BACKGROUND Arteriovenous malformations (AVMs) of the scalp are relatively rare, and their precise natural course remains to be elucidated. We encountered a patient with a scalp AVM that progressively enlarged over the course of 3 years by capturing feeders from intracranial arteries. To our knowledge, ours is the first serial angiographic depiction of the(More)
The combination of trigeminal neuralgia and ipsilateral hemifacial spasm, known as painful tic convulsif (PTC), is a relatively rare entity in neurovascular compression syndrome. A case of PTC attributable to different offending arteries is described, the mechanisms and characteristics of PTC are discussed, and a review of the literature is presented. This(More)
BACKGROUND Vertebral artery dissecting aneurysm is now increasingly recognized as a cause of posterior circulation stroke in young adults. Here, we report a case of bilateral VADA with SAH, treated by bilateral coil occlusion using GDCs. CASE DESCRIPTION A 64-year-old woman was admitted to our hospital with consciousness disturbance (Hunt and Kosnik:(More)
A traumatic carotid-cavernous fistula and an intracranial pseudoaneurysm are uncommon but well-known complications of head trauma. A rare subtype of arteriovenous fistula may occur from a pseudoaneurysm of the anterior communicating artery (AcoA) instead of the internal carotid artery. We describe a patient with a traumatic pseudoaneurysm of the AcoA with a(More)
Digital subtraction angiography (DSA) is the preferred method for confirming dural arteriovenous fistulas (DAVFs), but it has the disadvantage of being invasive. In contrast, time-resolved magnetic resonance angiography (TR-MRA) is a useful, noninvasive imaging technique. The aim of this study was to compare the evaluation of DAVFs of the cavernous sinus(More)
We report a case of hemorrhagic giant cell tumor (GCT) of the temporal bone in a 77-year-old woman. The patient suffered from sudden-onset headache and vomiting associated with left temporal hemorrhage. MRI revealed a left temporal extradural mass lesion expanding to the subtemporal fossa, showing strong hypointensity on T(2)-weighted imaging. Subsequent(More)
BACKGROUND Tentorial dAVMs as a cause of trigeminal neuralgia are extremely rare. Consensus exists that radical treatment of such high-flow dAVMs should be considered because of their high risk of bleeding. The authors present a case of a 50-year-old man who presented with symptoms of tic douloureux caused by tentorial dAVM, which was treated successfully(More)
The treatment for patients with near occlusion of the cervical internal carotid artery (ICA) is controversial. The aim of this study was to examine the results of carotid artery stenting (CAS) as a surgical treatment for ICA near occlusion. Between April 2008 and September 2012, 14 patients (all men; mean age, 75.4 years) with ICA near occlusion were(More)
BACKGROUND In treating cavernous sinus dural arteriovenous fistulae (CSdAVFs), transvenous embolization of the whole affected sinus is usually performed, which may result in the disturbance of normal venous drainage or permanent cranial nerve palsy. OBJECTIVE To describe superselective shunt occlusion of CSdAVFs. METHODS Between July 2005 and August(More)
INTRODUCTION Our aim was to systematically investigate radiographic characteristics and outcome of diffusion-weighted imaging (DWI) changes in the elective coiling of unruptured cerebral aneurysm with analyzing the correlation of antiplatelet therapy (APT). METHODS In a total of 34 consecutive patients with unruptured cerebral aneurysms initially treated(More)
