Genetic Analysis of c.14576G>A Variant in Nonatherosclerotic Quasi-Moyamoya Disease
Quasi-moyamoya disease (MMD) and MMD (definite MMD) have similar cerebral angiographic features, but whether these related diseases have similar etiology or genetic background remains unclear. Recently, we have reported that the recently identified MMD susceptibility gene variant RNF213 c.14576G>A (rs112735431) was associated with atherosclerotic intracranial major artery stenosis/occlusion. The present study investigated the occurrence of RNF213 c.14576G>A in patients with nonatherosclerotic quasi-MMD.

Rupture of an Aneurysm of the Superior Cerebellar Artery Feeding a Dural Arteriovenous Fistula
We experienced a very rare case of bleeding from an aneurysm of a branch of the superior cerebellar artery, which feeds a dural arteriovenous fistula (DAVF) of the posterior fossa. The aneurysm was not detected on initial angiography and 2 episodes of rebleeding resulted in deterioration of the patient's condition. Although rare, aneurysms of the pial feeding arteries should be considered as a cause of bleeding in cases of DAVF.

X-ray Angiography Perfusion Analysis for the Balloon Occlusion Test of the Internal Carotid Artery
A perfusion study should be performed during the balloon occlusion test (BOT) to prevent ischemic events after therapeutic carotid occlusion. We evaluated the efficacy of X-ray angiography perfusion analysis during the BOT.

Surgical Revascularization in North American Adults with Moyamoya Phenomenon: Long-Term Angiographic Follow-up
North American and Asian forms of moyamoya have distinct clinical characteristics. Asian adults with moyamoya are known to respond better to direct versus indirect revascularization. It is unclear whether North American adults with moyamoya have a similar long-term angiographic response to direct versus indirect bypass.

Ruptured Cerebral Microaneurysm Diagnosed by 3-Dimensional Fast Spin-Echo T1 Imaging with Variable Flip Angles
Cerebral microaneurysms, which are 2 mm or small in size, are a rare cause of subarachnoid hemorrhage (SAH). The authors present 2 cases with ruptured microaneurysms, in which 3-dimensional (3D) fast spin-echo T1 imaging with variable flip angles (CUBE T1) using gadolinium-diethylenetriaminepentaacetic acid (Gd) enhancement was useful in diagnosing the microaneurysms as the source of bleeding. Case 1 was a 61-year-old woman who had an SAH localized to the left Sylvian fissure. A small bulge (1.4 mm) at the bifurcation of left middle cerebral artery (MCA), which was detected by 3D angiography, was well enhanced by CUBE T1...

The Circle of Willis and White Matter Lesions in Patients with Carotid Atherosclerosis
The correlation between cerebral atherosclerosis and white matter lesions (WMLs) in the elderly was controversial in the published articles, where the stenosis was often evaluated by ultrasonography, computed tomography angiography, or magnetic resonance angiography and collaterals were seldom considered. We hypothesized that collaterals influence WMLs. Our study was to explore the relationship between the circle of Willis and WMLs in a retrospective, hospital-based cohort of patients with carotid atherosclerosis.

Endovascular Therapy of Cerebral Arterial Occlusions: Intracranial Atherosclerosis versus Embolism
Treatment strategy for acute arterial occlusions due to intracranial atherosclerotic disease (IAD) may differ from those due to embolism (embolic). The aims were to differentiate and classify angiographically defined occlusion due to IAD versus embolism and identify baseline clinical factors associated with IAD-related occlusion.

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.

Predictors of a Favorable Outcome after Recanalization in Patients with Cerebral Major Vessel Occlusion
Although tissue plasminogen activator and endovascular treatment were reported to be useful for recanalization in patients with major vessel occlusion (MVO), the outcome in some patients with recanalization was unfavorable. We could detect prolongation of the ipsilateral posterior cerebral artery (PCA) to the ischemic side on magnetic resonance angiography in some patients (ipsilateral-PCA sign). We investigated the predictors including radiological findings for a favorable outcome after successful recanalization.

Report of Dramatic Improvement after a Lumboperitoneal Shunt Procedure in a Case of Anticoagulation Therapy-Resistant Cerebral Venous Thrombosis
Cerebral venous thrombosis (CVT), which typically progresses from either acute or subacute onset, presents with symptoms related to intracranial hypertension (e.g., headache and papilledema) and brain parenchymal lesions (e.g., aphasia and hemiplegia). Anticoagulation therapy is generally accepted as a treatment for CVT and often leads to good clinical outcomes. However, we experienced a case of CVT with an uncommon clinical course. The patient was a 63-year-old man who presented with headache, papilledema, visual loss, and diplopia; his condition gradually deteriorated, and he was diagnosed with CVT via cerebral angiography.

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...

Relationship between Angiographic Results and Morphology in Sidewall Intracranial Aneurysms after Stent-Assisted Coil Embolization
Stent-assisted coil embolization (SACE) is used to address wide-necked or complex aneurysms. However, as they may recanalize after SACE, predictors of recanalization are needed. We investigated the relationship between follow-up angiographic results and the morphology of sidewall (SW) aneurysms in patients treated by SACE.

A Case of Unexpected Symptomatic Vasospasm after Clipping Surgery for an Unruptured Intracranial Aneurysm
We report a case of a 62-year-old woman who presented with symptomatic vasospasm 11 days after clipping surgery for an unruptured aneurysm. We could not predict the existence of vasospasm until ischemic symptoms developed. We retrospectively found mild vasospasm in the computed tomography angiogram taken 8 days after the operation. The patient complained of a prolonged unexpected headache 1 week after the operation.

Time-Resolved 4-Dimensional Computed-Tomography Angiography Can Correctly Identify Carotid Pseudo-Occlusion
We present an 82-year-old man with a symptomatic critical internal carotid artery, which was detected on time-resolved 4-dimensional computed-tomography angiography, whereas single-phase computed-tomography angiography, magnetic resonance angiography, and Doppler ultrasonography suggested apparent occlusion.
