score (AVFS) to Identify Spinal Dural Arteriovenous Fistula before Spinal Digital Subtraction Angiography
Background: Spinal dural arteriovenous fistula (SDAVF) is a rare disorder with the presenting of nonspecific clinical symptoms and signs at onset, which can be a challenge to diagnose promptly and leads to the overusing of spinal digital subtraction angiography (SpDSA) in clinical practice. The purpose of this study was to find specific characteristics of SDAVF by comparing the clinical and radiologic data between the SpDSA-identified patients with SDAVF and SpDSA-negative patients, who were suspected with spinal vascular diseases before admission.Methods: From 2006 to 2011, patients presented to Huashan hospital with spin...

Magnetic Resonance Imaging Versus Computed Tomography for Identification and Quantification of Intraventricular Hemorrhage
Conclusions: MRI identifies small volumes of IVH in cases not detected by CT and yields higher estimates of intraventricular blood volume. These data indicate that consideration of technical differences is needed when comparing images from the 2 modalities in the evaluation for IVH.

Eight-and-a-Half Syndrome: A Rare Presentation of Pontine Infarction
We report a case of a 65-year-old man who presented with eight-and-a-half syndrome in which brain magnetic resonance imaging scan revealed a lacunar pontine infarction.

Efficacy of Extracranial–Intracranial Bypass for Progressive Middle Cerebral Artery Occlusion Associated with Active Sjögren's Syndrome: Case Report
Sjögren syndrome affecting the major cerebral arteries is rare, and an optimal therapeutic strategy to counteract such a lesion has not yet been established. We herein report a case of a 39-year-old woman with a history of primary Sjögren syndrome, which had previously been treated with immunosuppressive therapy, manifesting with a crescendo transient ischemic attack because of left middle cerebral artery stenosis. Despite the administration of high doses of prednisolone and azathioprine for active Sjögren syndrome, the frequency of crescendo transient ischemic attacks increased with the progression of stenosis and magn...

Isolated Unilateral Hypoglossal Nerve Paralysis Caused by Internal Carotid Artery Dissection
We here report the case of isolated hypoglossal nerve paralysis. Magnetic resonance imaging demonstrated characteristic findings of internal carotid artery dissection that should be considered as one of the differential diagnosis of ipsilateral pure hypoglossal nerve paralysis.

Association between Microbleeds Observed on T2*-weighted Magnetic Resonance Images and Dysphagia in Patients with Acute Supratentorial Cerebral Hemorrhage
Conclusions: In addition to assessing just the presence or absence of CMBs, clinicians should identify the presence of bilateral or deep lesions in patients with ICH from the perspective of swallowing dysfunction.

The “Heart Appearance” Sign in Bilateral Pontine Infarction
Although rarely seen, bilateral anteromedial infarction of the pons demonstrates the characteristic “heart appearance” sign on magnetic resonance imaging (MRI). This sign has hitherto been described in only 2 patients before this article. This typical pattern can be attributed to atherosclerotic or thrombotic involvement of bilateral paramedian and short circumferential pontine arteries supplying the anteromedial pons.

Collateral Flow and Brain Changes on Computed Tomography Angiography Predict Infarct Volume on Early Diffusion-weighted Imaging
We investigated whether a computed tomography (CT)–based score could predict a large infarct (≥80 mL) on early diffusion-weighted magnetic resonance imaging (DWI).

Risk Factors of Cerebral Microbleeds in Strictly Deep or Lobar Brain Regions Differed
T2*-weighted gradient echo magnetic resonance imaging is sensitive in detecting cerebral microbleeds (MBs), but there are few reports on the risk factors of MBs in different brain regions. Therefore, we aimed to investigate whether the risk factors associated with the presence of MBs in strictly deep or lobar brain regions were different.

Transcranial Color Flow Imaging Can Evaluate the Severity of Periventricular Hyperintensity
The goal of this study was to investigate the relationship between white matter lesions on magnetic resonance imaging and flow parameters in the middle cerebral artery (MCA) measured by transcranial color flow imaging.

Clinical Associations of Cerebral Microbleeds on Magnetic Resonance Neuroimaging
Susceptibility-weighted and gradient-recalled echo T2* magnetic resonance imaging have enabled the detection of very small foci of blood within the brain, which have been termed “cerebral microbleeds.” These petechial intraparenchymal hemorrhages have begun to emerge as diagnostically and prognostically useful markers in a variety of disease states. Severe hypertension and cerebral amyloid angiopathy are perhaps the best established microhemorrhagic conditions from neuroimaging literature; however, many others are also recognized including cerebral autosomal dominant arteriopathy, subcortical infarcts, and leukoencepha...

Usefulness of Laser Speckle Flowgraphy for the Assessment of Ocular Blood Flow in Extracranial–Intracranial Bypass
Laser speckle flowgraphy (LSFG) is a noninvasive technique that can measure relative blood flow velocity in the optic fundus. The authors present a case of symptomatic internal carotid artery occlusion treated with superficial temporal artery (STA)–middle cerebral artery (MCA) bypass in which an improvement of ocular circulation was confirmed by LSFG. A 47-year-old man presented with a 1-month history of repeated left blurred vision and motor weakness of the right leg. Diffusion-weighted magnetic resonance imaging revealed a small infarction in the left frontal lobe.

Unilateral Symptomatic Intracranial Arterial Stenosis and Myopathy in an Adolescent with Graves Disease: A Case Report of an High-resolution Magnetic Resonance Imaging Study
Vascular and muscular involvements in Graves disease (GD) are rare. Here, we report a case of a 17-year-old patient with unilateral symptomatic middle cerebral artery stenosis concurrent with GD and myopathy. He presented with a 1-day history of acute severe right-sided hemiparesis and aphasia and a 3-week history of high metabolic syndrome. The pathogenesis of the stenosis is most likely vasculitis rather than atherosclerosis, based on contrast-enhanced high-resolution magnetic resonance imaging showing concentric wall enhancement.
