Successful endovascular treatment of a ruptured saccular aneurysm arising from a fenestrated proximal anterior cerebral artery Open
Aneurysms arising from fenestrated proximal anterior cerebral arteries are rare. Previous studies primarily reported performing clipping. In contrast, endovascular treatment is rarely selected. In this report, we present a case of coil emb…

Case Reports: Two Different Onset Types of Chronic Encapsulated Intracerebral Hematoma related to cerebrospinal fluid perfusion identified prior to and following surgery Open
Hypertensive intracerebral hemorrhage rarely develops into chronic encapsulated intracerebral hematoma (CEIH). We encountered 2 cases of CEIH, one with initial CEIH and the other with CEIH following minimally invasive endoscopic surgery fo…

Presence of intra-aneurysmal thrombi with delayed coil migration after embolization of an aneurysmal subarachnoid hemorrhage: illustrative case Open
BACKGROUND Coil migration is a rare, but notable complication of endovascular treatment. Risk factors include communicating segment aneurysms, aneurysmal shape, and technical factors. Although cerebral blood flow obstruction caused by earl…

Manual superficial temporal artery compression using a circular plastic material for embolization of meningioma: illustrative case Open
BACKGROUND In meningiomas that occur in the high-convexity region, the superficial temporal artery (STA) frequently feeds the tumor, and when embolizing from the middle meningeal artery (MMA), the embolic material may not reach the tumor v…

Favorable management of symptomatic cerebellar hemangioblastoma presenting with obstructive hydrocephalus during pregnancy: A case report and literature review Open
Background: Cerebellar hemangioblastoma is a highly vascular benign tumor and the growth rate of hemangioblastomas is believed to often accelerate during pregnancy; however, the reason for this rapid increase in size remains poorly underst…

Supplementary Material for: Intra-Plaque Vessels on Contrast-Enhanced Ultrasound Sonography Predict Carotid Plaque Histology Open
Background and Purpose: Although the echogenicity of carotid plaques on carotid enhanced ultrasound (CEUS) was reported to correlate with the historological density of intra-plaque neovessels, it is unclear whether the intra-…
