Basal Ganglia Cerebral Microbleeds and Global Cognitive Function: The Kashima Scan Study
We previously showed that global cognitive function was associated with deep or infratentorial (D/I) cerebral microbleeds (CMBs) in a Japanese healthy cohort. We continually recruited participates and performed further investigation to focus on the impact of different distributions of D/I CMBs on gradient-echo magnetic resonance imaging on global cognitive function.

Parkinsonism after External Ventricular Drainage in a Patient with Intraventricular Hemorrhage
We report a patient who presented with Parkinsonism after external ventricular drainage (EVD) for an intraventricular hemorrhage (IVH). We also demonstrate dopaminergic system dysfunction using 18F-florinated-N-3-fluoropropyl-2-β-carboxymethoxy-3-β-(4-lodophenyl) nortropane (18F-FP-CIT) positron emission tomography (PET) scanning. A 50-year-old woman presented with manifestations of Parkinsonism, including severe rigidity and 3-Hz resting tremor, immediately after EVD for IVH. 18F-FP-CIT PET images at 6 months after onset showed dysfunction of the bilateral caudate nuclei and putamen after EVD that seemed to have induce...

Do Not Forget Susac Syndrome in Patients with Unexplained Acute Confusion
To report 2 patients with Susac syndrome presenting with acute confusion and abnormal neuroimaging and cerebrospinal fluid (CSF) findings, both of whom were initially misdiagnosed. Susac syndrome is a rare, though likely underdiagnosed, endotheliopathy defined clinically by the triad of encephalopathy, branch retinal artery occlusions (BRAOs), and sensorineural hearing loss (SNHL). Its pathogenesis remains poorly understood. The classic clinical triad may not be fully developed at initial presentation, even at the time magnetic resonance imaging (MRI) demonstrates characteristic central corpus callosum lesions.

Brain Microbleeds 12 Years after Orthotopic Liver Transplantation in Val30Met Amyloidosis
Unexplained focal neurologic episodes (FNEs) can occur in patients with transthyretin-related familial amyloidotic polyneuropathy (TTR-FAP) after orthotopic liver transplantation (OLT). A patient with Val30Met FAP underwent OLT at age 34 years. Twelve years after transplantation, she presented with recurrent FNEs lasting from 10 minutes to 8 hours each, with nonuniform deficitary clinical features and variably associated with headache. Magnetic resonance imaging showed multiple brain microbleeds and diffuse contrast enhancement of the craniospinal leptomeninges consistent with amyloid deposits.

Apparent Diffusion Coefficient and Transient Neurological Deficit after Revascularization Surgery in Moyamoya Disease
This study investigated whether the apparent diffusion coefficient (ADC) in normal-appearing white matter (NAWM) on magnetic resonance imaging could offer a predictor of postoperative transient neurological deficits.

Malignant Middle Cerebral Artery Infarction Resulting from Dissection of Middle Cerebral Artery
A 30-year-old man presented with headache, left hemiparesis, and uncal herniation. Magnetic resonance imaging showed acute infarction in the right middle cerebral artery (MCA). Lifesaving craniotomy proceeded because of the uncal herniation. Assessment of brain tissue led to a diagnosis of MCA dissection. His skin biopsy showed ultrastructural abnormalities of dermal connective tissue. This is the unique case that dissection was diagnosed from both a biopsy specimen of the MCA and the dermal connective tissue.

Vasospastic Amaurosis Fugax Diagnosed by Cerebral Angiography
We report a case of recurrent monocular blindness presumed to be caused by vasospasm, demonstrated by digital subtraction angiography. Case report: A 65-year-old man presented with recurrent visual loss in the left eye for 2 years. He had histories of hypertension, cigarette smoking, and May–Thurner syndrome. The symptom occurred variably from twice a day to once a week and usually lasted for 5 minutes. Brain magnetic resonance imaging, magnetic resonance angiography, and ophthalmologic evaluation did not reveal any abnormality.

Leisure-Time Physical Inactivity Associated with Vascular Depression or Apathy in Community-Dwelling Elderly Subjects: The Sefuri Study
We examined 317 community-dwelling elderly subjects (137 men and 180 women with a mean age of 64.5 years) without dementia or clinically apparent depression.

Case of Cerebral Amyloid Angiopathy-Related Inflammation – Is the Absence of Cerebral Microbleeds A Good Prognostic Sign?
Objective: The aim of this study is to describe a case of pathologically proven cerebral amyloid angiopathy-related inflammation (CAA-I) without cerebral microbleeds (CMBs) and its clinical course. Background: CAA-I is an uncommon variant of cerebral amyloid angiopathy. Keys to diagnosis rely on the physician's awareness of this entity, CMBs on magnetic resonance imaging (MRI), an often favorable response to immunosuppression, and ultimately brain biopsy. CAA-I with no CMBs is rarely reported. Results: A 76-year-old woman presented with 4 weeks of headaches and was found to have visual neglect on the left part of the visual field.

Epileptic Ictal Hyperperfusion on Arterial Spin Labeling Perfusion and Diffusion-Weighted Magnetic Resonance Images in Posterior Reversible Encephalopathy Syndrome
The hemodynamic state of the posterior dominant vasogenic edema in posterior reversible encephalopathy syndrome (PRES) is controversial. The aim of this retrospective study was to examine the contribution of epileptic ictal hyperperfusion in patients with PRES using combined magnetic resonance perfusion imaging with arterial spin labeling (ASL) and diffusion-weighted magnetic resonance imaging (MRI).

Percutaneous Transluminal Angioplasty Improved Posterior Reversible Encephalopathy Syndrome due to Renovascular Hypertension
A 51-year-old man was admitted to our hospital complaining of preceding throbbing headache and tonic convulsions. Headache and convulsive seizure disappeared and his consciousness recovered to alert within 2 hours after onset. Neurological examination showed no abnormal findings. Laboratory examinations revealed high low-density lipoprotein cholesterol (179 mg/dL), renin (42 ng/mL/hour), aldosterone (265 pg/mL), noradrenaline (1031 pg/mL), and dopamine (79 pg/mL). In brain magnetic resonance imaging (MRI), fluid-attenuated inversion recovery, but not the diffusion-weighted image, showed high signal intensities in...

Three-Dimensional Optical Frequency Domain Imaging Evaluation of Novel Dual-Layered Carotid Stent Implantation for Vulnerable Carotid Plaque
Plaque prolapse through the cell stent has been suggested as one of the major causes of postprocedural distal embolization after carotid artery stenting. A CASPER stent (Terumo, Tokyo, Japan) is the latest-generation stent having the dual layers and expected to reduce the risk of embolization. A 76-year-old male asymptomatic patient with high-grade stenosis in the left internal carotid artery received carotid artery stenting. Preoperative magnetic resonance imaging demonstrated very high intensity signals on T1-weighted images.
