Impact Exploration of Spatiotemporal Feature Derivation and Selection on Machine Learning-Based Predictive Models for Post-Embolization Cerebral Aneurysm Recanalization
To enhance the performance of machine learning (ML) models for the post-embolization recanalization of cerebral aneurysms, we evaluated the impact of hemodynamic feature derivation and selection method on six ...

Open AccessHemodynamic factor evaluation using computational fluid dynamics analysis for de novo bleb formation in unruptured intracranial aneurysms
Although bleb formation increases the risk of rupture of intracranial aneurysms, previous computational fluid dynamic (CFD) studies have been unable to identify robust causative hemodynamic factors, due to the...

Follow-up study of a patient with early onset cerebral amyloid angiopathy following childhood cadaveric dural graft
We retrospectively studied the T2 star (T2*)-weighted magnetic resonance imaging (MRI) of a 40-year-old patient diagnosed with symptomatic early-onset cerebral amyloid angiopathy (CAA), occurring 34 years foll...

Open AccessPrediction of internal carotid artery aneurysm recurrence by pressure difference at the coil mass surface
A previous study on computational fluid dynamics reported that a high pressure difference (PD) at the surface of a coil mass is a strong predictor of aneurysm recurrence after coil embolization. PD was calcula...

Radiological and endocrinological evaluations with grading of hypothalamic perifocal edema caused by craniopharyngiomas
Hypophysial and hypothalamic dysfunction caused by craniopharyngioma is a serious problem despite the progress of surgical approaches and techniques. Perifocal edema induced by craniopharyngioma could be specu...

Inflow hemodynamics evaluated by using four-dimensional flow magnetic resonance imaging and the size ratio of unruptured cerebral aneurysms
Prediction of the rupture risk is critical for the identification of unruptured cerebral aneurysms (UCAs) eligible for invasive treatments. The size ratio (SR) is a strong morphological predictor for rupture. ...

Delayed asymptomatic coil migrations toward different arteries after aneurysmal embolization: case report
Delayed coil migration after endovascular treatment with detachable coils, particularly several months after treatment, is extremely rare. In this report, the authors describe a 77-year-old female in whom dela...

Pseudoaneurysm formation caused by the withdrawal of a Trevo ProVue stent at a tortuous cerebral vessel: a case report
This is the first report on the mechanism of pseudoaneurysm formation after withdrawal of a stent retriever. A 79-year-old woman developed cardiogenic embolization of the distal middle cerebral artery (M2). Th...

Molecular analysis of a recurrent glioblastoma treated with bevacizumab
We treated a case of recurrent glioblastoma (GBM) with bevacizumab and assessed its effect biologically. A 55-year-old man with a left frontal lobe GBM was experiencing recurrence 7 months postoperation. We ad...

Association between carotid plaque composition assessed by multidetector computed tomography and cerebral embolism after carotid stenting
We aimed to assess the relationship between atherosclerotic carotid plaque composition analyzed using multidetector computed tomography (MDCT) and the appearance of new ischemic lesions detected by diffusion-w...

MGMT promoter methylation and temozolomide response in choroid plexus carcinoma
Choroid plexus carcinoma (CPC) is a malignant tumor with a strong tendency to spread along the cerebrospinal fluid pathway. There is no standardized chemotherapy protocol for this rare tumor. We report a 38-ye...
