High-resolution Magnetic Resonance Imaging of Symptomatic Middle Cerebral Artery Dissection
Dissection of the middle cerebral artery (MCA) is less frequent compared with dissection of vessels in the vertebrobasilar system or dissection of the carotid artery. High-resolution cross-sectional magnetic resonance imaging (HRMRI) has emerged as a potential technique for atherosclerotic plaque imaging in MCA. We enrolled 3 patients with MCA dissection on whom HRMRI was performed for evaluation of MCA stenosis. Two patients had an embolic infarction in the MCA territory and focal dissection. One patient had a massive infarction in the MCA territory and long-segment dissection of the MCA. On HRMRI, our objectives had an i...

A Case of Sinus Arrest and Post-hiccup Cough Syncope in Medullary Infarction
We describe asymptomatic sinus arrest and post-hiccup cough syncope in a patient with medullary infarction. A 78-year-old woman developed arrhythmia, hiccup, and cough syncope attacks. Neurological examination was not remarkable. Cough syncope occurs after hiccup attacks. Bradycardia and decreased blood pressure were also present after the beginning cough. Holter 24-hour electrocardiography monitor exhibited 65 episodes of asymptomatic sinus arrest more than 3 seconds. Magnetic resonance imaging disclosed acute infarction in the bilateral medial regions and the right tegmentum of the upper and middle medulla oblongata. Ce...

Postoperative Dural Arteriovenous Fistula in a Patient with Cowden Disease: A Case Report
We report the case of a 37-year-old male with Cowden disease that caused a gradual neurological deficit because of rupture of a brain stem cavernous hemangioma. Removal of the hemangioma and hematoma was performed with an infrafacial triangle approach. Nine months after the operation, magnetic resonance imaging showed abnormal vessels on the cerebellar surface. Digital subtraction angiography showed a dural arteriovenous fistula (dAVF) from part of the meningeal artery to the ectatic inferior vermian vein with cortical reflux. After embolization, surgical obliteration of the dAVF was performed. Surgical findings showed ne...

A New Classification System for Ischemia Using a Combination of Deep and Periventricular White Matter Hyperintensities
In this study, we aimed to evaluate the validity of the CREDOS ischemia classification system. A total of 352 patients with cognitive impairments were included. Their WMH scores were rated using the CREDOS WMH visual rating scale. These patients were divided into 3 groups according to the CREDOS ischemia classification system. The volume of WMH was also automatically measured. The number of lacunes and microbleeds (MBs) were counted. The CREDOS ischemia classification system was revised with factor analysis using vascular risk factors and cerebrovascular disease (CVD) markers (WMH volume, lacunes, and MBs). External valida...

A Dilated Surface Appearance on Basiparallel Anatomic Scanning–Magnetic Resonance Imaging Is a Useful Tool for the Diagnosis of Spontaneous Vertebral Artery Dissection in Lateral Medullary Infarction
Spontaneous dissection of the vertebral artery (VA) is a major vascular lesion causing lateral medullary infarction (LMI). A dilated surface appearance of the VA is a feature of VA dissection and can be observed on basiparallel anatomic scanning (BPAS)–magnetic resonance imaging (MRI). The aim of this study was to validate BPAS-MRI in the diagnosis of VA dissection in patients with LMI. The subjects of the present study were 41 consecutive patients with LMI within 7 days of onset. The diagnosis of VA dissection was made with the clinical criteria-based diagnosis. Percent (%) dilatation of the VA on BPAS-MRI was calculat...

Early Menopause and the Risk of Silent Brain Infarction in Community-Dwelling Elderly Subjects: The Sefuri Brain MRI Study
Our previous study showed that the male predominance of silent brain infarction (SBI) was largely because of higher prevalence of alcohol habit and smoking in men than in women. In the present study, we further conducted an analysis of brain magnetic resonance imaging findings to examine whether early menopause contributes to SBI in community-dwelling subjects. Women were queried as to the age and cause of menopause, the total number of children, and the age at giving birth to her last child. Among 306 female subjects aged 60 years or older, univariate analysis showed that early menopause (total or natural) was significan...

Loading Dose of Clopidogrel in Combination with Other Antithrombotic Therapy for Capsular Warning Syndrome
A 66-year-old man had repeated stereotypical transient ischemic attacks (TIAs) of dysarthria and left hemiparesis. His symptoms were considered capsular warning syndrome (CWS), for which the responsible lesion was found on magnetic resonance imaging to be in the right putamen expanding to the corona radiata. Although administration of antithrombotic therapy including aspirin was ineffective, no further TIAs occurred after a loading dose of clopidogrel was added. A loading dose of clopidogrel combined with other antithrombotic therapy might be an effective treatment for CWS.

In Vitro and In Vivo Evaluation of a Magnetic Resonance Imaging–guided Focused Ultrasound System for Dissolving Clots in Combination with Thrombolytic Drugs
Conclusions: The MRgFUS technique was proven successful in dissolving clots in vitro and in vivo. It was found that the volume of dissolved clot increases with acoustic intensity and beam size and decreases with frequency. With this system, it was possible to push ultrasound through a plastic phantom skull using a .5 MHz transducer. The beam of ultrasound through the phantom skull was monitored using the MRI technique of fast spoiled gradient. Finally, the thrombus in the in vivo model (ear artery) was successfully destroyed with the therapeutic protocols investigated in the in vitro models. This study shows that FUS ...
