Fulminant Cerebral Infarction of Anterior and Posterior Cerebral Circulation after Ascending Type of Facial Necrotizing Fasciitis
Necrotizing fasciitis is a soft tissue infection that is characterized by extensive necrosis of the subcutaneous fat, neurovascular structures, and fascia. Cerebral infarction after facial necrotizing fasciitis has been rarely reported. A 61-year-old woman with diabetes was admitted with painful swelling of her right cheek. One day later, she was stuporous and quadriplegic. A computed tomographic scan of her face revealed right facial infection in the periorbital soft tissue, parotid, buccal muscle, and maxillary sinusitis. A computed tomographic scan of the brain revealed cerebral infarction in the right hemisphere, left ...

Cerebral Infarction in Both Carotid and Vertebrobasilar Territories Associated with a Persistent Primitive Hypoglossal Artery with Severe Dilated Cardiomyopathy
A persistent primitive hypoglossal artery (PPHA) is a relatively rare vascular anomaly of a persistent carotid–basilar anastomosis. A 76-year-old man with severe dilated cardiomyopathy suddenly lost consciousness. A magnetic resonance imaging scan of his brain revealed extensive infarction in the carotid and vertebrobasilar territories. Magnetic resonance angiography revealed a PPHA and occlusion of the left internal carotid artery and vertebrobasilar artery. Cardioembolic infarction associated with a PPHA should be recognized as a possible cause of multiple infarctions in both the carotid and vertebrobasilar distributio...

Cerebral Blood Flow and Oxygen Metabolism Measurements Using Positron Emission Tomography on the First Day after Carotid Artery Stenting
Conclusions: CAS increases cerebral perfusion and improves hemodynamic compromise in patients with symptomatic ICA stenosis. Although we could not clarify the usefulness of PET before and on the first day after CAS in predicting HPS, a high preoperative OEF is related to postoperative marked CBF increase and might be used as a predictor of HPS. Patients with greater hemodynamic compromise with a high preoperative OEF should be managed carefully to prevent HPS, but they have a greater chance of CBF increase after CAS.

Combined Treatment of Methylprednisolone Pulse and Memantine Hydrochloride Prompts Recovery from Neurological Dysfunction and Cerebral Hypoperfusion in Carbon Monoxide Poisoning: A Case Report
A 49-year-old healthy man developed sudden unconsciousness under inadequate ventilation. Blood gas analysis showed carboxyhemoglobin of 7.3%. After normobaric oxygen therapy, he recovered completely 7 days later. At 3 weeks after carbon monoxide (CO) exposures, memory and gait disturbances appeared. Neurological examination revealed Mini-Mental State Examination (MMSE) score of 5 of 30 points, leg hyper-reflexia with Babinski signs, and Parkinsonism. Brain fluid-attenuated inversion recovery imaging disclosed symmetric hypointense lesions in the thalamus and the globus pallidus, and hyperintense lesions in the cerebral w...

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...

Blood Viscosity in Subcortical Vascular Mild Cognitive Impairment with versus without Cerebral Amyloid Burden
Conclusions: Increased DBV is an important contributor to the development of “pure” svMCI (ie, without cerebral amyloid deposition). The relationship between BV and PiB(+) svMCI differed according to ApoE genotype, suggesting that the pathogenesis of PiB(+) svMCI might also be heterogeneous.

Noninvasive Evaluation of Collateral Blood Flow through Circle of Willis in Cervical Carotid Stenosis Using Selective Magnetic Resonance Angiography
Conclusions: Selective MRA techniques can readily suppress signals from the distal blood flow of the target artery and visualize the presence of collateral flows through the circle of Willis in patients with cervical ICA stenosis.

Microvasculature of Carotid Atheromatous Plaques: Hemorrhagic Plaques Have Dense Microvessels with Fenestrations to the Arterial Lumen
Background: Microvessels in atheromatous plaques are well known to play a role in plaque vulnerability associated with intraplaque hemorrhage, but their architecture remains unclear. The morphometry of the microvasculature and hemorrhage of human carotid atheromatous plaques (CAPs) were evaluated, and 3-dimensional (3D) reconstruction of the microvessels was performed.Methods: CAPs were obtained by endarterectomy in 42 patients. The specimens were analyzed using light microscopy. Plaque hemorrhage was defined as an area-containing red blood cells (>1 mm2). To determine the histopathologic features of plaque hemorrhage, th...

Cerebral Microbleeds and Asymptomatic Cerebral Infarctions in Patients with Atrial Fibrillation
Conclusions: Patients with AF had a significantly higher prevalence of CMBs. The presence of CMBs in the baseline MRI may predict the consequent onset of an ACI and increase in CMBs in patients with AF.

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.

Association between Microbleeds Observed on T2*-weighted Magnetic Resonance Images and Dysphagia in Patients with Acute Supratentorial Cerebral Hemorrhage

Subdural and Intracerebral Hemorrhage Caused by Spontaneous Bleeding in the Middle Meningeal Artery after Coil Embolization of a Cerebral Aneurysm
Nontraumatic acute subdural hemorrhage (SDH) with intracerebral hemorrhage (ICH) is rare and is usually caused by severe bleeding from aneurysms or arteriovenous fistulas. We encountered a very rare case of spontaneous bleeding from the middle meningeal artery (MMA), which caused hemorrhage in the temporal lobe and subdural space 2 weeks after coil embolization of an ipsilateral, unruptured internal cerebral artery aneurysm in the cavernous portion. At onset, the distribution of hematoma on a computed tomography scan led us to believe that the treated intracavernous aneurysm could bleed into the intradural space. Emergenc...

Intracranial Vascular Calcification is Protective from Vasospasm after Aneurysmal Subarachnoid Hemorrhage
The objective of this study was to assess the association between intracranial calcification, a marker for atherosclerosis, and vasospasm. Charts and nonenhanced computed tomography scans of patients with subarachnoid hemorrhage were retrospectively reviewed. Transcranial Doppler studies were used to categorize vasospasm using mean flow velocity: mild vasospasm 120-199 cm/second and severe ≥200 cm/second.
