OBJECT Intraspinal hemangioblastomas are relatively uncommon benign tumors. The surgical strategies remain controversial, and the risk factors with regard to clinical outcome are unclear. The purpose of this study was to analyze the clinical characteristics, imaging findings, surgical strategies, and functional outcomes associated with intraspinal(More)
Spinal cord subependymomas are very rare. Most studies on spinal cord subependymomas have been case reports with literature reviews. This study presented a surgical series of 13 patients with histologically proven spinal cord subependymomas. Their clinical data, radiological findings, operative records, and follow-up outcomes were reviewed. There were 5(More)
Ventricular dilation affects 7% to 10% of patients with Chiari type I malformation (CIM), but the choice of surgical treatment is controversial. To study the surgical approaches for treating CIM with ventricular dilation and to evaluate the efficacy of posterior fossa decompression (PFD), clinical and imaging data of 38 adult patients who received surgical(More)
OBJECT Cerebral arteriovenous malformations (AVMs) are congenital malformations that may grow in the language cortex but usually do not lead to aphasia. In contrast, language dysfunction is a common presentation for patients with a glioma that involves language areas. The authors attempted to demonstrate the difference in patterns of language cortex(More)
Intramedullary spinal cord gangliogliomas are rare tumors composed of glial components and ganglion cells. These gangliogliomas are generally considered as slow-growing tumors, corresponding histologically to WHO grade I or II. There are few reports of large case series of intramedullary spinal cord gangliogliomas from a single center. We retrospectively(More)
OBJECT Intramedullary neurenteric cysts (NECs) are exceedingly rare lesions and have been previously reported in case reports. The aim of this study was to determine the clinical manifestations, radiological features, and long-term prognosis of patients with such lesions. METHODS The authors retrospectively reviewed the records of 13 patients with an(More)
OBJECT Intramedullary schwannomas are exceedingly rare. Most previous studies are case reports with an associated literature review. The aim of this study was to discuss the clinical features and the outcomes of microsurgery for these rare lesions. METHODS The authors retrospectively reviewed the data of twenty patients with intramedullary schwannomas.(More)
Primary intramedullary germinomas are very rare tumors in the spinal cord. This study presented a series of 11 patients with histologically proven primary intramedullary spinal germinomas. Their clinical and radiological findings, treatment records and long-term outcomes were reviewed. There were four male and seven female patients with a mean age of 27.1(More)
Ornithine decarboxylase (ODC) plays a critical role in cell proliferation and is overexpressed in a variety of cancers. Furthermore, γ-aminobutyric acid (GABA) content and glutamate decarboxylase (GAD) activity are increased in neoplastic tissues in colon and breast cancer. However, few studies have examined these molecules in gallbladder cancer specimens.(More)
PURPOSE The aim of this study was to discuss the clinical manifestations, radiological features, treatment, and long-term outcomes of intraspinal ependymomas (Word Health Organization grade II) in pediatric patients. METHODS The data of 15 pediatric patients who underwent microsurgery for intraspinal grade II ependymomas were retrospectively reviewed.(More)
