Cerebellopontine angle (CPA) tumors are uncommon in children, and the pathological spectrum is different from that of adults. In this study, we reviewed the pathological diagnosis of pediatric patients with a CPA tumor to determine the pattern in this age group. In a cohort of 267 patients with posterior fossa tumor, tumor locations were determined with(More)
The indication of surgical treatment for intracranial arachnoid cysts (ACs) is a controversial issue. In this study, we reviewed surgical outcomes of intracranial ACs that were treated with endoscopic fenestration or microscopic fenestration, which are currently standard practices for surgical treatment of AC. In addition, we also evaluated the validity of(More)
Cranial distraction osteogenesis (DO) has many advantages for correcting skull deformities: Thus, DO is extensively used for the treatment of skull deformities. However, diverse, unexpected complications are associated with this procedure. In this study, we present the surgical outcomes and complications of DO. Moreover, we propose a modified protocol for(More)
OBJECTIVE In a minority of patients with neurofibromatosis Type 1 (NF-1), cerebral vasculopathy reminiscent of moyamoya disease develops. This phenomenon is called moyamoya syndrome (MMS), but there are no known risk factors for the prediction of MMS in NF-1 patients. Polymorphism of the RNF213 gene has exhibited strong associations with familial and(More)
C57BL/6J mice have been widely used as a diet-induced obesity model because they trigger common features of the human metabolic syndrome. In the present study, C57BL/6J male mice were fed either a high-fat diet (HFD) or normal diet (ND) during a 24-week period, and then the age-dependent liver proteome of mice in two groups was analyzed using 2-DE combined(More)
In neuro-oncology, the biology of neural stem cells (NSCs) has been pursued in two ways: as tumor-initiating cells (TICs) and as a potential cell-based vehicle for gene therapy. NSCs as well as mesenchymal stem cells (MSCs) have been reported to possess tumor tropism capacities. However, there is little data on the migratory capacity of MSCs toward brain(More)
Moyamoya disease (MMD) is a chronic cerebrovascular occlusive disease, and progressive involvement of the posterior cerebral artery (PCA) has been reported. However, majority of MMD articles are presenting classic anterior circulation related issues. This study investigates the preoperative factors related to the long-term outcome of posterior circulation(More)
OBJECT Neurofibromatosis Type 2 (NF2) is an autosomal-dominant inherited disease, characterized by multiple neoplasia syndromes, including meningioma, schwannoma, glioma, and ependymoma. In this report, the authors present their clinical experience with pediatric NF2 patients. In particular, they focused on the clinical course of vestibular schwannoma (VS),(More)
