OBJECTIVE The presence of a cerebrospinal fluid (CSF) shunt is a predisposing factor for the development of subdural hematoma (SDH) in patients with hydrocephalus. However, few reports have addressed how patients with a CSF shunt should be treated in the event of traumatic acute SDH. The purpose of this study was to show how post-traumatic management of CSF(More)
Here we describe the case of a patient with a wide-necked unruptured aneurysm arising at origin of a persistent primitive trigeminal artery (PTA) variant from the right internal carotid artery (ICA), supplying the territory of the right superior cerebellar artery and the anterior inferior cerebellar artery. To preserve the ICA and the PTA variant, coil(More)
Malignant gliomas of the optic pathway are rare, and their genetic alterations are poorly understood. We describe a 64-year-old woman with anaplastic astrocytoma originating from the optic pathway, together with the molecular features. She presented with progressive visual field loss, and a biopsy sample was obtained from the lesion in the optic chiasm. She(More)
The introduction of the balloon remodeling and stent-assisted technique has revolutionized the approach to coil embolization for wide-neck aneurysms. The purpose of this study was to determine the frequency of thromboembolic events associated with single balloon-assisted, double balloon-assisted, and stent-assisted coil embolization for asymptomatic(More)
The characteristics of intracerebral hemorrhage (ICH) accompanying chronic liver disease (CLD) were investigated in ICH patients hospitalized between 1998 and 2008 divided into the CLD group (55 ICHs in 49 patients) and the idiopathic group without CLD (668 ICHs in 648 patients). The CLD group included a subgroup with liver cirrhosis (LC). Age, sex, history(More)
Chondromas are rare benign tumors that commonly originate from the base of the skull, while those arising from the dura mater are less common. Although the molecular mechanism underlying its pathogenesis remains largely unknown, 12q13-15 rearrangements followed by the activation of HMGA2, which is associated with cell proliferation, have been reported in(More)
INTRODUCTION Glioblastoma multiforme (GBM) is a very rare type of tumor involving the pineal region. No case of pineal region GBM with tumoral hemorrhage has ever been reported. Here, we present the first such case report. CASE REPORT A 65-year-old man presented with sudden-onset disturbance of consciousness. CT revealed intraventricular hemorrhage and(More)
A 9-year-old girl struck the left side of her head on a doorknob, after which she gradually developed swelling. She was treated conservatively at another hospital before being referred and admitted to our hospital 9 days after injury, with complaints of exophthalmos and diplopia. Computed tomography (CT) scanning and magnetic resonance imaging (MRI)(More)
OBJECTIVE Ruptured aneurysms arising from non-branching sites of the internal carotid artery (ICA) are often difficult to treat by neck clipping or endosaccular coiling. We discuss the feasibility of simple endovascular ICA ligation or trapping to treat aneurysms. METHODS Data from eleven patients were retrospectively analyzed regarding Hunt and Hess(More)
We investigated endovascular treatment for 10 mm or larger aneurysms in the internal carotid artery (IC), including the cavernous portion, the paraclinoid portion, and the posterior communication artery (PC). Between 2011 and 2014 at our hospital, there were 35 cases of aneurysms that were 10 mm or larger in the carotid artery. We analyzed these 35 cases(More)
