Osteochondromas are common, benign tumors in the long bones, but osteochondromas are rare in the vertebrae. Most vertebral osteochondromas arise from the cervical or upper thoracic spine. However, lumbar osteochondromas have rarely been reported. In this report, a rare case of a lumbar osteochondroma arising from the spondylolytic L3 lamina in a 57-year-old(More)
Choroid plexus cysts (CPCs) are the most common neuroepithelial cysts, occurring in more than 50% of some autopsy series. They are typically small and asymptomatic and are discovered incidentally in older patients, usually in the trigone of the lateral ventricle. Symptomatic CPCs (usually exceptionally large, 2-8 cm) are rare. The authors report a case of(More)
OBJECTIVE The purpose of this study is to evaluate the clinical characteristics and surgical outcome of cerebellopontine angle (CPA) epidermoids presenting with trigeminal neuralgia. METHODS Between 1996 and 2004, 10 patients with typical symptoms of trigeminal neuralgia were found to have cerebellopontine angle epidermoids and treated surgically at our(More)
Oxidative stress is known to induce cell death in a wide variety of cell types, apparently by modulating intracellular signaling pathways. Activation of extracellular signal-regulated kinase (ERK) in oxidative stress remains controversial. In some cellular systems, the ERK activation is associated with protection against oxidative stress, while in other(More)
This prospective study was performed to determine the efficacy, safety, and tolerability of concurrent chemoradiotherapy (CCRT) followed by adjuvant chemotherapy with temozolomide (TMZ) in the treatment of patients with WHO grade III gliomas. Thirty-three adult patients with WHO grade III glioma and aged >17 years were enrolled from three institutions(More)
Cerebrospinal fluid (CSF) diversion is an essential component of neurosurgical care, but the rates and significance of hemorrhage associated with external ventricular drainage (EVD) and ventriculoperitoneal (VP) shunt procedures have not been well quantified. In this retrospective study, the authors examined the frequencies of hemorrhagic complications(More)
OBJECTIVE The secondary verification of Leksell Gamma Knife treatment planning system (LGP) (which is the primary verification system) is extremely important in order to minimize the risk of treatment errors. Although prior methods have been developed to verify maximum dose and treatment time, none have studied maximum dose coordinates and treatment volume.(More)
Allicin, the main flavor compound in garlic, has anti-carcinogenic activities in a range of cancer cells, however, the underlying molecular mechanisms are not completely understood. This study examined the effect of allicin on the cell viability of U87MG human glioma cells along with its molecular mechanisms of induction(More)
BACKGROUND Endovascular internal trapping is an effective procedure for the treatment of acute vertebral artery dissection (VAD). However, the outcomes of reconstructive treatment have not been well established. The aim of our study is to evaluate the long-term clinical and angiographic results of endovascular internal trapping or reconstructive treatment(More)
Glioblastoma multiforme (GBM) is the most aggressive intracranial tumor and it commonly spreads by direct extension and infiltration into the adjacent brain tissue and along the white matter tract. The metastatic spread of GBM outside of the central nervous system (CNS) is rare. The possible mechanisms of extraneural metastasis of the GBM have been(More)
